Drum does not turn but does heat up - Dryers

check for the operation of a small micro switch at the door hinge
if that is out of adjustment then the unit will not start

is the drum turning? if not you must replace the strap that turns the drum. if it is heating and the drum is not turning , that could cause a fire.

If did'nt remove ground wire could have shorted out the heating element.

If the heating element is getting very hot that means there is no air flow across it. If the drum doesn't turn then the blower is not turning causing the element to get very hot. Could be drum belt, drum rollers, or motor.

you have a bad motor,most likely.

Your model which we call the 417, is not usually easy to work on. The heating element is located behind the dryer drum. The drum has to be removed to change the element. There is a lot involved but given the cost of a stack unit the element and labor may be worth it.

either your heating element,hi-limit switch,cycling heat switch, thermistor,control panel, or you don't have 240 volts supplying the dryer,120volts will still let the drum turn or the timer count-down, its the way there wired

So,. basically your drum doesnt turn. SO your getting heat still even though the drum isnt turning. Is this right? Sounds strange??? Do you hear any humming noise when you push the start button? I need to know a little more about the problem because im kinda confused as how you decribed the problem. Iv never seen a dryer heat but the drum not spinning. especially your model dryer. Its electric heat right? because if the drum doesnt spin, maybe your motor is bad. and if your motor is bad, then your heating element wont heat up because the centrifical switch in the motor is not switching to complete the circuit to the heating element. So this is why im confused when you said" Dryer heats when knob turned but when "push button" pressed, drum doesnt run." Because your belt wraps around the motor pully and the motor is what makes the drum turn. Like i said, i never seen this model dryer heat with out the motor operating. So if you can give me some more info, ill do my best to help you out....Thanks!!!!

belt has come off or broken

The problem dosen't sound like the motor. Check to see if the drive belt is loose and slipping. This is the usual cause of the problem you describe. If not, the bearings for the drum may be going bad. The heating elements should turn off shortly if the drum stops so there is little danger of overheating.
