Parts for Kitchenaid KCMS1555SSS0: 05 - Oven Interior Parts

High-voltage capacitor for microwave ovens that stores and releases the electrical charge needed to drive the magnetron, restoring heating when the original capacitor has failed and preventing further electrical stress. What it does:

• Stores high-voltage electrical energy used by the magnetron to produce microwave energy.
• Works with the high-voltage transformer and diode; a failed capacitor can cause no-heat or reduced-heat conditions.
• Common, widely accepted symptoms: microwave not heating, loud humming, arcing/sparking, or blown fuse.
• Replacing a defective capacitor can stop repetitive electrical faults and protect other high-voltage components.

• Always unplug the appliance before beginning service and discharge the capacitor with an appropriate resistor or discharge tool.
• Handle and test the component using insulated tools; capacitors can retain dangerous charge even when unplugged.
• Verify correct part orientation and secure connections; use only the exact replacement specified by the manufacturer.

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 electrical safety fuse opens the circuit when a short or overcurrent occurs. Replacing a blown fuse can help restore power after the root cause is corrected, protecting controls and wiring from further damage.

• Protects the appliance by interrupting power during overcurrent or short-circuit events
• When open/blown, the appliance may be completely unresponsive
• Helps prevent damage to control boards and wiring during faults
• Often fails after a component shorts or a power surge occurs

• Disconnect power to the appliance before servicing
• Use a multimeter to test the fuse for continuity; replace only if open
• Install a fuse with the exact same rating and form factor as the original
• If the new fuse blows again, stop and diagnose the underlying fault; consider service for high-voltage systems
