Parts for Frigidaire FGMC3066UDA: Microwave Parts

This thermostat is a temperature-sensing switch that helps your appliance maintain the set temperature by opening and closing the circuit as conditions change. Replacing a weak or failed thermostat restores consistent cycling and stable performance. What it does:

• Monitors temperature and opens/closes its electrical contacts to control the circuit
• Helps the unit cycle on and off to maintain an even, target temperature
• A failed thermostat may cause temperature swings, short/long cycling, constant running, or no cycling at all

• 1 thermostat

• Disconnect power (and gas, if applicable) before servicing
• Access the thermostat location per your model; note wire positions and transfer any brackets/insulators from the original
• Make secure wire connections and route leads away from sharp, hot, or moving parts
• Reassemble covers, restore power, and verify proper cycling and temperature regulation

Retainer bracket for microwaves. Secures internal components in place. Replace if broken, cracked, or missing to restore proper fit and stability.

This is an adjustable leveling foot that attaches to the bottom of the microwave to keep it stable and level on the countertop. It threads into the base of the unit and can be turned to adjust the height. Replace this foot if it is cracked, missing, or stripped, which can cause the microwave to wobble or sit unevenly.

Microwave not heating? This diode directs current flow to the magnetron and protects control circuits. Quick install restores heating when failed.

Range hood fan won't start or runs slowly? This capacitor stores energy to start the motor. Common DIY repair that restores proper ventilation.

This is a cooling fan motor used in a microwave oven to circulate air and prevent internal components such as the magnetron and electronics from overheating. It typically runs during cooking and may continue running briefly after the microwave shuts off. Replace this motor if the microwave is overheating, shutting off unexpectedly, or if the fan is noisy, runs sluggishly, or doesn't spin at all.

Protective trim cover that shields and finishes exposed components on your microwave. Replace if cracked, broken, or missing to restore protection.

Illuminates the interior of your microwave or cooking surface below. Replace when bulb burns out or flickers. Verify compatibility with your model.

Glass turntable tray rotates food for even heating in your microwave. Replace this tray if yours is cracked, chipped, broken, or missing to restore function.

Fix a microwave that won't heat food or makes loud humming noises. This magnetron generates the microwave energy needed to cook. Moderate DIY repair.

Secures components within your microwave to keep them aligned and stable. Replace if cracked, broken, or missing to restore support and prevent rattling.

A push-button door switch that tells the appliance when the door is open or closed so lights, fans, or controls respond correctly. Replaces a worn or broken door-actuated switch to restore normal operation and interior lighting. What it does:

• Detects door open/closed position to control interior lights or related circuits
• Stops lights from staying on when the door is closed, preventing unnecessary power use
• Restores proper cycling of door-dependent functions and controls
• Commonly used when lights fail to turn on/off or when door-operated features are intermittent

• One replacement push-button door switch

• Disconnect power before servicing to avoid shock or damage
• Access typically requires removing interior trim or the light housing—keep fasteners for reassembly
• Verify switch orientation and terminal connections match the original before connecting

Microwave tripping breaker or won't start? A faulty door switch is often the cause. This safety switch detects door position. Moderate DIY repair.

This replacement lever is the small actuator that engages control linkages so doors, latches or dispenser mechanisms move and stay in position. Replacing a worn or broken lever restores reliable mechanical operation and alignment. What it does:

• Transfers motion from a handle or control cam to the linked mechanism
• Helps door/latch/dispenser engage and stay in the correct position
• A damaged or cracked lever can cause sticking, poor latching, or intermittent operation
• Commonly fails from wear, impact, or plastic fatigue

• Disconnect power to the appliance before beginning work to avoid injury
• Removal typically requires basic hand tools; keep fasteners for reuse
• Handle small plastic parts carefully to avoid damage during installation
• Test the mechanism through a full cycle after installation to ensure proper engagement

This is a small microswitch used in the microwave's door interlock system or control mechanism. It detects whether the door is properly closed and signals the unit to allow or prevent operation for safety. Replace this switch if the microwave does not start when the door is closed, runs with the door open, blows a fuse repeatedly, or fails to respond when buttons are pressed.

Fixes microwave with no power or intermittent operation caused by burnt connectors or damaged wiring. Restores electrical connections between components.

This is an electrical noise filter designed to suppress electromagnetic interference generated by the microwave's internal components. It connects inline with the power supply to prevent electrical noise from affecting the microwave's operation or other nearby electronics. Replace this filter if your microwave displays erratic behavior, produces unusual buzzing sounds, or interferes with other appliances on the same circuit.

Microwave won't start or is completely dead? This fuse protects against electrical overload. Requires disassembly to access. Often replace with switches.
