How to Test the Heater Coil on an Electric Dryer

Save

A dryer can stop heating the air from the blower for several reasons. The failed breaker in the panel box, a damaged dryer cord, a blown thermal fuse or a heating element that no longer works could all be the culprit. Testing the dryer's heating element and determining if the cause of your heating loss is a failure of the element requires you to take apart the dryer and test for continuity on the element.

Things You'll Need

  • Phillips or slotted screwdriver
  • Multimeter tester
  • Turn off the breaker to the dryer or unplug the dryer from the wall outlet. Take the front panel off the dryer. Remove the screws from above the dryer door. Lift the top from the dryer.

  • Remove the screws from the top, front corners inside the dryer cabinet. Lift the dryer front off the dryer and move it to the side of the dryer. Do not disconnect the door switch wires connecting the front panel to the dryer.

  • Find the two screws holding the interior frame beneath the dryer drum to the cabinet sides. Remove the screws and push the cabinet sides out and away from the drum. Pull the belt off the dryer drum. Lift the drum out of the dryer cabinet to expose the heating element.

  • Set the multimeter tester to Rx1k to check the continuity of the dryer heating element. Touch one lead from your tester to one end of the dryer heating element coil and the remaining lead to the other end of the element. Continuity registers between 8 and 12 ohms on the meter if the element is still good. No meter reading means the element is bad and needs replacing.
