Hi, thanks for using JustAnswer.com. Will the dryer shut off in the "Timed Dry" cycle, say like if you set it on 20 minutes? Also, may I please have your model number?
Are you able to check for power at the timer motor with a meter? Also, may I please have the model number?
Sorry for the delay...I had some issues I had to deal with tonight. Rest assured, you have not been "suckered" and I promise to see you through to the end of this repair for NO MORE CHARGES! Please do not click accept on any correspondence you may get pertaining to this problem. I might point out that it took you 16 hours to answer my post and it took me 6 hours to answer yours. We are both busy people....now, on to your question...
You will need to check for voltage to the timer motor terminals. You should see the wires that lead from the timer to the timer motor, unless your timer is sealed. Can you see any wires to the timer motor?
I believe the timer is at fault. There is nothing else it can be, especially if it will not shut off in the timed cycle. There is power to the timer motor 100% of the time in Timed Dry setting until the timer shuts off. If it will not shut off in the timed cycle, you have a bad timer.
