Parts for HMV1472B3HS: Oven Cavity Part Parts

Protects the microwave's waveguide opening from food splatter and grease. Replace when discolored, burned, or damaged to prevent arcing. Verify fit.

Microwave not heating or heating slowly? This magnetron produces the microwaves that cook food. Restores full heating power to your microwave.

Microwave not heating? The high voltage diode converts power for the magnetron. DIY-friendly repair with proper safety precautions. Discharge capacitor first.

This humidity sensor measures humidity levels inside the fresh-food compartment so the refrigerator can regulate humidity-sensitive features and help preserve produce. It replaces a failed or inconsistent humidity reading for better climate control. What it does

• Detects moisture/humidity in the fresh-food area so the fridge control can adjust dampers or humidity settings
• Helps reduce excess moisture, condensation, or premature spoilage when functioning properly
• Can resolve symptoms like erratic humidity readings, dampness or frost buildup, or related control errors
• Interfaces with the refrigerator control board to provide real-time humidity feedback

• One humidity sensor module

• Disconnect power to the appliance before replacing the sensor to avoid shock or damage
• Typically plugs into the control harness; handle the sensor and connector with care to avoid bending pins
• Avoid contaminating the sensor element with liquids or cleaners during installation
• Check the control board and wiring harness for faults

A defrost thermostat that senses evaporator temperature to properly stop the defrost heater when the temperature rises. Replaces a failed defrost thermostat to help prevent over-heating of the heater and ensure proper defrost cycles. What it does:

• Opens/closes at approximately 160°F / 95°F to terminate defrost cycles
• Stops the defrost heater once the evaporator has warmed, preventing damage
• Helps restore proper cooling when a failed thermostat causes extended or no defrost
• Compatible with common refrigerator defrost systems that use a temperature-sensing thermostat

• Turn off power to the appliance before servicing to avoid electric shock
• Typically mounts near the evaporator; handle the sensor bulb and capillary tube carefully
• Confirm fit and orientation against the original part before final assembly

Microwave tripping breaker or won't heat? This thermal cutoff thermostat monitors temperature to prevent overheating. Straightforward replacement.

Microwave tripping the breaker or won't power on? This thermostat protects against overheating. Common fix when the unit is dead. Moderate DIY repair.

This is a plastic latch board or support bracket that holds the door latch switches in the correct position inside the microwave. It ensures the door interlock switches align properly when the door is closed. Replace this part if the microwave does not start, runs with the door open, or the door latch mechanism feels loose or misaligned.

This is a white plastic lever that actuates the door interlock switch when the microwave door is opened or closed. It transfers the mechanical motion of the door latch to the safety switch, which prevents the microwave from operating with the door open. Replace this lever if the microwave won't start, runs with the door open, or if the lever is cracked or broken.

The Micro Switch is an OEM part for GE microwaves. This part ensures the appliance operates only when the door is securely closed. It controls the electrical circuit, allowing the microwave to start heating food when the door latch engages the switch.

Causes of a bad micro switch can include wear and tear from frequent use, electrical issues, or physical damage from slamming the microwave door.  

Symptoms of a bad micro switch include:

• The microwave not starting or stopping unexpectedly
• The microwave running even with the door open
• Intermittent power issues
• The door not latching or the microwave indicating the door is open

This OEM GE part is also compatible with Hotpoint, RCA, and some Kenmore models.

Grease filter for range hoods and over-the-range microwaves. Dimensions: 5-1/16" x 7-5/8" x 3/32" (5.0625 x 7.625 x 0.09375). Rectangle shape. Captures grease from cooking air. Replace when clogged, discolored, or every 6-12 months.

Absorbs odors and filters grease from microwave exhaust. Replace when air quality diminishes or every 6 months. Verify fit with your model number.

If your microwave turntable won't spin or makes grinding noises, the turntable motor likely failed. Simple fix with basic screwdriver work.

Turntable stopped rotating? This microwave turntable coupler connects the motor to the glass tray. Simple pull-up removal makes this a quick DIY fix.

Turntable won't rotate in your microwave? The rotating ring assembly supports smooth turntable spinning. Simple DIY fix in under 15 minutes.

Replace a cracked, broken, or missing wind guide cover in your microwave. Directs airflow and shields internal components from debris buildup.

Secures the air damper assembly in your microwave, keeping it aligned for proper venting. Replace if bracket is cracked, broken, or causing loose damper.

Mounting plate for microwave hood combo units. Secures the microwave to wall or cabinet. Replace if bent, cracked, or damaged during installation.

Mounting nut assembly that secures microwave components to studs or brackets. Replace if cracked, stripped, or missing to restore stable panel attachment.

This microswitch senses the microwave door position and controls the safety interlock circuits. Replacing a worn switch restores proper start/stop behavior so the oven only runs when the door is fully closed.

• Detects door open/closed status to enable or disable cooking
• Part of the safety interlock system that stops operation if the door opens mid-cycle
• Replace if the switch fails a continuity check or shows heat or terminal damage

• Disconnect power before service; microwave capacitors can retain a dangerous charge
• Note wire positions and move them to the same terminals on the new switch
• Ensure the door latch cleanly actuates the switch; test operation before reassembly
