dryer hums and doesn't spin
 

I have a dryer that stop spining. The motor only hummed but don't spin. I
changed the motor #279827 and it still only hums (with or without the belt
attached). with it humming if I spin the blower wheel (without the belt) I
can get the motor to start spin but once I stop it it will not restart
without spining the blower wheel. I do notice that I don't need to push
the start button it will start hummig once I turn the large knob. ant
suggests?

That motor was mentioned on this page:
http://www.applianceaid.com/whirlpool-dryers.html
See if that's any help.

If the Start relay isn't closed, the motor shouldn't
do anything/

Did you try plugging the motor directly into an outlet?
Attach a cord with a plug on the end to the motor, use a few wirenuts
and plug it in. If it still hums, you got motor problems on BOTH
motors. If it spins normally, there is a wiring or switch problem.
Try this with out the belt first, then put on the belt and try again
(if the motor worked the first time).

If these are capacitor motors, the caps may be bad, if problem is the
motors themselves.

Something is not right. Just the fact that the motor starts without
pushing the start button tells me there a wiring problem someplace.
Remove the start switch and see if its stuck or shorted.

motors hum because they don't know the words
or
the capacitor or starting relay is bad. Possible bad phase winding.
or
Bearings are bad and require too much torque to get turning.

The Op did not specify if this is a 110 or 220v motor. I dont recall
ever hearing of a 220 motor in a dryer, but I suppose it's possible on
an electric dryer, and it could be running on 110 ????
Just a thought.

He posted on a seperate thread( same subject) one down from this one
its a gas dryer.

The thing is, she said she replaced the motor and the new one is doing
it too, even with the belt not attached. Parts list for that model
shows no separate capacitor or starting relay.

Either the new motor is dead in the same way as the old one, which
while not impossible is pushing coincidence, or there's a problem with
a part external to the motor, which likely would be the switch or
wiring.

I missed that post, but then it's a 110 motor.
Like I said earlier, hook the motor wires to a cord and plug it in.
If it works properly, there's a wiring problem. Otherwise motor(s)
are defective.
