Ceramic Fuse - 20 amp

Part #WPM0805101
This microwave fuse is just over an inch in length. It has a white ceramic center, and metal on either end. This is a twenty amp 250-volt fuse, and is used to power your microwave. If your microwave will not heat properly, will not turn on, or the touch pad becomes unresponsive, there could be a faulty fuse which should be replaced. Remember, since this part contains an electrical charge, before you replace the fuse from your microwave, make sure that the power is disconnected from the unit. This part is sold individually. NOTE: Make sure your microwave is unplugged, and your capacitor is discharged before you begin this repair. A capacitor stores large amounts of electricity even after your microwave is unplugged.

High-Voltage Diode

Part #DE91-70063D
This high-voltage diode is designed for use within various makes and models of microwaves and is a genuine OEM part that converts alternating current (AC) into direct current (DC). If you notice your microwave turns on and starts but does not heat anything, this diode is likely responsible. You can check the continuity of the diode with a multimeter before outright replacing it, but it is important to remember that doing any repairs on a microwave and dealing with sensitive electrical components should be done carefully and with the appropriate precautions to avoid any hazards. To replace the high-voltage diode in your microwave, disconnect it from power and allow it to discharge. Using the appropriate screwdrivers, gain access to the control panel of the microwave. Using an insulated screwdriver, release any electrical charge in the capacitor by touching it across the terminals. Then you can remove any hardware securing the diode, including the harness connecting it to the capacitor, which may be easiest done with pliers. Connect the new diode to the capacitor terminal and the securing bracket, and then reassemble your microwave before connecting it to power again.

microwave oven blew fuse
27 of 43 people found this instruction helpful.
  • tad from tamarack, MN
  • Really Easy
  • Less than 15 mins
  • Pliers, Screw drivers
First I removed upper front grill by removing two Philips head screws on top and pulling off. This exposed the Philips head screw which holds control panel in place. After removing screw I pushed up on panel and it came off to expose fuse. With needle nose pliers I removed old fuse and again with pliers held new fuse in position. With th e help of a bladed screwdriver, I pushed new fuse into holder, then replaced panel, screw and grill. This took less than 15 minutes even as one of the wires on control panel pulled out of connection and took some time to locate where to reconnect, otherwise was an easy fix

Removed control panel, discharged HV capacitor. Removed old diode, tested to confirm failure. Replaced part. Other than the removal of the panel swapping the part was almost as easy as replacing a light bulb.
