Which part of the part number really matters?

How might i get schematics/manual/parts?
(eg, I think I need a new fan)

You may find the electrical schematic pasted on one of the panels.

I've never see a fan go bad. Usually, it is the motor that turns the
fan. That should be easy enough to check by putting power to it.

Also, if he confirms it's the motor and pulls it out,
there could be the motor manufacturer's name and model
number on it. From that vintage furnace, they probably
used standard motors. From the nameplate model #
could probably find a replacement from many electric motor
suppliers a lot easier than identifying it via York model.

But one also has to wonder why anyone is still using
a 1965 vintage gas furnace. It's 120K BTUs, which suggests it's
for some serious heating. A new furnace would cut the fuel
bills by a LOT. And no matter how much better they made
them back then, I'd be worried about the condition of the
heat exchanger, safety, etc of a 50 year old furnace.

Look around inside, you should find a wiring diagram. (If there is a control board you will not find a schematic for it but they are usually fairly straight forward.) In heat mode there are typically two scenarios for turning on the fan. Either based on a temp sensor placed near the heat exchanger or a basic timer circuit. Both typically use a relay to handle the higher fan voltage/current. Sometimes you can hear the relay click on if you pay attention after gas ignition. Use a vom to check for power at the fan leads to figure out if you have a control problem or a bad fan motor. If the fan motor does not come on the gas should shutdown shortly due to an overtemp situation.

Hi,
If blower motor is older style PSC motor, first thing to check is
capacitor. Is the motor dead or humming or jerking trying to turn?
Is it getting power?

THanks for all the advice.

* Yes, the fan sometimes works, sometimes not. I'm hoping it merely got lose.

* Schematics inside unit - need to check. Didn't think of this. Much Obliged.

My uncle (80) keeps rebuilding the bathroom fans and he seems set on doing
same here. (but he's away for two months) I grew up in this house and have
some memory of where things are, but he is a total control freak (and a
fabuluous engineer) who basically has everything in his head and doesn't
explain.

I opened the furnace panel to get p/n and none were there. They might be in
the fan compartment. Nothing seems rusted but it seemed the panels needed a
lot more hitting than decades ago to slide them open. I'd like to fix it
before he comes back. I know he'll get upset I didn't let him. I don't like
burdening him. But I also don't want to break anything.

Thanks again.

THis is what I was hoping for. I found a lot of "universal" fan motors for
the bathroom use online. (But universal sometimes depends on which universe

(-.*)

)

Thanks again

Hi.
In that case when motor quits, check the power to the motor. I don't
know how old the unit is, is the fan easy to turn by hand? This is to
check motor shaft(bearings) is not binding or sticky. You can get
replacement motor from supply store easy.
