This is a plastic fan blade that attaches to the ventilation motor inside the microwave. It circulates air to cool internal components and, in over-the-range models, helps vent steam and cooking odors. Replace this blade if it is cracked, broken, or wobbling, which can cause excessive noise or reduced ventilation performance.

This thermistor measures temperature changes inside your microwave to control cooking functions and safety systems. It sends temperature readings to the control board to adjust power levels and cooking times. Replace this part if your microwave doesn't heat properly, overheats, or sensor cooking features don't work correctly.

Secures interior panels and components. Replace when stripped, corroded, or missing to stop rattles and secure loose trim. Verify fit with your model number.

This replacement power cord supplies electricity to the appliance so it can run safely and reliably. It replaces a worn, frayed or damaged cord to restore steady power and reduce risk of electrical problems. What it does:

• Delivers mains power from the outlet to the appliance's internal wiring
• Replaces cords with visible damage, exposed wires, or broken plug ends
• Stops intermittent power or complete loss of power caused by a damaged cord
• Helps prevent arcing and poor connections when original cord has failed

• Always disconnect power at the wall or breaker before inspecting or replacing the cord
• Secure the cord strain relief and ensure wire connections are tight and correctly routed

Microwave mounting hardware kit.

Lower cabinet base for microwaves. Provides structural support and stabilizes the unit. Replace if cracked, damaged, or warped to restore level positioning.

This main damper assembly regulates airflow between compartments to help maintain proper refrigerator temperatures. It replaces a worn or stuck damper to restore controlled air delivery for more consistent cooling performance. What it does:

• Controls the amount of cold air flowing from the freezer into the fresh-food compartment
• Helps stabilize internal temperatures when opening/closing doors or during mode changes
• Commonly fails by sticking open or closed, causing warm fresh-food temps or overcooling
• Works with the refrigerator's control system to modulate airflow based on demand

• Disconnect power before beginning any service to avoid electrical shock
• Handle the damper flap and cable/gear gently to prevent damage during installation
• Inspect surrounding seals and mounting points; secure all fasteners and reconnect any harnesses
• After installation, restore power and verify proper operation across temperature settings

Outer cabinet wrapper panel for microwave ovens. Encloses internal components and provides structural support. Replace if cracked, dented, or damaged.

• Helps stop vibration-related noise from loose assemblies
• Replaces missing or corroded screws that prevent proper closures
• Restores secure mounting after repairs or disassembly

• Use the correct screwdriver or bit to avoid stripping the head
• Tighten until snug—do not over-torque to prevent thread damage
