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

Replacement door tension spring for microwaves. Restores door balance and secure closure when original spring is worn, broken, or missing.

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 is a fixed high limit thermostat that monitors the internal temperature of the microwave and shuts off the unit if it overheats. It acts as a safety device to prevent damage to components and reduce fire risk. Replace this thermostat if the microwave shuts off unexpectedly during use, fails to start, or if continuity testing shows the thermostat is open.

This interlock is the door latch assembly that keeps a dryer door closed and prevents the dryer from running when the door is open. It restores proper door sensing for safe, reliable operation. What it does:

• Secures the dryer door so the machine only runs with the door fully closed
• Activates the door-safety circuit so the dryer stops when the door opens
• Commonly replaced when the door won't latch or the dryer won't start
• Helps eliminate intermittent start/no-start symptoms related to door sensing

• One interlock assembly

• Disconnect power before starting any repair to avoid electrical shock
• Replace only with the exact part number specified for your model
• Basic hand tools are typically required; avoid forcing plastic clips and connectors

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.

Fix microwave overheating or won't heat issues with this thermostat temperature limiter. Regulates oven temperature and prevents overheating damage.

Microwave not heating food? The magnetron generates microwaves for cooking. Moderately difficult repair requiring high-voltage precautions.

Fix uneven cooking or incorrect oven temperatures with this temperature sensor. Detects cavity temperature for accurate bake cycles. Easy DIY repair.

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.

Replacement mounting screw for microwaves. Secures panels, brackets, and interior trim to the frame. Needed when original screws are stripped or missing.

This is a replacement screw used to secure appliance parts and panels. It restores proper fastening where the original screw is missing, stripped, or corroded. What it does:

• Secures panels, brackets, or components in place to maintain appliance alignment
• Replaces lost, damaged, or rusted fasteners for a reliable hold
• Helps prevent rattling or movement caused by a missing screw
• Works wherever the OEM screw specification and fit match

• One screw

• Use the matching screwdriver or driver bit; avoid overtightening to prevent stripping
• Disconnect power and follow appliance safety precautions before servicing
