Comes with two grease filters in a pack. Color: metallic. Each filter measures about 5 inches wide by 8 inches deep.

This ventilation motor drives the vent fan to remove smoke, steam and cooking odors from the range hood assembly. It restores proper airflow so the ventilation system can clear air more effectively during use. What it does

• Replaces a worn or failed vent fan motor so the hood or microwave exhaust regains suction.
• Helps stop symptoms like no airflow, weak exhaust, or unusual motor noise during vent operation.
• Works with the fan/blower assembly to move air through the vent duct and filters.
• Matches OEM function and mounting so it integrates with the existing blower housing.

• One motor-ventilation (single motor unit)

• Install only with the appliance unplugged or power turned off at the breaker.
• Handle the motor and wiring harness carefully; reconnect all plugs and fasteners exactly as removed.
• Verify fan spins freely after installation before reassembling covers or panels.

This temperature thermistor is the sensor that lets the control board monitor and regulate appliance temperature for reliable cooling performance. Replacing a failing thermistor can restore proper temperature control and cycling. What it does:

• Senses internal temperature and sends readings to the control board
• Helps the compressor, fans, and defrost system run at the right times
• Commonly linked to symptoms like incorrect temperatures, overcooling, or frequent on/off cycling
• A faulty thermistor can cause improper defrost timing or erratic cooling behavior

• Disconnect power before inspecting or replacing the sensor to avoid shock
• Handle the sensor and wiring connector gently to avoid damage
• Mount the sensor in the original location and secure wiring per OEM routing

The Thermostat is an OEM part for GE microwaves. This part regulates the temperature within the microwave, ensuring it operates within safe and efficient temperature ranges. It helps prevent overheating by monitoring and controlling the internal temperature, protecting both the appliance and the user.

Causes of a bad thermostat can include wear and tear over time, electrical malfunctions, or damage from power surges.

Symptoms of a bad thermostat include:

• Microwave not heating properly
• Overheating or shutting off unexpectedly
• Error codes related to temperature issues
• Inconsistent cooking times

This OEM GE part is also compatible with Hotpoint, RCA, and some Kenmore models.

This magnetron thermostat assembly helps prevent magnetron overheating by opening the circuit when temperatures get too high, protecting microwave components and helping restore normal operation once cooled. Fits the OEM thermostat function for safe thermal control. What it does:

• Senses excessive magnetron temperature and interrupts power to prevent overheating
• Helps stop microwave heating when the magnetron runs too hot or thermal limits are exceeded
• Common symptom: microwave powers on but does not heat or intermittently fails to heat
• Restores normal operation after cooling if no other faults are present

• Disconnect power and fully discharge the high-voltage capacitor before servicing
• Replace only with the correct OEM thermostat assembly to ensure proper fit and safety
• Handle with care; avoid shorting contacts or damaging terminal connections

The Diode Assembly is an OEM part for GE microwaves. It plays a crucial role in converting alternating current (AC) to direct current (DC), which is essential for the microwave’s high-voltage functions, including powering the magnetron to generate microwave energy.

Over time, diodes can fail due to electrical surges, excessive heat, or wear and tear. A faulty diode assembly can lead to inefficient or non-functional microwave operation, impacting its ability to heat food properly.

Symptoms of a bad diode assembly include:

• Microwave not heating food
• Sparking or arcing inside the microwave
• Burning smell or unusual noises during operation
• Microwave turning on but failing to generate heat

This GE replacement part is also compatible with Hotpoint, RCA, and some Kenmore models.

The Cooking Tray is an OEM part for GE microwaves. This tray sits on the turntable in the microwave and holds the food items being heated or cooked, allowing for even rotation and uniform cooking.

Causes of a bad cooking tray can include cracks or breaks from heavy use, exposure to extreme temperatures, or accidental drops.  

Symptoms of a bad cooking tray include:

• Cracks or chips on the tray
• Difficulty in rotating or the tray not rotating at all
• Unstable placement of food items
• Uneven cooking results

This OEM GE part is also compatible with Hotpoint, RCA, and some Kenmore models.

Shaft assembly that transfers rotational force from the motor to the appliance's rotating component, restoring smooth, aligned rotation and helping reduce noise and vibration caused by worn or damaged shaft parts. What it does:

• Transfers motor rotation to the appliance's rotating component (drum, basket or agitator depending on model)
• Restores proper alignment to reduce wobble and vibration during operation
• Helps stop grinding, scraping or loud knocking that can occur when a shaft is worn or damaged
• Works with existing bearings/bushings to maintain smooth rotation

• Always disconnect power at the breaker before removing panels or working on the appliance; if the appliance uses gas, shut off the gas supply as required.
• Follow the appliance service manual for disassembly order and correct shaft orientation during installation.
• Inspect related bearings, bushings, seals and fasteners; replace any worn components to prevent premature failure.

This rack holder supports the removable rack inside the appliance cavity, keeping it level and secure during use. Replace a cracked or missing holder to restore proper rack positioning and safer, more reliable operation.

• Provides a fixed support point for the rack inside the cavity
• Keeps the rack level and prevents tipping or slipping
• Helps the rack slide in and out correctly when supports are intact
• Common signs to replace: rack won't stay in place, tilts or falls, visible damage or missing holder

• Disconnect power and allow the appliance to cool completely before servicing
• Remove the rack to access the holder
• Remove the fastener(s), note orientation, and swap in the new holder
• Reinstall the rack and confirm it sits securely before use

The Fuse is an OEM part for GE microwaves. It serves as a safety device designed to protect the microwave from excessive current that can cause overheating and potential fire hazards. When the current flowing through the microwave circuit exceeds a certain level, the fuse blows or breaks, cutting off the power to prevent damage or fire.

Common causes for a fuse to blow include power surges, faulty wiring within the appliance, or the use of microwave inappropriate containers that cause sparks. It is essential to address these issues not only to replace the fuse but also to correct the underlying problems to prevent future failures.

Symptoms of a bad fuse include:

• The microwave suddenly stops working.
• No signs of power or response even when the microwave door is closed and the start button is pressed.

This GE replacement part is also compatible with Hotpoint, RCA, and some Kenmore models.

This capacitor helps the refrigerator compressor start and run more reliably by providing the motor with an extra electrical boost when needed. Replacing a failing capacitor restores proper starting torque and improves cooling consistency. What it does:

• Provides the extra electrical charge the compressor motor needs to start and maintain normal operation
• Reduces hard-starting or repeated starting attempts that can overheat the compressor
• Can stop or reduce humming, clicking, or nonstop running caused by a weak start circuit
• Supports stable compressor performance for consistent refrigerator temperatures

• One capacitor (single unit)

• Always disconnect power to the appliance before servicing electrical components
• Discharge the capacitor before touching terminals to avoid shock
• Inspect wiring and mounting; replace only with the exact OEM part number
