Dryer will heat in auto-dry but will not heat in timed-dry. Coud it be the timer and how do I check for a bad timer?
The timer could be the issue if the contacts are not making to complete the heat circuit. To test the timer you will do a voltage test. You check from Black to Red wires on the timer. If you are getting 240 vac then the timer is faulty and would need to be replaced.
I'm troubleshooting my dryer for not heating. All thermostats check OK. It appears the timer may be bad. My question is; Is the heating element supposed to cycle on and off while drying?
Answer Hi Joe, yes the element is supposed to cycle on and off with the help of a cycling thermostat. There are several thermostats and a thermal fuse on your dryer. If any of those failed, it would interrupt power to the element. If the element works, check your vent for a blockage. Clogged vents keep a dryer from heating well and can eventually cause a hi-limit or thermal fuse failure. Also, you didn't mention it but is your drum turning? If not, you need to check your belt.
