For Whirlpool Thermostat, Control (Part Number: AP4039476)

The dryer works fine when you use the timer but when you use the auto (more dry - less dry) function the dryer shuts off before the clothes are dry. From looking at your site I think it might be the cycling thermostat but it could also be the thermal fuses. What do you think it could be? Thanks for your help.

ANSWER Hello Tom, This can only be caused by the improper programming of the unit or a bad cycling thermostat. Let me clarify before you get mad at me. The unit is designed to provide a longer dry cycle on the automatic cycle. When the cycling thermostat opens, the timer motor advances. If you put in a load of wet towels and put it on less dry, they will not be dry at the end of the cycle because the timer times out too quickly. If the cycling thermostat is open, the timer will advance just like it has been programmed for a timed dry as the voltage will be applied to the timer motor as long as the unit is running. The thing about the cycling thermostat being open is unlikely as this will also cause no heat. The only thing that makes sense to me is if the cycling thermostat is out of tolerance and is opening at too cool a temperature and the voltage is being applied to the timer motor too often, therefore timing out the cycle. The problem cannot be the thermal fuse because if the thermal fuse is open, the unit will not run at all.
