If your Whirlpool or Maytag oven has gone on strike and will not heat, it could be the thermal fuse has gone bad. However, be aware that there is probably another underlying reason causing the fuse to fail, so you will need to do further testing on the elements, and/or the control board relay to find the initial problem. To check and replace the thermal fuse, you will need a Phillip’s head screwdriver, needle-nose pliers, and a volt tester.
Perform a Diagnostic Test on the Thermal Fuse
- Unplug your oven before starting any work on it.
- Access the back of the oven and remove the bottom middle panel by removing the two screws, sliding the panel down and pulling out. Be careful, the panel may have sharp edges.
- Then, follow-up be removing the top panel, which has several screws securing it. When removing the last screw be sure to hold the panel so it doesn’t fall. Caution, it, too, can have sharp edges.
- Gently remove the terminals with your pliers. Get out your volt tester and set to sound. If the fuse is good you will hear a high-pitched tone. If not, you’ll hear nothing.
Replacing the Fuse
- While removing the screw and holding the fuse in place, also note the position of the fuse.
- Install the new fuse in the same position as the inoperable one you just removed.
- Reinstall the wire terminals.
- Reinstall the upper panel by holding the panel in place while replacing the two top screws. Then finish replacing all of the other screws.
- Replace the middle lower plate, placing the tabs on the plate into the notches on the back of the oven. Push up and reinstall the screws.
Remember that while you have replaced the thermal fuse, that initial problem may still remain and burn out another fuse. Be sure to run diagnostics on other potential problems to find the initial source. Then repair or replace as necessary.
