  If your Maytag Microwave Oven isn't working and the fuse has blown, the issue might stem from several causes. Begin by inspecting for open or loose wire harnesses. Additionally, examine the primary latch switch, monitor switch, high voltage capacitor, and high voltage transformer for any defects. Make sure to check the adjustment of the primary, interlock monitor, and door sensing switches and check the power relay.

  Edward WallaceAug 1, 2025
  If your Maytag Microwave Oven is cooking slowly, it could be due to a few reasons. First, check for fluctuations in your home's voltage. Also, check for loose connections in the high voltage circuit, specifically the magnetron filament circuit. Finally, the magnetron itself might be aging and need to be checked or replaced.

  If your Maytag Microwave Oven isn't responding to key inputs on the touch pad, here's what you can check. Ensure the key input is in the correct sequence as per the operation instructions. Inspect for any open or loose connections between the keypad and the PCB assembly. Also, look for shorted or open keypads, or a defective PCB assembly. Check the connection between the keypad and PCB assembly, replace the keypad membrane, or replace the PCB assembly.

  If your Maytag Microwave Oven isn't working, there's no display, and the fuse is okay, it could be due to an open or loose wire harness, an open thermal (magnetron) cutout, an open low voltage transformer, or a defective PCB assembly. If the thermal (magnetron) cutout is defective, check the fan motor. If the low voltage transformer is defective, check the PCB assembly.
