Microwave Parts

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

Suppresses electrical interference on your microwave's power line. Replace if cracked, damaged, or missing to reduce hum and radio-frequency noise.

This heater sheath is the metal protective tube that surrounds and secures a dryer's heating element, helping protect the element from abrasion and keeping heating airflow directed for reliable drying performance. What it does:

• Protects the heating element from contact and physical damage during operation
• Helps maintain proper airflow around the element for consistent heat distribution
• Reduces risk of element grounding or shorting caused by contact with other parts
• Can address symptoms like sputtering or uneven heating, burning/metallic smells, or visible damage to the element area

• 1 heater sheath

• Power off and unplug the appliance before service to avoid shock or injury
• Inspect the heating element and mounting hardware while replacing the sheath; replace any damaged parts
• Handle the sheath and element carefully—sharp edges may be present; wear gloves and eye protection

Microwave not heating? A failed diode rectifier prevents proper power flow to the magnetron. This one-way current component is essential for heating function.

Microwave won't heat but runs normally? This thermal fuse protects against overheating by cutting power when temperatures spike. Simple DIY fix.

Replacement lever for microwave door or latch mechanisms. Installs to operate control arms and moving parts. Needed when original is cracked, broken, or worn.

Microwave not heating? This magnetron generates microwaves to heat food. Replacing a faulty magnetron restores heating and stops cooking failures.

Molded wire clip that secures wiring and harnesses to the microwave cabinet. Replace if broken, cracked, or missing to prevent wire rubbing and chafing.

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.

Microwave won't power up or shuts off after seconds? Failed thermostats cause intermittent operation. Test for continuity—straightforward repair.

Glass cover that sits over your microwave's cooktop surface. Replaces cracked, chipped, or broken covers to restore a smooth, protective finish.

Replaces a damaged or oxidized noise filter assembly in your microwave. Includes fuse holders and mounting hardware. Order a new one if terminals are discolored.

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

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

Direct replacement noise filter assembly for microwaves. Reduces electrical interference. Replace if cracked, damaged, or missing to restore clean power.
