Parts for Ge PVM9179DK2WW: Control Parts

The Main Board is an OEM component specifically designed for GE microwaves. It acts as the central control hub, processing all commands and regulating the critical operations of the microwave. The main board monitors the magnetron tube, controls fan speeds, and facilitates user-friendly programming of cooking presets. 

Symptoms of a bad main board include:

• Magnetron failing to ignite or powering off unexpectedly  
• Inability to set or change cooking times/power levels
• Temperature sensors malfunctioning
• Display/control functions acting erratic or unresponsive
• Microwave not heating or partially operating

Causes can stem from power fluctuations or physical damage over time. 

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