How to Repair a Frigidaire Dryer Fuse

If your dryer won't heat, a tripped thermal fuse may be the culprit. A thermal fuse is a safety feature that is found in modern dryers to prevent dangerous overheating that could result in a fire. It is not possible to repair a thermal fuse. Once a dryer has reached its temperature threshold and the fuse has tripped, it must be replaced.

Things You'll Need

  • Putty knife
  • Screwdriver
  • Needle-nosed pliers
  • New thermal fuse

Instructions

    • 1

      Confirm that your home's circuit breaker has not been tripped. If one side of the breaker has been thrown the dryer could still tumble but not heat.

    • 2

      Unplug your dryer to eliminate the risk of electrical shock.

    • 3

      Open your dryer's cabinet top. Release the spring catches under the top by pushing a putty knife into the front of the dryer on each side. Swing the cabinet top out of the way.

    • 4

      Remove the screws that hold the bottom of the front panel, if necessary. Some models have two screws while others have four. Disconnect the door switch and any other wiring. Make note of how the wiring should be reconnected.

    • 5

      Locate the thermal fuse. On most newer Frigidaire dryer models the thermal fuse is tucked towards the back of the dryer above the rear drum bearing. If the thermal fuse is "open" then it is faulty and should be discarded. Order a replacement thermal fuse for your model of Frigidaire dryer.

    • 6

      Remove the blown thermal fuse. Remove the wires leading to the thermal fuse by pulling on the metal slip-on connectors with a pair of needle-nosed pliers. Do not pull on the wires themselves.

    • 7

      Replace the thermal fuse with a new one by reattaching the metal slip-on connectors.

    • 8

      Reassemble your dryer by reversing steps taken to disassemble it. Plug your dryer into a power outlet.

    • 9

      Run your dryer through a cycle to determine if it is functioning properly.

    • 10

      Determine what caused your dryer to overheat. Poor airflow is the number one cause for a thermal fuse to trip. The usual suspect is a poorly functioning or clogged dryer vent.

Tips & Warnings

  • If the thermal fuse is found open, it often is a good idea to replace the safety thermostat at the same time, since the thermostat has likely been working overtime. Some manufacturers supply both a fuse and a thermostat in a single kit.
  • Never attempt to bypass a thermal fuse. It is a safety feature of your dryer that is designed to prevent overheating.
  • Attempting to repair your dryer may void any warranty on your machine. If your dryer is still under warranty, contact Frigidaire to arrange a service call.
