122-607

This professional-grade low-pressure switch is a critical safety component designed for R-410A air conditioning and heat pump systems. It functions as an air-proving and pressure-monitoring device that protects the compressor from damage caused by low refrigerant levels or system leaks. By automatically cycling the system when pressures fall between 107 and 68 PSIG, it prevents the evaporator coil from freezing and ensures the mechanical integrity of the cooling circuit. This durable replacement switch is essential for maintaining efficient operation in residential and light commercial HVAC units, providing reliable system monitoring and preventing costly compressor failures.
