GE models: Most GE side-by-side and French-door models have condenser coils at the back; top-freezer models typically have coils underneath. The tech sheet is behind the bottom storage drawer. GE Profile and Café models support self-diagnostics from the control panel.
Common causes
- Compressor overheating due to dirty condenser coils
- Compressor start relay failing
- Compressor at end of life
Step-by-step fix
- Clean the condenser coils thoroughly.
- Allow the compressor to cool for 30 minutes, then restore power.
- Listen for the compressor start — a clicking sound that repeats every few minutes without the compressor running points to a failed start relay.
- Test the start relay (shake it — a loose rattle indicates failure).
