The control knob on the dryer has ceased to move through the drying cycle. This happens in both the ‘Timed Dry’ cycle and the ‘Electric Sensor Dry’ cycle. As a result, the dryer does not automatically shut-off during these cycles. When the knob is manually turned to the ‘OFF’ position, the dryer shuts off. The heater does come on and clothes get dried.

Best way to check is with a meter.
Check to see if the timer motor is getting voltage (120 volts) when it should.
If yes and it is not advancing then the timer is shot.
If no, you have a problem elsewhere in the machine.

Be careful, there is 240 volts in areas of the control panel and it is lethal!!!

replace the timer. done deal!!! if you ohm out the motor on the timer, you will most liely get a reading, and be confused. replace the timer. tom

kayakcrzy is correct just checking it for resistance can be be confusing.
Timer motor's can short out part of the motor coil so it still has continuity but will not run OR the gears can strip Or the bearings can seize up.

That is why I suggested you check for voltage across the motor.
If it does not advance when it receives voltage it is shot regardless of the cause.

Replaced the timer, and seems to have fixed problem. Thank you very much for your help.

Good Job Asshish!!! I sometimes am a little harsh, as a technician running calls all day, I just know what to do, and don't have to whip my meter out, and make all kinds of useless checks. To me it was cut and dry. Glad you got it handled, and thank you for letting us know. Tom ********************************************
