I've got a Frigidaire dryer. Model FDEB23RGS1. About six years old.

Lately, when run, it's made more noise than it used to, and would
sometimes just shut off mid-load for no apparant reason after about 30
minutes or so. I'd then have to wait a while and then it would run
for a while longer.

Now it only runs for a few seconds and then shuts off. Even if it's
only in the `Cool down' part of the section. The dryer definately
isn't overheating, at least not the heater part.

I've opened it up and cleaned it all out. The amount of lint was
scary -- obviously I should be doing that a lot more often.

I've disconnected the drive belt and tried to run just the motor and
blower, and it runs for a few seconds, then the pitch of the `hum'
gets higher and higher as the motor slows down and then it stops after
a few seconds. It sounds like it's working too hard and tripping
something. It won't run again for a while, but then it resets or
something and will run for a few more seconds.

Unplugged, I can turn the blower or the motor, but it seems to have
more resistance than it should -- but that's just my opinion, I've not
worked on these before. (Remember, the drum belt is disconnected at
this point, so I'm not moving the drum.) It turns easily enough by
hand, but the moment I stop turning it, it stops going.

The drum itself seems to turn easily enough. There's a good deal of
friction, especially in the front (where it just slides on foam and
plastic) but it doesn't seem unusual. (But I'm not certain.)

Back to the motor/blower -- it doesn't make any unusual noises when I
turn it by hand, but I'm guessing that the bearings on the motor or
maybe the blower are shot. But shouldn't I expect to hear something?
I guess it could also be that the brushes have popped out of place or
something?

I know how motors work, but my experience is with small DC can motors,
not 240 V AC motors, and guess my next step is to remove the motor and
blower assembly and see what I can find.

The dryer has a four prong plug. (It's an electric dryer, if that's
not obvious.) This wouldn't be three phase power, would it?

(Hmm, I do have the schematic. Duh. Looks like it's got L1, N and
L2, with 120 volts between L1 and N, and 120 V between N and L2. And
I guess the last plug is ground. Except that N is the ground,
according to the schematic. Eh?) Either way, it doesn't sound like
three cycle power, which simplifies things.

.... though when I look at the motor on the schematic, it looks like
it's got six lines coming in, from L1, L2, N and various switches. So
I'm not clear how I'd run it on the bench, or if it needs 120 volts or
220 volts. (But my guess is 240 volts.)

I'm guessing I won't easily be running it outside of the dryer.

Should the motor turn easily enough that I can spin it up with my hand
and it'll keep running after I do it?

Is it likely that the blower assembly has failed? (My guess is no,
that it's something in the motor, since there's a lot more in the
motor.)

Looks like the motor (131560100) is available online for $130-$160, or
I can get it on Ebay for $50 except that there it's called `Electrolux
Motor, Main with Pully'. Sounds like the same motor, but it's hard to
be sure. Or should I just remove the motor and blower and bring it to
somebody who's got actual experience here, rather than just my
theoretical knowledge?

(Is it even cost effective to repair a motor like this compared to
just replacing it? Especially if I can do it for $50+$20 shipping?
Perhaps I should just order the motor and be glad I think I can fix it
myself?

Doug McLaren,
Okay, brain. You don't like me, and I don't like you, but let's get through
this thing and then I can continue killing you with beer. --Homer

Doug,

I don't claim to be an expert, but all the dryers I've seen operate on
220 volts for the heating elements and the motor operates on 120 volts.
The motor should turn fairly free with no belt attached. The blower
attached to the motor pulls air outward from the drum. There is a
sensor or two there for safety reasons so the motor/elements will be cut
off should be belt break. And I believe those bearings in the motor are
sleeve bearings , not ball bearings. Try running the motor outside the
dryer with the blower off. If the motor gets warm and trips then I
would just get a new motor. Since the sensors are not that expensive,
you shouldn't overlook one of those being bad. Since you have the
schematic, you should be able to tell which sensor controls the motor.
Oiling the sleeve bearings in the motor would only be a temp solution if
they are going bad. Six years old -- I'd bet on the motor.

Doug McLaren,

Hi,

Cetainly -sounds- like the motor may be sour.

http://www.pcappliancerepair.com/cgi...00&bran d=WCI

Motor is 110-120 volts AC....looks like from M4 and M5 a test cord can
be attached directly to the motor to run it by it's self.

And after taking the motor out, it does say it's rated for 120 V, and
it's pretty obvious by looking at the wires where the power should go.

Actually, oiling the bearing/bushings made a huge improvement on how
easy the motor was to turn manually. I've oiled it up and will go
ahead and put it back in the dryer and see how it goes. I'll also
order a new motor -- at $70, I imagine I'm getting off cheap.

(The bearings/bushings don't look to be replacable.)

| Six years old -- I'd bet on the motor.

Good bet

Thanks!

Basically, the motor uses a centrifigal switch - when the motor gets to a
certain RPM, the DPDT relay is activated. When this happens, the start
windings change from NC to NO, and the 240VAC is switched from NO to NC via
M1 and M2.

What this means is that when the motor spins up, the contacts in the
centrifugal switch on the motor switch on the heating elements - no spin, no
heat.

As far as your symptoms, definately shot bearings in your motor.
