The Diode is an OEM part for Whirlpool microwaves. It plays a crucial role in the microwave's operation by allowing electrical current to flow in one direction, essential for converting AC power to DC power, which is necessary for the microwave's components to function correctly.
Over time, the diode can fail due to electrical surges, general wear and tear, or exposure to high heat. A bad diode can disrupt the microwave's ability to heat food properly, leading to inefficient performance or complete appliance failure.
Symptoms of a bad diode include:
- Microwave not heating
- Sparking or unusual noises during operation
- Burning smell from the microwave
- Microwave shutting down shortly after starting
This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.
