![]() NOTE: If you are not completely confident in your technical ability to safely conduct this test, then I recommend calling a service technician to diagnose and repair the dryer. NOTE: Be sure to replace the thermal fuse before running the dryer beyond this temporary component test. If the dryer is cycling properly with the vent hose disconnected, then the likely cause of your thermal fuse blowing is the vent duct system to the outside of the home. Locate the heating element’s metal casing. Unscrew the back panel of the dryer (some models may require removal of the front panel and dryer drum). Follow these steps to troubleshoot the heating element: Disconnect the power to the dryer. Do not let it continue to run and heat past this temperature. The heating element is located at the back of the dryer, inside a metal casing. NOTE: Stop the dryer if it heats past 180 degrees. You could also have a heating element that is shorted to the cabinet and heating constantly. If the dryer heats up way past 150 degrees, then you will likely need to replace the operating thermostat that is right beside the thermal fuse. The dryer should continue to cycle between about 130 to 150 degrees. The heating element should then shut off until the temperature decreases 15 to 20 degrees. The dryer should heat up to about 150 degrees. ![]() if it still does not work then you missed something. One of the most common problems that homeowners face with their electric dryers is when they have a dryer not heating up. Then look for supply, fuses, switch, thermostat, safety limit temperature cutout etc Then test each and every bit. The high-limit thermostat is a commonly replaced. Measure the temperature of the air coming out of the middle of the exhaust vent behind the dryer. 1 I would follow the wires to and from the heater element - a diagram would help, but if you know what you are doing it’s nit absolutely necessary. Dryer isn’t heating or takes too long to dry This video demonstrates how to test a high-limit thermostat on a gas or electric dryer. Start the dryer on a timed cycle with high heat. Position the dryer so that you can measure the temperature of the exhaust air from the middle of the vent in the back of the dryer with an accurate thermometer. ![]() Pull the flexible exhaust vent hose off of the back of the dryer so that it will vent directly into the laundry room. Reassemble the dryer and plug it back in.įill the dryer with a medium load of wet laundry.Ĭlean the lint screen and make sure it is properly in place in the lint screen housing. The thermal fuse is an essential safety component that must normally be in place to safely run the dryer. NOTE: Do not leave the thermal fuse bypassed following this temporary diagnostic test. Use electrical tape to properly insulate the connection and avoid contact of bare wire contacts with the dryer cabinet. Temporarily tape the two wires that go to the thermal fuse together to essentially "bypass" or "jump" the thermal fuse. Unplug the dryer to disconnect electrical power. If you did not find any obvious problems in the exhaust vent system to the outside of the home, then I recommend conducting the following test:īefore replacing the thermal fuse again, try these steps: ![]()
