Ceramic Fuse - 20 amp
★★★★★
★★★★★
(3)
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.
Micro Door Switch – Part Number: 3405-001034

Micro Door Switch
★★★★★
★★★★★
(12)
Part #3405-001034
This door switch, also known as a safety switch, is a genuine OEM replacement part for microwaves. It is a safety mechanism that sends signals to the microwaves control system, telling it when the door is open/closed. This ensures that the microwave only operates when the door is securely shut and switches off as soon as the door is open. Over time, this switch can become worn out or damaged. A faulty door switch can result in failure to switch the microwave on/off, lack of heat, and running with the door open. To confirm that the door switch is faulty, use a multimeter to test for electrical failure. To remove the faulty switch, disconnect the wiring connectors and take note of where they are positioned. Place the new switch in position and reattach the wiring connectors to the appropriate terminals and close the microwave door to check that the switch engages appropriately.

Part #WPR9800486
In your microwave, the diode allows current to flow one-way only, converting alternating current to direct current. If you notice that your microwave does not heat properly, you may need to replace the diode. This product is approximately 3 inches in length. Before completing this repair, be sure to disconnect the power source from the microwave. The diode is located inside the main compartment of the microwave, so you will need to open it up before you can complete this repair. This is an OEM part sourced directly from the manufacturer. Many of our customers have rated this repair as easy.

High-Voltage Diode
★★★★★
★★★★★
(4)
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 worked intermittently depending on how door was closed

  • Robert from Bainbridge Island, WA
  • A Bit Difficult

Remove top grille (2 screws), undo control panel (1 screw). Tilt down control panel, switches are on the left. There are actually three switches that are involved with the door, two horizontally mounted, one vertically mounted. This would be an EASY REPAIR, but it took me a while to figure out which of the three switches was bad, and a lso took a while to figure out that there is a plastic rod that inserts through the hole in the switch body. Once i figured this out went like a breeze. Lower horizontal switch was the bad one, but since the kit came with two switches i went ahead and replaced the upper horizontal one as well. IT appears that the horizontal switches are probably more likely to fail than the vertical switch based on the position of the switch and force angles. Works great now!

no heat

I looked up the #1 reason for no heat for my microwave on the site , and using my model number found that 92% of the time it was the Black Sleeve Diode. Ordered the $15 part, and installed it within 30 minutes. Most of the time was used for removing the built in microwave and removing the cover. Replaced the diode by finding it on the diagram that I printed from this site (free). Very relieved that we don't need to have our custom cabinetry re-sized to accommodate a new microwave. Thank you!

microwave oven blew fuse

  • tad from tamarack, MN
  • Really Easy
  • Less than 15 mins

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
