• The grille is fully seated and clear of the door swing

This charcoal filter is used on microwave ovens to filter grease and other air contaminants during cooking. This filter contains charcoal for added filtering and is not washable. When the filter becomes clogged, it must be removed and replaced. If the air filter is clogged, smoke and fumes will not be cleaned, and the room will fill with odors during cooking. The charcoal filter catches grease spatters, and if greasy foods are cooked often, the filter will need to be changed more often. The filter should be removed and replaced regularly and anytime that it is not working efficiently. Removing the filter does not require tools. Pull the old filter straight out and push the new one in place.This charcoal filter is a silver metallic part that is sold individually. It is designed for use in microwave ovens designed by General Electric.

Restore a secure, comfortable grip for opening and closing the door. This replacement handle brings back safe, easy operation and a clean, factory look when the original handle is cracked, loose, or missing. What it does:

• Provides a sturdy handhold to open and close the door
• Replaces a broken, cracked, or missing handle
• Helps maintain safe, consistent door operation
• Common symptoms: loose or wobbly handle, visible cracking, handle pulled off, cosmetic damage

• 1 door handle

• Disconnect power to the appliance before starting.
• Open the door and support the outer panel while removing interior screws that secure the handle.
• Reuse original mounting hardware; tighten screws evenly without overtightening.
• Verify the door opens, closes, and latches properly before returning to service.

The Grille Vent is an OEM part for GE microwaves. It is designed to cover the vent openings, allowing proper airflow while protecting the internal components of the microwave. The grille vent helps maintain optimal ventilation, ensuring that the microwave operates efficiently by preventing overheating.

You should replace the grille vent if it becomes damaged or clogged. Causes of a bad grille vent can include the accumulation of dust and debris, physical damage from impacts, or wear and tear over time. A compromised grille vent can lead to poor ventilation, affecting the microwave's performance and potentially causing overheating.

Symptoms of a bad grille vent include:

• Reduced airflow or ventilation
• The microwave overheating or shutting down during use
• Visible damage, such as cracks or broken slats
• Accumulation of dust and debris in the vent area

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

The Door Latch Board is an OEM part for GE microwaves. The latch board controls the door latching mechanism that secures the microwave door closed during operation. It works alongside the door interlock switch to initiate the removal of power to the magnetron when the door is opened, for safety during use. 

Symptoms of a bad latch board include: 

• The door not closing and latching properly  
• The microwave operating with the door open
• Error codes or blinking lights related to the door interlock system
• Issues engaging or disengaging the door-locking mechanism

This replacement part is also compatible with Hotpoint and Profile microwaves. 

This high-voltage rectifier diode is used in the microwave's high-voltage circuit. It converts AC to DC so the magnetron can produce heat. A failed diode can cause no heat, loud humming, or a blown fuse when starting. What it does:

• Rectifies high-voltage AC to DC to power the magnetron
• Blocks reverse voltage in the HV circuit
• Common failure symptoms can include: runs but doesn't heat; loud hum then shutdown; line fuse blows at startup

• 1 high-voltage diode

• Unplug the microwave and properly discharge the high-voltage capacitor before servicing—dangerous voltage can remain even when unplugged
• Match diode orientation/polarity to the original and ensure a solid chassis ground connection where used
• Route leads and reinstall any clamps/insulators exactly as found; keep wiring clear of sharp edges and hot components
• If the original diode failed, inspect the HV capacitor and transformer for related issues before reassembly

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

This 30-watt incandescent appliance bulb restores bright, dependable lighting in your microwave so you can clearly see food and the cooktop. Replace a failed lamp to bring back full visibility while cooking. What it does:

• Provides 30-watt illumination as designed by the appliance—interior cavity or cooktop area on select models
• Restores visibility when the original bulb burns out or breaks
• Typical symptoms include no light, dim light, or flickering
• Blackened glass or a broken filament indicates the bulb needs replacement

• One 30-watt incandescent bulb

• Disconnect power at the plug or circuit breaker before servicing
• Allow the bulb and surrounding area to cool before handling
• Access the lamp cover or lens per your owner's manual; remove cover, replace bulb, and reinstall
• Replace only with the wattage and type specified for your model

This is the high-voltage magnetron for a microwave oven. It generates the microwave energy that heats food; replacing a weak or failed magnetron can restore normal cooking performance and resolve "runs but no heat" complaints.

• Generates the RF energy that cooks and heats inside the microwave cavity
• Common fix when the microwave runs but does not heat
• Symptoms can include unusually loud humming/buzzing during operation
• Helps with intermittent heating or a burnt odor from a failing tube

• Disconnect power and safely discharge the high-voltage capacitor before servicing
• Note wire locations; transfer any shielding, brackets, or insulators from the original as required
• Mount securely and ensure correct orientation for proper cooling airflow
• After reassembly, test heating with a cup of water

The Door Latch is an OEM part for GE microwaves. It securely holds the door shut during cooking cycles to contain heat, prevent leaks, and keep small children from accessing the cooking cavity. 

Symptoms of a bad door latch include:

• The door not staying closed properly 
• Gaps appearing around the sealed door 
• Difficulty latching or an insecure feel when closed
• Loose, gritty, or damaged movement of the latch mechanism

Causes of a bad door latch are typically wear over time from repeated use. Exposure to steam and heating elements can also degrade plastic and metal components. An improperly closing door presents potential safety issues by allowing excessive heat to escape.

This genuine GE replacement part is compatible with some Hotpoint, RCA, and Kenmore models as well.

This is a fuse that is used on microwaves. This fuse shuts off the microwave if there happens to be a power surge. This helps prevent damage to the microwave unit and also prevents fires from being started from the power surge. Be sure to unplug the microwave from its power source prior to attempting the replacement of the fuse. The process to replace the fuse is relatively easy and can be completed in about 30 to 60 minutes time.A new fuse may be needed if the microwave will no longer turn on. If the fuse has been blown, it will show scorch marks, and the filament inside will be melted.This fuse is a genuine General Electric part and is an OEM part sourced directly from the manufacturer. It is sold individually. This specific fuse is compatible with microwaves that are manufactured by the General Electric brand.

The Control Panel Asm is an OEM replacement part for GE microwaves. It houses the electronic components and interfaces that allow users to operate the microwave functions.

Causes of a bad control panel assembly include damage from moisture damage, impact or drop damage over time, or failures in the electronic components' circuitry. 

Symptoms of a bad control panel include:

• Failure to illuminate or light up when buttons are pressed
• Inability to set power levels or time functions  
• Unresponsive or non-functioning buttons
• Display not working or flickering 

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