The pressure switch or safety switch monitors system pressure within the refrigerant circuit. If pressure exceeds or falls below safe thresholds — due to a refrigerant leak, blockage, or compressor fault — the switch cuts power to protect the compressor from damage.
Signs It Has Failed
- Compressor shuts off unexpectedly despite no overheating
- Fridge fails to restart after power cycling
- Error code related to pressure or cooling circuit

DIY Difficulty
High. Involves the refrigerant circuit — a certified technician is required in most jurisdictions. Do not attempt to bypass a pressure switch; it is a critical safety component.
