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.

CAPACITOR-

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.

There are actually three switches that are involved with the door, two horizontally mounted, one vertically mounted.
