This Main PBA is the refrigerator's primary electronic control board that manages compressor, fans, lights and user interface functions, helping restore normal operation when the board fails. Ideal for replacing a damaged or unresponsive control board. What it does
- Controls compressor, evaporator/condenser fans and defrost/drain cycles to regulate cooling.
- Manages front-panel display and user input signals.
- Can resolve symptoms like no cooling, dead display, intermittent compressor operation, or failure to respond to controls.
- Works as the central logic board coordinating timing and sensor signals.
What's included
- One Main PBA (electronic control board), as shown.
Install notes
