Jenn-Air Microwave Parts

Microwave not heating but all other functions work? This magnetron thermostat protects against overheating. Easy DIY repair in under an hour.

This 15 amp, 250 volt replacement fuse protects your appliance's electrical circuits by interrupting power when a fault or overload occurs. It restores safe operation once the underlying issue is fixed and the fuse is replaced. What it does:

• Acts as an overcurrent protection device for circuits rated up to 15 A and 250 V
• Prevents damage to wiring and components by opening the circuit during an overload or short
• Common symptom: appliance has no power or specific functions stop working after a sudden failure
• Replacing a blown fuse can resolve intermittent power loss or complete power failure tied to a single blown element

• Disconnect power to the appliance before inspecting or replacing the fuse
• Replace only with a fuse of the same amperage and voltage rating to maintain safety and proper protection
• Use insulated tools and avoid touching live terminals; internal access may require disassembly, follow OEM service instructions
• If fuses blow repeatedly, stop using the appliance.

Microwave won't heat? A faulty capacitor often causes no heating or weak performance. This high-voltage capacitor restores full power. Moderate DIY.

If your microwave runs but won't heat, a failed magnetron capacitor may be the cause. This high-voltage component stores energy for the magnetron.

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.

This humidity sensor detects moisture levels inside the microwave cavity during cooking. It allows the microwave to automatically adjust cooking time and power when using sensor-cook or auto-reheat functions. Replace this sensor if your microwave consistently overcooks or undercooks food on sensor settings, or if you receive error codes related to the humidity sensor.

Microwave light reflector directs bulb illumination inside cooking cavity. Replace if cracked, discolored, or missing to restore proper lighting. Confirm 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 not heating food? The high voltage transformer powers the magnetron. Common when you smell electrical burning or unit stops working.

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