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.
 

A replacement board supporter that secures the appliance control board to the cabinet, helping keep the board stable and positioned away from wiring and chassis. Restores proper mounting to reduce vibration and movement of the control board. What it does:

• Holds and supports the control/PC board to prevent excessive movement or rattling
• Keeps the board spaced from the chassis and wiring to reduce risk of shorting or contact
• Helps maintain stable electrical connections for reliable control operation
• Reduces noise caused by a loose or vibrating control board
• Can prevent further wear on board mounting points and connectors

• Disconnect power to the appliance before beginning any service.
• Handle the control board by its edges and avoid touching components; use ESD precautions if available.
• Remove nearby panels or components as needed for access; retain all fasteners for reassembly.
• If mounting points or fasteners are damaged, inspect nearby parts and replace as required.
