I Need A Strong Plastic Glue For My Broken AC Fan. Anyone Know of One?
Pamela
fan on my air conditioner? My air conditioner finally broke down, and
after taking it apart I found that the problem is the plastc shaft of
the blower fan that broke in 2 spots. I checked Fedders.com to try to
locate a new fan, but had no luck as I suppose since the air conditioner
is so old, they don't make the parts anymore. Does anyone know of a
super glue that will hold? Or does anyone know of a parts supply house
that would have a new fan for sale? The AC is a Fedders, made in
September1979, 7,000 BTU, model #ALR07F2HD
Here is a scan of the fan and broken part. Thanks! Pam.

Sorry but no glue is going to hold and the cost of this type of A/C
makes them throw-a-ways.

Super Glue is actuallythe best glue for plastics. I would replace the fan
though. You can get a replacement I am sure. Go here to try and find it
www.grainger.com
If you have a Grainger Warehouse near you, you can take the old one in and they
will match it up for you with one that will work. Fans are based on rotation,
pitch and CCF at given RPMs as well as shaft size. Also look in the yellow
pages for Maintenance Supply distribitors and you should be OK.

shaft motor then you can get a new (it looks like an E clip to me) at
just about any small type auto parts store, they take out a metal box
and match it up with what you got... if you need a new motor, just look
in the yellow pages for Electric Motors and take it to one of the shops
and they can match it up.. if not they can tell you where to go to get
what you need... the only thing i have used two part epoxy glue on was
the plastic shell on one of our old window units years ago... and it
held up pretty good..

the fan) makes it impossible for ANY gluing operation to succeed. The glue
would only be holding the ends of the fragments of the shattered hub. If it
were mine I would drill it out and epoxy in a plastic or steel bushing to
replace the plastic, and maybe attach it to the motor shaft with a set
screw. This presumes there is enough material in the fan blade to hold the
bushing.
The thing is, this unit is nearly 25 years old, and is probably half as
efficient as a modern one. It is likely to fail due to lost refrigerant in
the near future (remarkable that it hasn't already). If it were mine I
would fix it because I can. Maybe you have a friend with machinist talents
who could do something (it's fun to fool around this way) but if not, maybe
shop for a new air conditioner.

The good news is, I bought a welding outfit for welding any and all plastics. I
bought it from Harbor Freight Tools.
The bad new is, I haven't used it yet, so I don't know if or how well it works.

It seems to me from your picture that it is the fan blade that is
broken, even though it is at the center near where the shaft of the
motor goes. You can glue the parts back in place with super glue or
plastic weld or pc-70. If you use a heavy glue put it on evenly
around the center so it doesn't unbalance the fan.

First of all, No on the glue.
Meaning...no, dont even try to glue it.

They didnt make the fan that IS on there...
However, the fan is availible.

A super glue? There is only one, and no, it will not hold that type of
plastic, nor will any glue hold up for long due to the stresses that are
placed on teh fan hub at startup.
> Or does anyone know of a parts supply house
> that would have a new fan for sale?
Yes...but..
You need to know the following.
Outside slinger size
fan diameter...will be smaller than the slinger size..obviously.
fan blade pitch
bore size
number of blades..(ok..no brainer)
rotation
The reason you need all that, is that no one supply center keeps all the
fans in stock, and might have to order one...
Expect between $40 to $75 for a new one...if you can find the CORRECT one
for less, consider it a bargan.
Now..based on that...spend the extra $25 and get a new unit.
If you figure the time you will spend looking for a new fan, the time spent
taking it apart, the time spent putting it back together...well...I dont
know what your time is worth, but on a total compent replacement that is
that cheap, and todays units being more efficient, it would behoove you not
to get a new unit.

BTW, I've never gotten super glue to stick anything together, not even
my fingers, but it seems a lot of people like it.
And...You probably don't have to fully reassemble it to test it for a
while. And I'm still not sure what clamps the blade to the shaft.
you can also put some glues on the shaft and glue the blade to the
shaft. Just get it on the right distance before it sets. I guess
that leaves out superglue which sets on contact?? I like 5 minute
epoxy in the double syringe. I like 5-minute because I don't have to
hold it long before it sets. If you are gluing it on to the shaft,
you won't have to hold it at all, so you can use 30 minute epoxy -- I
think they still sell that. I've found the stuff keeps for years, but
it would take me years to use the rest of 30-minute.
My other favorite glues are Elmer's? contact cement in the red tube
(not white) which is good for things that bend. PC-70 which is good
for things that you think can't be glued or which need to fill in
space. And ambroid cement, sold pretty much only at model stores.
It's good because it dries quickly, sticks to most things, and can be
broken later if needed. Of these three only PC-70 comes in two
containers. Most of the time these 3 and the 5-minute epoxy are
enough.

If they're like the Grainger here, they won't deal with a walk-in,
especially with a name like "Pamela".

Well...HER name wont matter, but the name of the company she owns and can be
verified will.
The Graingers here have a strong policy of NOT selling to off the street
customers. You must open an account, and have that account verified before
any sales take place. Same with Johnstone, Ferguson, VA...etc. I have seen
Johnstone sell one walk in customer a case of filters, at retail....but
thats it. At least once a week, someone will walk into one of my suppliers
when I am in, and the counter people are nice about it, but they suggest
that if they want anything from the stockroom, they talk to one of the many
contractors waiting that have accounts and see if we will do the job for
them.

Not only that but any graingers I have gone to couldn't match up a motor let
alone a fan blade. all they can ask is " what is the part number you want? "

the surrounding area so it will stick, (Knock the shine off it).
Rough sandpaper is great or even the edge of a kitchen knife just
scratch it up deep, the deeper the better. Spread the epoxy on and do
both sides of the break if possible. This stuff can run after a while
as it won't harden for hours so check it every so often the 1st 2
hours or so and be careful how you position the part to begin with to
dry. Let it sit the entire 24 hours or more before assembly. You
can sand off some to make it look better after or paint as desired.
Theres lots of easier to use epoxies out there but J&B is the only one
I use as its truly tough stuff though the convenient double tubes with
the syringe are easier to use.

Don't use super glue because it's not very good for plastics, and
Loctite warns of this even for its Plastix super glue kit made
especially for plastics.
Try to find out what kind of plastic it's made of by exposing it to a
solvent like lacquer thinner, carburetor spray, or acetone, and if any
of them dissolve it, use it to make the repair. Otherwise the best
repair is generally made by melting the plastic together with a
soldering iron (clean the tip first).
Plastics that are best repaired by gluing include ABS, styrene, PVC,
and polycarbonate, but I wouldn't expect a fan to be made of any of
these, except for the latter.
Plastics that are best repaired by melting them include nylon, derlin,
polypropylene, and polyethylene. Nylon is the most likely candidate
here.

If the plastic will dissolve with lacquer thinner, acetone, or
carburetor spray, it's best to solvent weld it, but if those chemicals
don't affect it, heat welding is about the only good repair. The
easiest plastics to heat weld are nylon, derlin, polypropylene, and
polycarbonate, while polyethylene seems to be the worst. And while
polycarbonate can be solvent welded (methylene chloride, that is,
nasty paint remover, is usually best), the surfaces turn to a white
powder if a mistake is made, so heat welding is often better.

And want to use the worst possible product for the job.
J.B. Weld is just epoxy, and epoxy rarely works well on plastics,
except for porous ones, like styrofoam, or hard, brittle ones, like
Bakelite and polyester.
The only common products that work are solvents (lacquer thinner,
carburetor spray, paint remover), but only for things like PVC, ABS,
and polycarbonate, and, for plastics not affected by solvents, like
nylon and polyethylene, heat welding with a soldering iron.

feedback!! After reading your posts I'm inclined to just junk the AC. I
feel so awful about the idea of throwing away a perfectly good item only
because of one small broken plastic piece. I mean, it sounds so wasteful
to me, like taking your car to the junkyard only because it has a flat
tire.:) I would be more inclined to try some of your suggestions to
repair the unit, but after hearing some of you say that an old model
like that uses much more energy to run than a newer one, well that is
definitely the deciding factor in my choice to just "junk it." I had no
idea that old air conditioners were such energy hogs!! Out of
curiosity, can anyone who knows electrical usage costs give me a rough
estimate of the difference in savings of running my old 1979 7,000 btu
AC for 5 hours a day during June, July & August, versus a 2003 7,000 btu
AC??

New models have EER ratings, but yours is too old to find that info.
Look at the name plate for the AMP rating. multiply that by 120 to get the
watts. I looked at the spec of a new 8,000 Btu model and it will draw 7
Amps or 840 watts. If you pay 10¢ per kW/hour, it will cost you 8.4¢ per
hour when the compressor is running.
If your older model draws 12 amps, or 1440 watts, it will cost you 14.4¢ to
run for the same amount of time.

pieces, put them together, then sprinkle it with baking soda... makes one
of the strongest joints I know of... also great for filling in gaps where
pieces don't fit good, too. but in this case, I still wouldn't recommend
fixing the fan because of balancing problems. the fan blades would not be

I've never had an instance where super glue worked better on thermal
plastic than solvent welding or heat welding, including when MEK
primer was used with the super glue. I sometimes had to repair nylon
gears that I couldn't buy, including replacing lost teeth, and the
only thing that held up was heat welding. In the case of a nylon fan
or impeller, I wouldn't trust anything else, and nylon is probably the
easiest plastic to weld.
