When your GE or Monogram refrigerator's compressor stops running, the inverter board is the first component to suspect. A failed inverter board cuts power to the compressor, causing the fridge to warm up silently — no noise, no cooling, no warning. Part WG03F07266 is the OEM-spec inverter board that restores compressor operation and gets your refrigerator back to temperature.
Symptoms of a Failed Inverter Board
- Refrigerator not cooling but lights and fans still work
- Compressor not starting or running intermittently
- Fridge runs warm while freezer stays cold
- Clicking or relay-cycling sounds near the compressor
- Error codes related to compressor or sealed system on display

The inverter board and compressor hall sensor fail together more often than not. If you're already pulling the board, inspect the hall sensor (typically clipped to the compressor body). Replacing both in one service call eliminates a costly second labour visit — and the hall sensor is a fraction of the board cost.
Installation Notes
- Skill Level: Intermediate — requires access to the compressor compartment (rear or bottom panel removal)
- Disconnect power before beginning any work
- Photograph existing wiring harness connections before removal
- No torque-sensitive fasteners; standard Phillips and 1/4" hex driver required
- Allow refrigerator to stabilize for 2–4 hours after repair before loading food
