One possible issue could be a broken thermal fuse or thermostat. Before attempting any repairs or replacements on your dryer’s heating element, it’s important to confirm that it’s actually the cause of the problem. 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. Parts Dr 45.9K subscribers Subscribe 305K views 8 years ago If your dryer is not heating then you should test the heating element for continuity to see if it is good or bad. To test the heating element on a dryer, use a multimeter to measure the continuity of the element. 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. Do not let it continue to run and heat past this temperature. 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. Measure the temperature of the air coming out of the middle of the exhaust vent behind the 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. Some heating elements may require you to remove the existing thermostat from the. For cleaning after each load, be sure not to rinse the screen with water as wet lint is difficult to remove. Once you have the part, unplug the dryer, remove the back panel, remove the connections and install the new one. Close the lint screen and push it back into place. Open the lint screen if necessary, then remove the lint with your fingers. NOTE: Do not leave the thermal fuse bypassed following this temporary diagnostic test. Locate the lint screen at the top of the dryer or in the door opening and remove it. 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:
