Parts for HMV1472BHS: Oven Cavity Parts

This magnetron is the microwave's high-voltage tube that produces the microwaves used for cooking. Replacing a failing magnetron restores heating performance and stops cold or weakly heating cycles. What it does:

• Converts high-voltage electrical energy into microwave radiation to heat food
• Common symptom: microwave runs but does not heat or heats weakly
• May also cause loud humming, arcing, or burning smells when failing
• Works with the oven's high-voltage circuit and waveguide to deliver microwave energy

• Disconnect power and unplug the appliance before servicing
• The high-voltage capacitor can retain a dangerous charge—discharge before touching components
• Do not operate the microwave without the protective cover and proper grounding in place

The High Voltage Diode is an OEM replacement part for GE microwaves. It converts the high voltage of the microwave's power supply into a lower voltage suitable for the magnetron. It acts as a one-way valve for electrical current, allowing it to flow in one direction while preventing it from flowing back in the opposite direction.

Symptoms of a faulty high voltage diode include:

• No power or complete loss of power to the microwave
• Inconsistent or inadequate heating performance
• Unusual electrical smells during operation

A bad high voltage diode can occur due to electrical malfunctions, power surges, or excessive heat exposure. If you notice issues such as no power, uneven heating, or unusual electrical smells coming from the microwave, it may be time to replace the old or damaged high voltage diode with this genuine OEM part.

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

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

• 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

The Microwave Thermostat is an OEM part for GE Countertop Microwaves. It is a critical component that monitors the microwave's internal temperature to ensure safe operation. 

Causes of a bad thermostat can include failure of internal components due to prolonged heat exposure during cooking cycles over many years of use. Steam and splatters introduced into the microwave from heated foods can also damage sensors.

Symptoms of a bad thermostat include:

• Inability to heat or reheat foods adequately 
• Short cycling of the microwave interior lights 
• Erratic power levels during cook functions
• Overheating errors or shutoffs for safety

This replacement thermostat is also compatible with RCA and some Kenmore countertop microwave models.

This temperature-sensitive thermostat helps protect the microwave and nearby components by switching the circuit based on heat. It typically engages the cooling/vent fan or opens the circuit if excessive heat is detected, preventing overheating damage.

• Monitors temperature and changes state around the 70°C/40°C range
• Helps prevent overheating of internal components during heavy cooking
• Can trigger or regulate the vent/cooling fan on over-the-range units
• Common failure signs: vent fan not auto-cycling with cooktop heat, microwave shutting off from heat, or no continuity when tested at room temp and when heated

• Disconnect power to the appliance before servicing
• Note wire positions; transfer leads one at a time to the new thermostat
• Mount firmly to its bracket or surface for correct heat sensing
• After installation, verify fan operation and monitor for proper cycling

The Latch Support is an OEM part for GE microwaves. It is a component that helps guide and secure the latch mechanism as it fastens the microwave door closed.

Causes of bad latch support include normal wear and tear from repeated door openings and closings, damage from excessive force applied to the door, or failure of stabilizing clips or mounts.

Symptoms of a bad latch support include:  

• The latch catching or sticking during opening/closing  
• Difficulty fully engaging or disengaging the latch
• Noise or vibration emanating from the latch area
• Misalignment or wobbling of the door in the closed position

This OEM GE replacement part is also compatible with Hotpoint, RCA and select Kenmore microwave models.

The Interlock Switch Lever is an OEM part for GE microwaves. This mechanical component works with the microwave door interlock switch to disable power to the unit when the door is open.

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.

The Charcoal Filter is an OEM part for GE microwave ovens. This component is crucial for absorbing odors and filtering out grease and other contaminants from the air circulated by the microwave's exhaust system. By maintaining a cleaner airflow, the charcoal filter ensures that your microwave remains efficient and free from odors that can affect the taste and smell of your food. The filter measures about 10 inches wide by 2-1/2 inches high.

Causes of a bad charcoal filter include saturation with grease or odors over time, which reduces its efficacy. Additionally, accidental damage or prolonged use without replacement can impair its ability to filter air effectively.

Symptoms of a bad charcoal filter include:

• Persistent odors even after cooking has completed
• Visible grease buildup on the filter
•  Reduced efficiency in air recirculation

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

The Grease Filter is an OEM part for GE range hoods and microwaves. It captures grease and other airborne particles generated during cooking, preventing them from accumulating in the appliance and ductwork. This filter helps maintain the efficiency of the exhaust system and reduces the risk of grease fires.

Over time, the filter can become saturated with grease and other residues, reducing its effectiveness and potentially causing odors or airflow issues.

Symptoms of a bad grease filter include:

• Reduced airflow or ventilation performance
• Persistent cooking odors
• Visible grease buildup on the filter
• The filter appearing damaged or worn

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