gas fireplace won't start-up - pilot is lit

Hello all -

first post on this forum, so please excuse any newbie errors...

I have a gas fireplace at home that I haven't used in a couple of
years. I had turned the pilot off after I used it last. I tried to
start it back up yesterday, and the pilot started right up. I have a
wall switch that controls the gas flow and turns the fireplace on.
When I try to flip the switch to turn the fireplace on, it does
nothing 9 times out of 10. Occassionally the flames will come and
stay lit for a couple of minutes before going out again, and then
nothing. I don't smell any gas when the fireplace switch is on but
the flame isn't present. Not sure where to look to try and debug this
issue... any helpful pointers would be greatly appreciated!

Merry Christmas!

Funny thing......I just went through a very similar process with our
gas log set today.

I tried to light the pilot & it would light but not stay lit

So.... I turned off everything.....the electrical switch on the log
set (my set doens't have a wall switch), the manual valve on the log
set to "off" postion and the recessed gas cock on the side of the
fireplace.

I did the start up process....open gas cock, turn manual valve to
"pilot" & depress, light pilot and hold knob in for ~2 minutes, turn
manual valve to "on".

Pliot stayed lit......flipped electrical switch to "on" and the log
set fired up & has stayed burning for a few hours so far.

I have no idea why the pilot wouldn't stay lit but turning everything
off seems to have fixed it. ????

Give the "total shutdown and wait a few minutes before a re-start"
a try.

cheers

Does it have a thermocouple on the pilot a maybe 2" round metal piece
with a wire on it going to a gas valve, that might be bad I used a
propane torch to heat one up once, its probably a standard item even
some place like Sears might have for cheap. But I am guessing and dont
know if what I recomend is safe.

First of all, need to know what kind of "fireplace" it is:
1. Direct vent or natural vent
2. Free standing, zero clearance or masonry insert
3. Vented or unvented gas log.
4. ODS or thermocouple/thermopile
The above combinations can be used in a number of ways.

Thermocouple/thermopile assemblies have 2 separate circuits powered by
the their respective devices.
Thermocouple = 20 millivolts (+/-)
Thermopile = 750 millivolts (+/-)
If the pilot lights and stays lit, the problem isn't with the pilot circuit.
If the main burner doesn't light, the problem is in the main burner circuit.
Some units have more than 1 switch controlling them.
The supplied switches on the units are notoriously unreliable.
The gas valve generally has connections for the main burner labeled TH,
TP, and TH/TP. The main burner is operated by a switch that makes a
circuit between the TH and TH/TP connections.
Is there a remote installed on the fireplace? If so, there is usually a
switch on it labeled on/remote/ off. If you move the switch to on and
the main burner lights, check the batteries in both the remote and the
receiver. If it doesn't light, check the other switches/controls
connected to the above connections.

The above procedure assumes the control valve is in the "ON" position
and not in "PILOT".

These gas log sets have to be cleaned every so often. Dust gets in the pilot
hole and the symptoms you describe happen.

I had two phone calls this week from people with gas fire places and heaters and
both had the same problem. DIRT!!!

Happy new year to all!

I checked the fireplace and couldn't figure out the make - the card
that came with it says XDVR-38RMN, but I couldn't find anything based
on that description in my Google search. I did see a circuit diagram
that mentions Thermopile. It's a masonry insert.

The pilot does light easily and stays lit, so as you suggested, that's
not where the issue is. I did clean everything out and then tried to
get the fireplace going again to no avail... There is NO remote with
the fireplace - just the wall switch. I checked all the circuit
breakers and saw no issue there. When I flip the wall switch, nothing
happens. I don't smell gas when I flip the switch... Would a bad
thermopile result in these symptoms?

Appreciate any additional pointers you may be able to offer.

Thanks!

If the pilot is lit, make sure the gas valve control is in the "ON"
position. Check around the gas valve area for an "off/on" rocker switch.
If found, place it in the ON position. If the burner lights, the problem
is in the wiring to the wall switch.
There wouldn't be any issue with circuit breakers. The wall switch
connects only to the gas valve. If you have a VOM or a continuity
tester, disconnect the wires

Go to the gas valve, look for three terminals. One will be marked TH, one
TH-TP, and one TP. When the TH and the TH-TP are connected, the fire lights
if the gas valve is in the on position and you have a pilot. There is no
power here, so you can jump with a paper clip. But when you do *** THE FIRE
WILL COME ON ***, so be careful and be prepared. If it does light, then the
problem is in your wiring to the wall switch. If is does not come on, the
problem is in the gas valve. The wiring is the likely culprit.

I had the EXACT same problem. What appeared to be a good pilot was giving
me 540 millivolts at the terminals, but when I turned the valve from pilot
to on, the fireplace would not come on. A last ditch effort was to get a
new can of air, with the little straw that lets you direct the air. I
place the straw right into the two little holes on both sides of the
pilot, and blew them out.Next I blew out all of the holesin the burner,
just in case there was a spider nest. Lastly, I cleaned my tp terminals.
The resulting pilot light now looks more like an F-14 in zone 5
afterburner, shooting straight out, not out and up, and I could hear
little crackles like whatever had been blocking it were burning up now.
And when I turned the knob to on, I could hear the gas valve open. So it
works for another year!

The pilot light flame must hit the thermocouple correctly, or the voltage the thermocouple generates may not be enough to operate the main gas valve, while it is enough to keep the pilot light lit. Try adjusting the pilot light so that it more directly hits the thermocouple, check for clogged holes in the gas supply for the pilot as the previous poster found to be his problem.

Hi,
Main valve is controlled by 24V control voltage, not by thermocouple.
thermocouple's job is to keep the pilot on.

Maybe a thermocouple's....but a thermopile generates the energy to open
the gas valve. Once you turn the valve to pilot and ignite it, the pilot
is on. If the pilot blows out for some reason, the thermopile senses the
loss of heat and shuts the pilot valve down. Which is why if you turn the
pilot on, push the knob in and ignite it....and you don't let the
thermopile heat up enough? The pilot goes out.

Thanks for the advice. The paperclip trick worked for me, so I know its
not the gas valve. I then disconnected the wall switch and connected the
wires, it did not light.

So I assume from this the problem is the wiring between the switch and the
unit? That is a major bummer if true as all of this wiring is in the walls
and seems to be nailed to the studs as I can't pull it loose.

Open to any suggestions.

Paperclip test worked.

Put a meter between the two screws that were successful in the paperclip
test and reading was 260.

Any advice is appreciated from here. I tried to just manually connect the
two wires that were at the wall switch and that did not work.

Hi,
If the FP has removable sealed glass front, there is a interlock switch.
Just like gas furnace has cover interlock switch. Checked that
switch?

I worked on a natural gas fireplace, last year. The HO
kept insisting that I had to change the batteries. This
made no sense to me. I finally found a plastic box under
the FP which had four AA cell. Change the batteries, and
it came back to life.

Probably millivolts , since the OP mentioned a thermopile . I have a
customer down in Memphis that is having the same type of problem with a
floor furnace , but intermittent . He has whole-house forced air too so he's

millivolts. It was 220 this morning. Tested the TP terminals. From what I
am gathering this means I need a new thermopile?

I would. Should be above 300 *at* the thermostat. Replacement is the
cheapest, quick fix/test option. Hopefully the gas valve is not on
its way out, either.

I'm dealing with a similar problem. Bought the house this summer, and got the pilot light lit when fall came. Flipped on the wall switch, took a minute or two and then fired up. Try to turn the wall switch on other days, wait several minutes, nothing happens. Turn off the gas, relight the pilot light, flip the wall switch on and again it fires up after a minute or two. Then I still have the same problem on other days where it won't fire. After reading these posts, I had seen a little box under the fireplace so I pulled that out, it's a remote start which seems to work fine. Turns on turns off no problem. So I turned it on with the remote, flipped on the wall switch, turned off the remote and it stayed lit. Assuming there's a problem with the wiring in the wall switch? Any thoughts would be appreciated.

Trace it back to low voltage past the switch. Check the transformer
maybe? Folks here can help -- provide the model number and/or a URL
to the exact unit.

Try bypassing the wall switch with a clip lead or by shorting out/connecting the two terminals at the switch. Spiders have been known to live inside switches, especially if they were idle for 2+ years.

Gas fire places are really simple. Usually with a wall switch there is a
short. Find the two wires going to the switch and cut them and connect
them. It's only 750 millivolts at best, so you are not going to
electrocute yourself! If that doesn't work, it's either the
thermocoupler or the oxygen thingie on the back/ I know that is not
very technical, but there is an oxygen sensor that makes sure you don't
die of carbon monoxide poison. Go to to Home Depot, Lowes, or Staples
and get a can of air. Find the hole and clean it out. I had a neighbor
who hadn't used his fireplace in a coupla years and he told me I saved him
$75 with a ten cent blast of air. Dust and soot get in there. Hope that
helps!

I had that problem on one of my FP. I traced the wires and there was a
poor crimping job on one feeding the 24V AC power to maan valve
solenoid. I have two wall switches for the FP, one for on/off, one for
fan on/off(I leave it on always). Fan is controlled by thermo. switch
mounted on the fire box wall usually.

If your pilot light is lit, but you can't get the logs to light it may be your micro switch. My switch was located near my igniter button. Just put your gas log switch (light switch) in the on position. Take the two wires off the micro switch and touch them together. If the gas logs light you have found your problem! Don't worry, touching the wires together will not give you a shock.

I'm having a similar problem. Asking the forum for help with my
Heatilator natural gas fireplace. I went to start it up this year and I
could get the pilot lite but when I went to turn on the main wall switch,
nothing with the main burner. I went through all the trouble shooting and
the thermopile/pilot was borderline so I replaced the complete assembly.
The numbers are much better now but still the main burner won't trip on
when I flipped the switch. I also tried shorting the wires together
thinking the switch was bad but nothing. What voltage should the wall
switch have at it? I'm not sure what voltage the valve operates off of
and Heatilator support is no help.

Thoughts?

My recent problem is pilot light is lit but when I turn on the switch to light up fireplace it doesn't light up. So, I used a paper clip to jump it at the connections and after a while it lit up. So I conect the wires back and it is now working like it's supposed to. My question is, what is the problem, why didn't it turn on at first before jumping? Is it a possible bad wire or gas valve. Remember I thought it was the wire..but when I reconnected everything back and turn the switch on it worked.

Not holding down the igniter long enough before turning the switch?

Air in the gas line - purge it out... or low gas pressure.

Clean the burner orifices, etc. YMMV

I'm saying if the wall switch is on, holding the igniter down longer
allows the gas to flow before you turn on the valve switch. I'm
confused now. Was the gas line ever disconnected to allow air in the
line or is it low gas pressure...

Start a new thread with your brand and model number for the gas
fireplace appliance. Instead of picking up mid-stream. So many
variables as to your problem.

I remain confused.

I just went through this today. Turns out the gas line to the pilot flame was blocked. There was an orifice on the end of the line near the thermocouple that was corroded and blocked. Cleaning this up so proper amount of gas could flow and provide proper pilot flames fixed it.

The gas line is lower pressure. Purge the air out, connect the line
and try lighting again. Make sure you have tools ready.

CAUTION -- DANGER Do not have any sparks or fire flames around. With
the line disconnected turn on the gas until you smell it, turn it off
and _immediately_ connect the gas line. Then try starting the
fireplace again. What you are doing is purging the air from the line.

Changing a gas water heater, I had to purge the air out, before it
would fire.

DO BE CAREFUL.

Thanks...it is working now. Last year I had the same problem. I need to find out how air is getting into the system. The people at the house have not had any reason why this is happening. Last year it did the same it hesitated to light up. Last year I replaced the switch. This year I had to jump it at the valve connections. Once it lit I removed jump wires and connected back all wires. I then flipped switch and it worked..the only thing I can say is somehow air got into system. I got repair any thing cause it is working now. I will inquire with gas company about what is causing this. Thanks all for your input.

Air _should_ not be getting into the gas line; if properly sealed,
otherwise it seems gas would also be leaking out, no? Are you turning
off the gas valve after winter?

Maybe contact your gas utility company and have them inspect the
lines. In my area they provide a free service to connect gas
appliances and inspect them.

EASY FIX! - Maybe, moved into our 10 yr old house 2 yrs ago. Our Heatolator
always had issues lighting, flipping the switch many times before lighting.
Had a guy come out last yr who charged $100 to clean everything, worked a
little better for a week or so then back to same old problem..recently I
started poking around under bottom where components are located with a
flashlight I spotted wire leading off to what turned out to be a battery PAC
with 2 D cells in it.. they were very corroded. I remove the two batteries
clean the connections put two fresh batteries in and Wala the fireplace starts
up every time on the first throw out the switch. This would be for gas
fireplaces with an automatic pilot light meaning that you do not have to get
down and light the pilot light yourself it is controlled by the wall switch.
I assume these batteries have something to do with the electronic ignition,
either way it's fixed my problem. Nobody anywhere ever mentions this when
talking about fixing these fireplaces

Our fireplace has been working fine then last night when I turned the knob off like normal I went too far and the pilot light went out. Went to restart it and the pilot will light but as soon as I go to allow flow of gas to the logs it goes out and cuts off. We just had it served and cleaned so I don't think it is dirty or blocked in any way. Tried turning the gas on to the logs and lighting it with a match and nothing, almost as if the logs are not getting any gas. Any suggestions.

Guys, I'm have a similar issue. Ventless Real-Fyre G9-2 unit with wall mounted remote. Pilot stays on and I can manually turn the FP on with the on turn knob on the unit but remote box will not work. I bypassed the wall connection with a brand new sky-tech remote box and connected directly to the TP TH / TH connectors but when I move the Skytech box to the on position it still does not ignite. So I bypassed the wires in the wall thinking maybe mice and connected directly to unit with new remote box but nothing. Again, manual operations work fine. I'm stumped.

If you turn it on manually, can you turn it off from the remote?

Similar problem. Pilot is lit and the switch which has on / off / remote works for a while, then I can not turn it on with the switch or remote.

I had to replace the previous switch a because I could almost never get it to work. The connector on the new switch did not match the old one so I had to splice the wire from the fireplace to the new receiver together. When it is not working and I switch it from OFF to ON and it does not light, if I disconnect one of the splices and then reconnect it lights no problem. Also, I can touch the two wires from the fire place together and it lights no problem every time so I am pretty sure it is not anything from the wire back. Any thoughts?

It could a lose connection or bad wire. My fireplace was coming on intermittently. So I went to look at the wiring and lifted one of the wires and it came right on. So I knew that the wire was either bad or it was lose connection. It turned out being a lose connect . Works great now. So anyway check your wiring fist make sure everything is connected and not lose. It can be as simple as that.

HELP PLEASE!

I have a Heatmaster Vent-Free Gas Log set. It is operated manually (no wall/remote switch) I can get the Pilot to light and stay lighted but when I turn the valve to "ON" the burner does not light. I have cleaned the double burner and pilot area with compressed air. What can I do next?? Thanks for any suggestions.

Most gas appliances that rely on a pilot light have a thermocouple that's
in the pilot flame and connected to the gas valve. The thermocouple, when
hot, generates a small electric current that the gas valve needs to open
to supply gas to the burners.The reasons why are obvious. Probably a
bad thermocouple, it's a common failure.

You may have air in the gas line and it needs to be purged. Disconnect
the line, open the valve until you smell gas. Close the valve,
connect the line and try again.

Don't hurt yourself!

Hello folks,

I, too, had an issue with the wall thermostat intermittently operating the thermopile powered gas log set. The 18 gauge thermostat wire run is about 25' which is a long run for a 750mV thermopile. I replaced thermopile and it did fine for a while. Checked various sites for TESTING with a 1.5volt battery and the valve opened every single time. DO NOT leave it hooked up like that as all safety devices are defeated. Got me thinking about hooking up batteries in series doubling voltage, could it work with thermopiles? I gave it a shot and hooked two 750mV thermopiles in series and stacked them in pilot flame until my multimeter gave highest voltage. Works like a champ!! I have 1300mV idle and it drops down to an acceptable 700mV when gas valve opened loading the electrical system. Keep in mind that this does not affect safety in that should the flame go out the pilot thermocouple and the main gas valve thermopile voltage will drop to zero and the valve will not open. Just sharing what worked for me.

I had an interesting experience once. I was helping a friend put in a
new, expensive LG dryer. We went to HD to get the necessary fittings.
After installing it, it would not light. We wound up making a warranty
claim. The service guy came and guess what it turned out to be?
A nickle or dime, I forget which, was inside the valve or fitting we
bought! Someone had done it as a prank at HD and we never thought to
look inside for an obstruction.

I am experiencing a similar problem with my Majestic gas fireplace.
I have checked all the recommended voltages and they are all within spec.
My problem is intermittent.
Pilot is lit and bright, but no flame when the thermostadt is on.
Normally I here a small click from the fireplace when the thermostadt is turned up, but nothing when it does not light.
Also, for some reason, pushing and holding the ignighter in for several seconds often turns the flame on ??
And shorting the terminals with a paper clip also turns it on.
I have read that resistance can build up within the system but I'm unsure if that means in the wiring and thermostadt or the gas line ?
Any Ideas??
Thanks

Replace your thermocouple/thermopile. If it's bad, the pilot won't generate
enough juice to open the gas valve.
