Parts for Maytag MMV4205AAB: 03 - Cavity Parts

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.

This is a Whirlpool microwave magnetron. The microwave magnetron is one of the main components that control the heating function in the appliance. If a microwave has suddenly stopped heating but is still turning on normally, the problem could be the magnetron. Use a voltage tester to confirm whether this part is causing the problem. This component is made for installation in a microwave and oven combo where the microwave doubles as a vent hood. To replace this part, begin by unplugging the appliance and removing it from above the oven. Two people will be needed for this repair. This part requires exposure to highly sensitive electrical parts that could cause severe injury.This is a genuine OEM replacement part sourced directly from the manufacturer. This part is compatible with Whirlpool, Magic Chef, Amana, and Maytag appliances.

This replacement capacitor restores stable electrical timing and motor/run performance in compatible Whirlpool appliances. It helps the appliance start and run smoothly when the original capacitor has failed or weakened. What it does:

• Provides the stored charge needed for motor start/run circuits and control timing.
• Helps prevent motor hum, slow starts, or failure to start when the capacitor is failing.
• Reduces erratic cycling or intermittent operation caused by a weak capacitor.
• Supports reliable operation of blower, fan or small motor circuits that rely on a dedicated capacitor.

• Disconnect power to the appliance at the source before accessing electrical components.
• Capacitors can hold charge—discharge safely before touching terminals.
• Use insulated tools and avoid shorting terminals; verify correct fit and secure connections.

This stirrer cover rivet secures the microwave's stirrer cover in the ceiling of the oven cavity. A snug, intact cover helps protect the stirrer mechanism from splatters and keeps it properly positioned for consistent heating.

• Holds the stirrer cover firmly in place inside the cavity
• Helps prevent rattling noises from a loose or missing cover
• Can address issues like a sagging or fallen stirrer cover
• Replacing damaged or missing rivets supports even cooking performance

• Disconnect power to the microwave before servicing
• Access the interior cavity; support the cover while installing the rivet
• Insert through the cover and mounting hole; seat fully so the cover is secure
• Microwaves contain high-voltage components.

Color: brown. Measures about 9 inches in diameter.
