old dehumidifier

[[email protected]]

Am looking for online sources for parts, specifically the units'
120v fan-motor. Can't find any model number for this
Westinghouse relic. The compressor seems to cool the coils OK
and will frost-over but the fan just won't go. The fan is approx
9in dia. w. 3.25 to 3.5in dia. motor. Just trying to get the old
thing going again. Motor does get voltage.
I did a google search and found nothing even remotely close.

Try http://www.grainger.com/Grainger/wwg/start.shtml
You'll have to do some disassembly and measuring, but you can probably find
the fan motor, and do the whole deal online.
good luck,

Thanks for the link. I just search thru their site and did find
'close, but no cigar'. They have 3 1/3in diameter HVAC motors
used for dehumidifiers but their mounting arrangement seems to
be different that what I've got. Their Morrill motors appear the
closest to this one. This one has a black cast iron body housing
like some of the ones they have. The 2 tapped mounting holes are
on the stator body diameter that is used to fasten the motor to
the bracket. The other half of the cast iron houses the rotating
inner part of the motor. This motor, being so old, probably
might be better replaced with a more modern one if it could be
adapted to fit. I was hoping to find a direct replacement unit
with the same mounting, etc. The search continues..... Thanks again.

You will probably have to make do by drilling new holes or somehow adjusting
the mounting. I doubt you're going to find an exact replacement for an old
dehumidifier.

Is it a brush motor, and if so, can you check them? Might be a simple
fix. I've had some where a brush just got stuck and a little poking
around on it had it working again for several more years. Other times, a
replacement is required.

It would not be a brush type motor but but a single phase induction motor
or perhaps a capacitor run induction motor.

However, there might be a blown thermal fuse inside or a bad connection
so it is worth checking.

By his description, it's a unit bearing induction motor. Those things would
run for centuries if a spike didn't burn them out. Sam is right, he's gonna
have to bend up a little sheet metal or drill a couple of holes to make
today's motors fit.

In fact, I have one that will probably need that treatment as well. I've
upgraded the motor's sleeve bearings to ball bearings as a result of
bearing failure but since the fit isn't perfect, the thing makes a
terrible racket, though I suspect it would continue to run forever.

I have no clue as to how to even get this motor apart. The fan
spins so the bearing appears to be OK. There is only one
discernible marking, a number Y-13963, engraved into the the
cast iron housing. I wonder if this motor was pressed together
during assembly. There is a small business kind of guy a few
towns away who has been in the business of rewinding motors for
eons. Maybe I'll get out there with this motor and have him take
a look at it.
