Customer Questions and Answers for Thermostat Heater by Whirlpool

Hello Jaymesh, This problem is not the fault of the dryer. It is a restriction in the exhaust ducting from the back of the dryer to outside atmosphere. Be aware that if the exhaust is restricted, the heat, lint, and moisture blow past the drum seals, right back into the dryer cabinet which should be drawing in room temperature air. In case you doubt my diagnosis, remove the duct from the rear of the dryer and start it on an automatic cycle and check on it in 5 to 10 minutes and you will see the timer has advanced. I am confident in this diagnosis since there is no difference in the cycles electrically and the difference is directly related to the moisture sensed during the cycle which stops the voltage to the timer motor.
