What safety device prevents compressor damage due to high pressure?

The high-pressure switch is designed specifically to monitor the pressure levels within the air conditioning system. When the pressure exceeds a predetermined threshold, this switch activates to shut down the compressor. This is crucial in preventing compressor damage caused by excessive pressure, which can result from various factors such as insufficient refrigerant flow, blocked lines, or system malfunctions. By interrupting the operation of the compressor, the high-pressure switch helps to protect the system from potential failures that could lead to significant repair costs or complete system replacement.

In comparison, other devices like the thermal switch primarily protect against overheating rather than pressure issues, the pressure relief valve is more associated with releasing excess pressure rather than preventing compressor operation, and the surge protector deals with electrical surges, not pressure management. Thus, the high-pressure switch directly addresses the concern of compressor damage due to high pressure effectively.
