Parts for Kenmore 721.80802401 (72180802401, 721 80802401): Interior Parts 1 Parts

Fastens panels, brackets, and covers inside the microwave cabinet. Replace if cracked, broken, or missing to restore secure mounting and alignment.

Turntable stopped rotating or making grinding noise? This synchronous motor restores smooth tray rotation for even heating. Simple DIY fix with a screwdriver.

Microwave not heating or sparking inside? This high voltage capacitor stores power for the magnetron. Common repair taking 30-45 minutes with care.

Microwave won't heat but runs normally? A failed magnetron is the likely cause. This part generates the microwaves that cook food. Moderate DIY repair.

Fix loud noise, humming, or overheating in your microwave. This cooling fan motor restores proper airflow. Moderate difficulty repair with basic tools.

Microwave won't heat or makes loud buzzing noise? The diode regulates magnetron current flow. Simple repair—test with multimeter for continuity.

This thermostat controls oven/dryer temperature by opening or closing its contacts as the appliance reaches set temperatures, helping maintain safe and consistent operation. Replaces a worn or failed thermostat to restore proper temperature regulation. What it does:

• Senses temperature and interrupts heating when limits are reached to prevent overheating
• Re-establishes heating when temperature falls, maintaining normal cycle performance
• Commonly installed when an appliance won't heat, overheats, or cycles erratically
• Works as a direct replacement for the OEM thermostat designed for compatible LG units

• One thermostat

• Disconnect power to the appliance before starting any repair to avoid shock or injury
• Note wire locations or take a photo before removing wiring; reconnect wires to the same terminals
• Use a multimeter to verify thermostat continuity and correct operation before and after replacement

This fan assembly replaces a worn or failed fan to restore proper airflow and cooling performance. It installs in the appliance to move air across components for efficient operation and temperature control. What it does:

• Contains the fan motor and blade to circulate air through the appliance
• Restores airflow when existing fan is noisy, slow, or not spinning
• Helps reduce overheating by directing air over coils or components
• Stops symptoms such as unusual fan noise, warm compartments, or cooling loss

• One fan assembly (motor and blade) as shown

• Disconnect power before starting any repair to avoid shock or injury
• Handle the blade and motor carefully to avoid bending or damaging the fan
• Verify mounting location and connector orientation before securing the assembly

This is a motor start/run capacitor that helps the appliance's motor start and run smoothly by supplying a brief boost of electrical energy. Replacing a failing capacitor restores reliable motor startup and operation. What it does:

• Provides the brief electrical surge needed to start and keep the motor running
• Commonly linked to motors that hum, fail to start, or run intermittently
• Helps prevent overheating from repeated start attempts when functioning properly
• Works with the appliance's start circuitry to ensure consistent performance

• Disconnect power to the appliance before accessing electrical components
• Discharge the capacitor and use insulated tools
• Observe polarity/terminal layout and secure connections to factory specifications
• Dispose of the old capacitor according to local electronic-waste regulations
