What to do when the dryer won't heat in your Sears laundry center

When the laundry center dryer isn't getting hot, the culprit could be the timer or electronic control board that controls the heat. If your laundry center has an electric dryer, a broken heating element, failed thermostat, bad motor switch or voltage supply problem also could prevent the dryer from heating. If you have a gas dryer, a bad gas supply, failed gas valve coils, a bad thermostat or failed motor switch also can prevent the gas burner from heating.

On a laundry center that uses an electronic control board to control dryer operations, the control board typically signals an error code when the control detects a component failure that prevents the dryer from heating. Refer to the error code chart to help you determine the cause of the error code and heating failure. The dryer should resume heating once you correct the problem that caused the error code.

Common repair parts for the dryer in your Sears laundry center

• Door switch. The dryer door switch recognizes whether the door is open or closed. The dryer won't start unless the door switch senses that the dryer door is closed. The door switch also turns on and off the drum light on models with a light.
• Drive belt. The drive belt wraps around the dryer drum and connects to the drive motor pulley and the idler pulley. The idler pulley maintains the proper tension on the belt. The drive motor rotates the drive pulley, which in turn rotates the dryer drum.
• Electronic control board. The electronic control board is the circuit board that governs the timing and execution of functions in the dryer. It sends voltage to the drive motor and other components during the cycle. It senses the temperature in the drum and cycles the heating element on and off to maintain the proper temperature.
• High-limit safety thermostat. The high-limit safety thermostat shuts off the heat when the dryer overheats either because the operating thermostat fails or the heating element has a short circuit. The high-limit safety thermostat resets when the dryer cools.
