The Relay Board is an OEM part for GE microwaves. It controls the passage of proper voltage levels for various microwave components during operation.

Installed internally, this board transmits power signals to run the magnetron, fan, and lighting systems as directed by the selected cooking settings. Precise switching of voltages is required for consistent and balanced microwave radiation. 

Symptoms of a faulty relay board include:  

• Intermittent or unpredictable power level adjustments
• Magnetron fails to turn on or fluctuates excessively
• Light not illuminating properly  
• Fan speed irregularities
• Microwaves not properly heating foods

Causes can be damage from liquid intrusion, heavy usage over time stressing the relays, or component failures within the board itself.

Replacing with this genuine OEM GE part restores optimized power routing to maintain consistent microwave functions. Compatible models also include some Hotpoint, RCA, and select Kenmore products.
 

This small button fits into the microwave door handle to cover the mounting screw opening, restoring a clean, factory look. Replace a missing or damaged button to refresh appearance and help keep the handle area tidy.

• Covers the handle's mounting screw opening for a finished appearance
• Helps keep debris out of the handle cavity
• Replaces a lost, cracked, or discolored button
• Common signs include a missing cap, visible screw, or a loose/broken button

• Disconnect power before servicing any microwave
• Gently pry out the old button; avoid scratching the handle—use a plastic tool if needed
• Align the new button with the opening and press until fully seated
• If your model requires door disassembly, microwaves can retain high voltage.

This smart board is the electronic control module that manages oven functions, the front display, and user inputs so your range responds correctly to temperature and timer settings. Replace a failed control board to restore normal oven control and display functions. What it does

• Controls oven temperature regulation, bake/broil cycles, timers and clock functions
• Manages touchpad/display inputs and on-screen error messaging
• Coordinates safety interlocks and sequencing for heating elements and igniters
• Malfunction can cause blank or incorrect display, unresponsive controls, or ovens that won't start heating

• Disconnect power at the breaker or unplug the appliance before servicing
• Handle the board carefully to avoid static discharge; use antistatic precautions if available
• Verify wiring and connector seating during install; replace only with the exact part number

This electronic control board manages oven functions and the user interface so the range can run timed cycles and temperature commands reliably. Replacing a faulty board restores control and display operation for affected bake/oven features. What it does:

• Receives input from the console and sends commands to heating elements, igniters, and timers
• Controls oven temperature regulation and cycle timing based on user settings
• Can cause symptoms like a blank or unresponsive display, no heating, incorrect oven cycles, or error codes when failing
• Works as the central logic module for oven/range electronic control

• One electronic control board

• Always disconnect power at the breaker or unplug the appliance before service
• Handle the board carefully to avoid static damage; use anti-static precautions if available
• Verify wiring connections and mounting are secure; replace only with the exact part number
• Test function after installation; for any required control calibrations

Fix a microwave with a non-working display, unresponsive buttons, or vent fan stuck on high. This control board restores keypad and timer functionality.
