roper dryer runs motor runs as soon as you set it, no need to push start button

[kellonnie]

when i turn the timer to cycle motor just starts but it doesnt tumble unless you manually start it, when push button is totally disconected it still does the same, hooked another motor same thing.. could this be a timer problem?

Model rex6634pq0

Bad idler maybe?

[kellonnie]

continues to do the same with belt disconnected. i am stumped

[kellonnie]

oh by manually start i mean spin the pulley.

[JWWebster]

Well if the rollers turn ok then maybe it is this ring:

tub ring/bearing


The belt ought to be connected like this by the way (click pic to make bigger)

[kellonnie]

the ring is good, belt is conected just as pictured. as soon as timer is set to any section on dial except off motor is running but its not getting the ump to go, so but can turn drum manually and it runs like a top. it does the same with start button totally disconected. its not the starter on the motor since i plugged in a new motor and still the same. door switch is good. i am clueless at this point,
i am really appreciating the suggestions thank you

[kellonnie]

hey do you think if the heating element grounded to itself could cause this, bout the only thing i didnt bother to check was the heating element

[JWWebster]

With belt removed does the motor turn ok by hand. If it seems tough to turn maybe you have the blower too tight.
The motor is 120 volt and on a diff circuit, heater would not affect that even if shorted.

[kellonnie]

motor turns smooth with belt off, thats what i thought about the heating element but couldnt hurt to ask. i am stumped on this. hate to tell the customers i just dont know, lol its such a basic unit, nothing fancy at all. plz any other ideas will be great. thank you

[JWWebster]

Maybe you got a dud motor. Send that one back and get another.

[kellonnie]

thought of that too, since i originally got it for another machine in my shop, i took it back to the shop put it in that machine and its good as gold.

[JWWebster]

Is it the same model motor for the dryer?
They ain't all the same although they might appear to be.
Your motor should be the old tried and true 279827 anythang else will not do.

[kellonnie]

yup exactly double and triple checked before i put it in the truck..

[JWWebster]

You must have a dud motor.

[kellonnie]

but if it was a dud it wouldnt work on the machine in the shop and do exactly the same as the motor on the wacked machine and that motor does, i would think, i am frustrated as hell with this machine now, lol
