Parts for Kenmore 911.9871190 (9119871190, 911 9871190): Microwave Module Section Parts

This metal rack support holds the cooking rack in place inside your microwave. It maintains proper spacing between the rack and microwave walls for even heating. Replace it if your microwave rack wobbles, falls, or doesn't stay level during cooking.

Hook spacer for electric ranges, ovens, and microwaves. Replaces worn, cracked, or missing spacers. Maintains proper spacing and alignment.

This microwave high-voltage capacitor stores and releases energy in the high-voltage circuit to power the magnetron. Replacing a failed capacitor helps restore proper heating and protects other components in the high-voltage system.

• Works with the transformer and high-voltage diode to supply the magnetron with the required voltage
• Failure may result in the unit running but not heating
• Shorted capacitors can blow the internal fuse or trip a breaker; opens may cause loud humming or buzzing
• Visible swelling or leakage on the capacitor body are common failure signs

• Unplug the microwave; capacitors can retain a dangerous charge even when unplugged—discharge using an appropriate, insulated method before servicing
• Note wire positions and terminal orientation; transfer any mounting hardware from the original part
• Mount securely and route wires to avoid pinching

Microwave not heating or heating unevenly? A failed magnetron is the likely cause. This high-voltage tube generates microwave energy to cook food.

Microwave not heating or humming loudly? The high-voltage diode converts AC to DC for the magnetron. Repair takes 30-45 minutes with basic tools.

This high-voltage transformer steps up household current to power your microwave's magnetron tube. It converts standard household voltage to the high voltage needed to generate microwaves for cooking. Replace this transformer if your microwave doesn't heat food, makes loud humming noises, or repeatedly blows fuses.
