Includes one microwave vent filter. Color: metallic. Measures about 6 inches wide by 11-1/2 inches deep.

This grease filter is an OEM replacement for Whirlpool microwaves. The filter helps to maintain the cleanliness and efficiency of the appliance. It is located underneath the microwave, typically in a slot behind a protective grille. Its primary function is to trap grease particles and prevent them from accumulating on internal components, ensuring optimal airflow and reducing the risk of fire.

Causes of a bad grease filter include excessive use without proper cleaning, exposure to high temperatures or grease splatters, or reaching the end of its lifespan due to regular wear and tear.

Symptoms of a clogged or defective grease filter:

• Reduced airflow or suction from the range hood
• Persistent cooking odors lingering in the kitchen
• Visible buildup of grease or grime on the filter or surrounding areas
• Clogged or obstructed air vents or ductwork

This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore range hoods and over-the-range microwaves.

The Switch is an OEM part for Whirlpool microwaves. This switch is crucial for the proper operation of the microwave, as it ensures the correct function of the door mechanism and the control panel. 

Causes of a bad microwave switch can include wear and tear over time, damage due to frequent use, or electrical faults that prevent it from functioning correctly.

Symptoms of a bad microwave switch include:

• The microwave not starting or stopping unexpectedly
• The door not latching properly
• Error messages on the control panel
• The microwave light not turning on or off as expected

This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.

The Switch is an OEM part for Whirlpool microwaves. It controls the turning on and off of power to the microwave during cooking cycles as well as detects positions within cycles to signal appropriate actuations of the microwave's magnetron, fans, and lights. The switch is a crucial electrical component that facilitates the fully automatic operation of preset cooking programs.  

Causes of a bad switch can include wear and tear over time or unexpected surges that cause electrical component failure.

Symptoms of a bad switch include:

• Cooking programs failing to advance properly or stopping mid-cycle unexpectedly
• The microwave failing to turn on or experiencing power issues  
• Random noises, humming, or lights occurring when the microwave is supposed to be idle
• Buttons or controls acting intermittently unresponsive

This OEM Whirlpool part can also be used on Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore/Sears brand appliances. 

Replacement interlock spring that provides tension for the appliance door latch so the door closes and the interlock switch can engage for normal operation. Restores reliable door engagement and latch return in compatible Whirlpool appliances. What it does:

• Provides tension to the door latch/interlock assembly so the door stays securely closed during use.
• Ensures the latch returns to the closed position and allows the interlock switch to complete the appliance's safety circuit.
• Helps resolve symptoms such as a loose or non-returning latch, door that won't stay closed, or cycles that stop because the door won't engage.
• Works as a direct replacement for the listed interlock spring in compatible Whirlpool assemblies.

• Disconnect power to the appliance before servicing to avoid electric shock or injury.
• Basic hand tools are typically required; panels or the door may need partial disassembly—refer to the model's service guide.
• Inspect the latch, striker, and interlock switch for wear or damage and replace if needed; improper installation can prevent correct engagement.

This inverter converts the refrigerator's incoming power and controls compressor speed so the cooling system runs efficiently. Replacing a failed inverter restores proper compressor operation and helps return normal cooling performance. What it does

• Converts incoming AC power to the DC signals the variable-speed compressor needs
• Regulates compressor speed for temperature control and energy-efficient operation
• Works with the fridge's main control systems to manage compressor operation

• Disconnect power to the appliance before beginning any service to avoid shock
• Handle the board by its edges and avoid touching components; observe ESD precautions
• Mount and connect using original-style fasteners and harness connectors; verify secure, corrosion-free connections
• Check compressor, main control board, and harness for related issues if symptoms persist after replacement.

This is a thermal safety fuse that opens the circuit if temperatures rise beyond a safe limit, protecting the appliance from overheating and preventing further damage. Replacing a failed fuse restores power to the affected circuit once the underlying cause is addressed.

• Monitors temperature in a protected circuit and cuts power if unsafe heat is detected
• Helps prevent overheating-related damage
• Typical failure signs: no power/no operation, cycle won't start, shuts off mid-cycle after overheating event
• Must not be bypassed; replace if open and investigate the root cause of overheating

• Unplug appliance or disconnect power before service
• Verify the fuse is open with a multimeter; replace only after correcting any airflow/overheating issues
• Install in the same orientation and location as the original to ensure proper temperature sensing
• Handle wiring carefully; transfer connectors one at a time to avoid miswiring

The Screw is an OEM part for Whirlpool microwaves. It is responsible for securing various parts of the microwave together. This screw ensures a tight and secure fit for parts and helps maintain the structural integrity of the microwave, preventing any loose or rattling parts.
