Hello all. I have a 12 year old GE built-in oven and over the past
couple of months the interior oven light keeps burning out, I've gone
through about six or seven since Nov/Dec. The lamps generally burn out
when I open the door or push in the oven light switch, but not (with
one exception described below) after the bulb has lit up.

I did a Google search of web pages and newsgroups and came up with a
couple of threads, one about light bulbs around the house often
burning out and one about oven lights burning out. Both threads
suggested checking to make sure an impedance problem with the neutral
line wasn't causing an imbalance in the voltage on either side of the
neutral. Apparently, the symptom,would be a high voltage reading in
the socket.

I checked the voltage in one of the kitchen sockets and it read
118.2V. I then put one lead of the voltmeter on the copper center
contact of the oven light socket and the other lead on the threaded
part of the socket and read the same 118.2V.

As an experiment, I left one appliance bulb on for about 8 hours and
it survived and I turned off the light. But the next day when I opened
the oven door the bulb flashed and failed. I also tried a cheap 40W
regular bulb, which survived baking something in the oven but burned
out after a few hours when I experimentally left it on after I was
finished baking. That experiment was probably flawed though, maybe
regular bulbs don't survive baking.

I've tried GE, Philips and Home Depot appliance bulbs.

I partially pulled out the oven and could see where the oven was
connected to the house wiring. From what I could see, the wires were
connected with twist connectors and then the bottom of the connector
was wrapped in electrical tape.

The only thing I can think of is maybe the door and light switch are
corroded and when they make contact, they're making a bunch of
interrmittent contacts, cycling the bulb many times before a good
contact is made. That would effectively put the bulb through dozens
or hundreds of power cycles. That might burn out a bulb quickly and
explain why the bulbs haven't failed when I left them on for hours at
a time.

Does anyone have any experience with this kind of problem?

I'm not an electrician but is there anything else I can try to see
what the problem is?


Thanks.

Gas or electric oven?

My guess is it is electric, which means it is bringing in 240 V.
Further I am guessing that when you shut the oven door it is causing a short
to 240 or an opening of the neutral also causing 240V and a flash ending of
your lamp.

Clearly I am guessing, but if I am right, I would worry about more than
just oven lights, I would worry about frying the cook.

If it is gas, that blows my theory.

Ack, I gave all the details but the most obvious. Yes, it's an
electric oven.

AFAIK, the only connection the door has to 240V would be through the
light switch the closes when the door is closed.

Wouldn't a short to 240V cause the breaker to open?

take out the oven and repair the wires, the light socket, etc. its not
making good contact and this is whats burning them out so fast....
probably need a new metal socket for the ceramic light fixture in the
oven... if you replace the wires you need asbestoes covered
wires(probably not asbestos any more but most ace hardware stores will
have the wire you need)....

I was thinking of a short to 240V not accross 240. It could be the
switch somehow, I will have to think about that one, or it could be a loose
wire that is being pushed against another somehow.

Thanks for the reply.

Out of curiosity, what is it about poor contact among the wires that
causes the bulb to burn out? I know (as a somewhat unrelated example)
that the high voltage wires in a car ingnition system can break down,
reducing voltage and causing the spark plugs to misfire.

Does poor contact between the internal wiring and the socket cause a
similar low voltage situation? Or is arcing occuring, which is
damaging the bulb?

Also, is there anything I should specifically look or test for when I
have the oven out? Is there a way to tell if the wire or socket is at
fault?

A poor contact causes heat. The heat is transferred to the bulb's filament
shortening its life. I would think in that case it is just coincidence that
it failed when initially energized or the filament weakened when it cooled
and just 'gave up the ghost' when powered again.

Discoloration would be the most likely sign although it may not always be
visible.

If it is a self cleaning range, some appliance manufacturers sell a bulb
specifically designed (so they say) for that application. Check local
*appliance parts* suppliers. You might also want to consider a replacement
bulb with a brass base in place of aluminum if the socket is brass as well.
Jenn Air ranges had a problem years ago when using a aluminum base bulbs in
their brass sockets.

??? The filament must already be burning in the range of 3000 degrees
C to 5000 degrees C. Check out this out this web site:

http://invsee.asu.edu/nmodules/lightbulbmod/filament.html

The heat generated by a poor contact can't be any appreciable fraction
of the normal temperature of a lamp filament, if it was 20% of 3000
degrees there would be a fire, or the wire would melt.

I may stand to be corrected, but I would guess the bulb normally uses
the socket to cool itself, but if the socket is hot it can't provide any
cooling so over heat.

Check your neutral connection. There is a possibility that with a high
resistance on the neutral, and some 120 volt system on one hot
line-to-neutral and the bulb on the other hot line-to-neutral that when
everything gets energized you're seeing significantly higher voltage across
the light.

Thanks for the reply. You must have missed my original post. I've
repeated it below. I don't think there's a problem with the neutral
connection because I measured the voltage at the socket at it was the
same as one of the kitchen sockets, 118.2V.

Ralph wisely suspected "Check your neutral connection. There is a

possibility that with a high
resistance on the neutral" Checking the voltage will not measure the
resistance normally, especially with a static system and today's digital
(very sensitive) meters.

I don't understand. I measured the voltage across the socket and it
was 118.2V. If the bulb were burning out because of a poor connection
to the neutral that resulted in high voltage, wouldn't I be able to
measure that higher voltage?

Even with a high resistance connection, with little current you will
still get full voltage if your meter has even higher resistance.

If the connection has 2K ohms and your meter has 2M ohms the full
voltage will be read. However if your meter has 2K and the connection has
2M then it will show a real voltage drop. Today's digital meters have very
high internal resistance so they then to miss some of the things the older
meters would pick up.

Not necessarily. Your meter puts no load on the connections. If you
have a poor connection on the neutral somewhere it might not show up
until it was under load (the bulb is on).

Explodes? Does it shower glass all over whatever is in the oven?

The OP didn't say whether or not there is a glass lens cover over the light housing, and if there is, how it seals the light socket against the oven heat. The OP also didn't say if the lamp burned out upon opening and closing the oven door when the temperature of the oven was maybe 200F vs 400F. He also didn't say if he was using special appliance bulbs that are designed to be super strong against vibration. Too many things we still don't know.

Sounds like someone forgot to re-install the heavy glass lens over the bulb. If
the bulb is bare and exposed in the oven, something is not right.

The oven is likely 220V.
The bulb is likely 120V.
I'd also check for intermittent neutral.

It happened to us recently. Had one light bulb that lasted at least 10 years. Then it died and I have been replacing the bulb 5 times in the last 1 month. Kept dying after just a few days. I wondered if the problem is with the recent bulbs quality/spec or the oven itself. I recalled in the past you buy separate bulbs for fridge and oven. Now it's the same bulb.

Before 2003, more like 1989, I had a lamp over
my workbench. Phillips brand bulbs would burn
out when I turned on the grinder. GE bulbs lasted
a lot longer than that.

Pehaps the poster from 2003 can get bulbs of a
different brand to try.

It could be a lot of things but screwing the bulb in too hard does cause this.

1/8th turn after it lights - not 1/4 - is all you need.

I had that problem a few months ago. The oven bulb burned out after a long life, so long I couldn't remember when I replaced it last. I bought a replacement at Home Depot and it burned out within a week. Bought another and the same thing happened. Based on advice from this group, I bought a 130 volt bulb on Amazon; it's still working.

I wonder how many of the people who say the bulbs keep burning out tested those bulbs in another fixture.

I have a gas stove in which the oven light goes off frequently, but not all the time, when the
oven is in use. It eventually comes back on, even while the oven is still hot. It's an intermittent
problem and I haven't been able to discern any time or temperature pattern.

I tried replacing the bulbs years ago, but it didn't help. The new bulb did the same thing.

It's probably an expansion thing with the socket, but I just live with it.

Get a flashlight, and place it near the stove. Use it to see the
contents of the oven. Problem solved!

I keep the flashlight in the refrigerator for that purpose but it's too dark in there and I can never find it without a flashlight.

My side by side at home has a steel cabinet and refrigerator magnets are all over it. I haven't come across a residential fridge with an aluminum cabinet yet but I haven't owned one of the latest units. o_O

Some of the stainless appliances have a steel "side skin".

Could it be possible to have a steel structure for strength with a thin SS sheet covering it? It seems to me that enough SS to build a strong enough cabinet would be very expensive and noncompetitive. o_O

You need to have the voltmeter connected semi-permanently to the oven bulb outlet so you can monitor the voltage when you first turn the oven on and when you open the door. It does not seem like it burns out on a steady state basis, only on turn-on transients, and you will not see them if you have to open the oven door to connect your voltmeter. You need a screw-in outlet and an extension cord so you can monitor the voltage at turn-on. Even better would be an oscilloscope so you can see the actual transient. If you have a loose neutral anywhere in the circuit, you might have a high transient. For instance, if the timer motor is on the other half of the split 240 Volt circuit, the motor inductance will have a varying impedance at the time the light turns on, and that could screw up the balance of the circuit if the neutral is loose.

I too started having problems with my 2012 GE Profile built in convection oven. Initially, he light bulbs would intermittently go off and on when the oven was in use, and then eventually burn out. I felt I had a phantom in the oven. Now they just burn out. In the past 3 months I am replacing both oven appliance bulbs at a rate of once a month. My oven has 2 bulbs located on the upper surface and they have a glass cover which can be a pain to get off. I tried looking at the sockets with a mirror to see if I could detect anything. It's very frustrating and I am not electrical. Don't see how I could do any of the tests some of the others have done. Guess I'll just keep replacing for now. I just bought a 25 watt bulb instead of a 40 watt to see if that makes any difference.

From Michigan:
We bought a GE Electric Range last September and it was delivered with a burned out oven light. We purchased another 40w appliance bulb and it burned out within a week. A 3rd bulb burned out as well. We called GE Service Center. The technition came and said it was the light bulbs that were at fault. Not that we were using the wrong kind, but all the appliance bulbs available were not made up to the quality they used to be. He recommended we get a rough surface shop-light bulb for the oven. We shopped three places to buy one. Those bulbs don't exist in a 40w bulb small enough to fit in the oven and be able to install the safety glass cover that came with the oven protect the light bulb. GE replaced the main control panel and the temperature senser in the oven in late December, and a week later another bulb burned out while using the oven. GE came back again, tested the oven, and said again it was the quality of the bulbs at fault. The GE bulbs we purchased were made in Hungary. We bought other Phillips bappliance bulbs made in the Phillipines, and still another brand from China. I asked sales managers at three appliance stores if anyone reported oven bulbs from any appliance manufacturers burning out. Their answers were all no. GE tested the bulb socket inside the oven, and said the current and volts to the bulbs was OK. Could it be that the main control panel which completely controls the oven temperature, the clock, burners, the oven timer and clock, as well as the oven light, be at fault, at times sending too much voltage to the oven light? I don't believe it's the light bulbs. It acts like a faulty circuit board, that fails when asked to do too much. The bulbs have flashed and burned out when we turn on the oven light while the oven is cooking something. GE Oven Model # JB650DFBB.

Try measuring the voltage at the bulb or if this is too hard to reach, the
voltage on each side of the 240 volt wiring on the back of the oven. No
more than most oven bulbs are used I would think they should last many years
unless you turn on the bulb and leave it on while doing the cooking.

It may be a voltage unbalance that is causing the side with the bulb to have
more voltage than it should. Do this several times and with different
things running in the house. It may not be the stove that is at fault for
this, but other things in the house could if there is a bad connection to
the neutral wiring in the house.

I'd think it unlikely and, if that were the case, wouldn't the new bulb
act like a flashbulb (anyone remember those?<g>) the first time it was
turned on?

I've noticed the same problem of late with our oven. The OEM bulb,
IIRC, seemed to last us about 7 years with moderate use. The
replacements seem to crap out annually. Tried a variety of bulbs
(different makers) that were all specified as being appliance bulbs for
use in ovens. Never noticed any difference in the brightness only the
longevity or lack thereof.

I believe it to be the latter. NOTHING has been changed in the
electrical panel nor the stove. Usage of the oven light is not
excessive - if anything it's likely down from that of the first 7 years.

Wow. My oven bulb is 37 years old. I don't open the oven door that
much, and I never turn the light on when the door's not open, but I do
use the oven 75 times a year, probably .

My refrigerator bulb might have been replaced once in 37 years.

Aren't "appliance" bulbs coated in plastic so that if they shatter,
they don't get glass all over the inside of the appliance? Isn't that
and that they are smaller than some other bulbs of the same wattage
what makes them "Appliance Bulbs"?

If this is true, could he reverse the two hots, at the socket or where
the cord connects to the oven, so that he's have less than 120 instead
of more, on the bulb? The heating elements would still get full
voltage. It would also be less on the control panel, but I'd be
surprised if that needed more than 100v to run right.

No, AFAIK, there is no special coating on the "appliance" bulbs. You're
thinking of the "rough service" bulbs, like for garage trouble lights,
etc. where they tend to get banged around. ... or used to. Most have a
LED set up now or fluorescent tube encased in plastic tube.

They are a smaller form factor than regular bulbs but with the same base
(A19?). Clear or frosted.

I'm beginning to think the only thing that makes them appliance bulbs is
that wording on the package<g>

I can't tell you which bulb is the best, but the one that JUST burned
out after less than 45 days in service was a Westinghouse, clear, 40watt
appliance bulb.

We'll see how its brother/sister do as I stocked up with three of them
in December.

I just looked at our Maytag gas range...it's about 15 yrs old and I've never changed the bulb. All I can tell you is that the bulb is inside of a tempered glass half-round cover held on with a wire bail.

A common cause of premature bulb failure is a loose connection
in the wiring to the bulb.
Sometimes it's even in the bulb socket base.

I have a 5 year old GE Profile Electric DOUBLE Wall oven. Convection on top. Conventional Oven on bottom. There are two bulbs in each oven with glass covers. I cannot keep bulbs burning in the top oven. Either Socket. The bottom oven is no problem. Bulbs in the bottom oven last years. The double oven has a single 220 volt service with neutral. So this eliminates a neutral problem coming to the oven. I think it also eliminates a problem with the socket unless I am unlucky enough to have two good sockets in the bottom oven and two bad sockets in the top oven. I had attributed it to too much heat either from self cleaning or convection and the heat was migrating to the top of oven case and getting the top bulbs too hot. Any thoughts?

This snuck under the Moonbat radar and will do a fine job in your Easy-Bake Oven. I'm thinking about getting some of them to test battery backup units/UPS units of different wattages when I get back home. I have about 20 UPS units at home that I rescued from the trash and all they need are new batteries. I could sell them on eBay or Craigslist but I'd want to test them under load to prove to the buyer that the units are good. Oh yea, Easy-Bake Ovens are still produced and the new ones have a real heating element. ^_^

I have a similar problem with a GE Profile PT925sn4ss, this is an electric, double oven in a single space...heat up the top oven to about 450, the light goes out and won't turn on automatically when the oven door is opened. Turn the oven completely off and you can operate the oven light by pushing the oven light switch on, but the light still won't turn on by opening the door. Cool the oven down, and the light starts working normally again whenever the oven door is opened. Also noticed the top oven light goes out when the bottom oven is running at temps over 350. Turn the bottom oven off and let it cool down and the upper lights start working again. Other than the light issue, the oven works fine. Anybody else have this issue?

GE Techs are about as bright as the dead bulbs they replace. They have been coming to my house under warranty throughout my warranty period and I am on my fifth set of bulbs in my double oven. It's a high end stainless steel profile free standing stove double oven. The techs keep saying the bulbs. I said your bulbs all bulbs fail regardless. They keep replacing them but wait...The GE corporate consumer representative told me GE was aware of the bulb failures a couple of years ago. There was not enough getter material by the manufacturer for GE which made bulbs for many brands. I know it's the oven not the bulbs because this unit replaced the GE builder grade version of the same and never had bulb issues. They are sending me some special blue bulbs that have proper getter material wink 😉. And they both fail when not used so when you go for them twice a month maybe...they are both blown. I say relay arcing.

I have a Frigidaire oven and for the last month, I have gone through 2 GE Appliance bulbs and 2 Phillips Appliance bulbs (all clear 40W bulbs). I am going to try baking and broiling with the light off, and see if the bulbs last longer than a couple of weeks. I wonder if maybe the bulbs' construction has changed, since this is apparently not an isolated problem!

Maybe the bulbs are not making good contact in the socket. I'd turn
off the breaker to the oven to inspect the socket. The tab may need to
be lifted up and or burnished with a small piece of emery cloth.

Poor contact of the bulb and socket can cause bulbs to fail. make sure
the bulb is snug in the socket.

YMMV

I have a 20yo GE upper-oven that had the same symptoms but 123vac at the socket. Fix was to trip oven CB, remove bulb cover and bulb, remove 3x 1/4" hex screws holding top control panel on, remove 2x 1/4" hex screws inside oven on bulb socket flange, then got in behind upper panel and removed 2x electrical spring clips to back of ceramic socket and removed entire socket assembly down through upper oven.
Inspection of socket assembly revealed bulb cover not airtight and consequently moderate grease buildup in socket which I tried to clean out.
Inspection of wiring spring clips showed heavy grease build up on wider clip and I noticed the socket-side wide lug looked like it might have an arcing scorch mark and the lug was bent to be directly over air vent hole carrying hot air from inside the socket.
Cleaned spring clips, air holes, and lugs. Bent wide lug away from air vent path, reinstalled everything, and problem seems fixed. Same bulb has survived all of the holiday cooking and even a self-cleaning cycle.

I know this is an old thread, but we are now having this problem with a 20 year old dual wall oven. The lights in both ovens operate at the same time, so are both getting the same use. Of course, the upper oven gets more baking time than the lower one, and the upper light is the one that keeps burning out. The upper oven is a combination regular / convection oven. What I am wondering is if this is the case with any or most of the ovens that are having this problem. The fan that moves the air for convection baking seems a bit noisier than it did when new and maybe is vibrating a bit. The vibration could be causing the bulb filaments to break when the bulb is on and hot. As an experiment, we tried avoiding the convection mode for a few days, and the bulb lasted a longer, but still failed eventually. I have considered replacing the convection fan, but don't want to do that without being reasonably sure it will fix this very frustrating problem.

A new bulb is failing within a few _days_???!!!

What are you using for source of bulbs and have you checked voltages, etc.?

Don't have convection oven but the 40+ yo range here bulbs last many,
many months...we've been back to the farm for nearly 20 yr now and I
don't recall but changing the oven bulb once and that was just a few
months ago...I _may_ have done once sometime between, but long enough
ago I surely don't recall having done so.

Have you tried rough service and/or 220 volt bulbs?

Loose electrical connections in a bulb socket can cause a bulb to fail
prematurely. Since the connections are often riveted, there's no easy
repair so you'll need to replace it.
