What safety device protects the compressor from overheating?

The high pressure cutoff switch acts as a critical safety device for the compressor by monitoring the pressure within the system. If the pressure exceeds a predetermined level, indicating potential overheating or excessive pressure build-up, the switch automatically shuts down the compressor. This prevents damage due to overheating, which can occur if the compressor continues to run under dangerous conditions. By disengaging the compressor, the high pressure cutoff switch helps maintain system integrity and prolongs the lifespan of the refrigeration unit. This mechanism is essential in ensuring that the compressor operates within safe limits, thereby protecting it from thermal stress that could lead to failure.
