Light Bulb - 40W
★★★★★
★★★★★
(78)
Part #8009
This an authentic OEM 40-Watt replacement light bulb, used in a number of household appliances. It is specially designed to withstand extreme temperatures, which is why these replacement bulbs are most often used to light the inside of refrigerators and ranges. It features a standard socket base, which means you simply unscrew the burnt-out bulb and screw in the replacement. Depending on the appliance you may require a screwdriver or nut driver to access the light bulb. We recommend you wear work gloves while handling this replacement part. It is constructed of glass and metal and is sold individually. Depending on the appliance and location of the bulb within it, you may want to consider disconnecting power and using a flashlight for easier access to unscrewing and re-screwing in your bulb during this repair.

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.

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.

This incandescent lamp in your microwave lights up the interior of the appliance and the cooktop if it is positioned above your stove. This allows you to easily keep an eye on your food while it cooks. It operates at 130 volts and has a power rating of 4 watts. If the bulb fails to light up or shows signs of damage like a broken filament or blackened appearance, it should be replaced. To remove the lamp, refer to your user manual for specific instructions. Generally, you will need a screwdriver to remove the cover or panel near the lamp and then unscrew the bulb counterclockwise to detach it from the socket. Take care when handling the lamp, using a cloth or tissue to avoid direct contact. It is important to confirm the number of lamps needed for your appliance before making a purchase since this OEM replacement part is sold individually.

Part #WP59001168
The high-voltage capacitor is an electronic device that holds a charge of electricity in the high-voltage circuit of the microwave. The capacitor stores electricity similar to how a battery does, but can be charged and discharged instantly. If your microwave will not produce heat, there could be an issue with the capacitor. This genuine OEM replacement high-voltage capacitor is approximately 5 inches long x 2 inches wide, and is compatible with most microwave brands. NOTE: Make sure your microwave is unplugged, and that your capacitor is discharged before you begin this repair. A capacitor stores large amounts of electricity even after your microwave is unplugged.

microwave oven blew fuse

  • 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.
