My Whirlpool auto dry is not shutting off. Timer mode works fine. I've actually replaced this switch and the cycling thermostat. Now I'm at a dead end any ideas?
Thank you

Is the dryer heating up normally? A failure in the heating circuit can cause it to act this way?

Also, test the timer as we show here:

Yes, gets hot just fine.

Okay, let me know what you find after testing the timer.

I installed a brand new timer still didn't work

Which part numbers have you replaced?
