The Microwave Door Switch is an OEM part for GE microwaves, designed to prevent the microwave from operating when the door is open by interrupting the power whenever the door is not securely closed. The door switch is an essential safety feature.

Symptoms of a failing Microwave Door Switch include:

• The microwave not starting or heating
• Running when the door is opened
• Unusual noises when the door is closed  

Causes of a bad Microwave Door Switch can result from repeated opening and closing of the door or slamming that can cause the switch to degrade or become misaligned, leading to intermittent or failure.

This OEM GE part can also be used on Hotpoint, RCA, and Kenmore/Sears appliances. 

The Monitor Switch is an OEM replacement part for GE microwave ovens. Located internally on the turntable control circuit board, this switch monitors rotation of the turntable during cooking cycles.  

Causes of failure involve degradation of the electrical contacts from continuous arcing loads over years of use combined with vibration stresses.

Symptoms of a faulty monitor switch include:

• The turntable no longer rotates or spinning intermittently
• Cooking cycles aborting prematurely with error messages 
• Screeching or grinding noises emanating from beneath cavity
• Visible burnt spots on turntable drive assembly

This genuine GE switch is also compatible with select Hotpoint and RCA models.

The Fuse is an OEM part for GE microwaves. It serves as a safety device designed to protect the microwave from excessive current that can cause overheating and potential fire hazards. When the current flowing through the microwave circuit exceeds a certain level, the fuse blows or breaks, cutting off the power to prevent damage or fire.

Common causes for a fuse to blow include power surges, faulty wiring within the appliance, or the use of microwave inappropriate containers that cause sparks. It is essential to address these issues not only to replace the fuse but also to correct the underlying problems to prevent future failures.

Symptoms of a bad fuse include:

• The microwave suddenly stops working.
• No signs of power or response even when the microwave door is closed and the start button is pressed.

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

The High Voltage Diode is an OEM part for GE microwaves. This high-voltage diode is crucial for converting alternating current (AC) to direct current (DC), enabling the magnetron to generate the microwave energy needed for cooking. Measuring approximately 3-1/2" in length, this diode features a banded side with a #8 ring terminal and a non-banded side with a 1/4" female quick connect.

You should replace the diode-H.V assembly if it becomes faulty due to electrical issues, wear and tear, or physical damage. Continuous exposure to high voltage can cause the diode to deteriorate over time, leading to malfunction.

Symptoms of a bad diode-H.V assembly include:

• The microwave not heating food
• A burning smell or unusual noises during operation
• The microwave shutting off unexpectedly
• Visible damage or burn marks on the diode

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

Turntable glass tray. Color: clear. Size. 11-1/2 inches diameter.

This microwave high-voltage capacitor stores and releases energy in the high-voltage circuit to power the magnetron. Replacing a failed capacitor helps restore proper heating and protects other components in the high-voltage system.

• Works with the transformer and high-voltage diode to supply the magnetron with the required voltage
• Failure may result in the unit running but not heating
• Shorted capacitors can blow the internal fuse or trip a breaker; opens may cause loud humming or buzzing
• Visible swelling or leakage on the capacitor body are common failure signs

• Unplug the microwave; capacitors can retain a dangerous charge even when unplugged—discharge using an appropriate, insulated method before servicing
• Note wire positions and terminal orientation; transfer any mounting hardware from the original part
• Mount securely and route wires to avoid pinching

Replacement thermostat that senses and controls the appliance heating system to restore accurate heating and stable temperature cycles, helping the appliance reach and maintain the set temperature. What it does:

• Senses temperature and signals the heating element or valve to turn on/off to maintain set temperature.
• Commonly linked to symptoms such as failure to reach set temperature, temperature fluctuating or cycling erratically, or continuous heating.
• Works as the temperature-regulation component in the appliance's control pathway to stabilize performance.
• Matches the OEM function for temperature control; use when thermostat diagnostics indicate a failed or inaccurate sensor.

• Disconnect power to the appliance before attempting removal or installation to avoid shock or ignition hazards.
• Handle the sensing element and terminals carefully to avoid damage; ensure secure electrical connections and proper routing of any capillary or sensor lead.
• After installation, test the appliance through a full heat cycle to confirm correct operation.

This turntable motor rotates the microwave's glass tray during cooking. Replacing a worn or seized motor restores smooth, consistent tray movement to help ensure even heating and reliable performance.

• Drives the turntable shaft/coupler to rotate the glass tray during cook cycles
• Helps promote more even cooking and defrosting
• Common symptoms of failure: tray doesn't turn, intermittent or jerky rotation, loud humming/grinding from beneath the cavity

• Disconnect power before servicing; microwaves contain high-voltage components—use caution
• Access is typically from the bottom of the unit; remove the tray and coupler, then the motor's mounting screws, and transfer the wire connections
• Align the motor shaft with the coupler and ensure the tray spins freely before reassembly
• Test with a microwave-safe cup of water to ensure smooth rotation

This door lever is the user-access handle component that lets the appliance door open and latch reliably. It replaces a damaged or broken lever to restore normal door operation and safe access. What it does:

• Provides the handle/lever action needed to open and close the appliance door
• Restores a secure latch action when the original lever is cracked, worn, or broken
• Stops sticking or slipping that can prevent the door from opening smoothly
• Helps prevent further damage to the door assembly by replacing a compromised lever

• Disconnect power to the appliance before beginning any work to avoid shock or injury
• Basic hand tools typically required; access may require removing the door or inner panel
• Inspect surrounding trim and mounting points for damage; replace additional parts if worn

This display window is the replacement clear lens that covers the refrigerator control panel, protecting the electronic display and buttons while keeping the panel visible and clean. Restores a clear, professional-looking control area. What it does:

• Protects the control-board display and touch/buttons from spills, dust, and everyday wear
• Keeps the display readable by preventing scratches, clouding, and surface damage
• Helps maintain a weatherproof seal over the control area to reduce moisture contact
• Replaces cracked, chipped, or discolored lenses that make the panel hard to read

• Always disconnect power to the appliance before starting work to avoid shock or damage
• Typically installs with clips or adhesive after removing the outer control panel; use appropriate trim tools to avoid damage
• Handle the lens carefully to avoid scratches or fingerprints on the interior surface during installation
• Inspect those components separately—this part only replaces the outer lens
