How It Works
The 79J07 pressure switch opens the circuit when system pressure drops to 150 PSI, halting operation to protect the compressor and refrigerant circuit under low ambient conditions. The switch automatically closes and restores normal operation once system pressure recovers to 275 PSI, providing reliable automatic cycling without manual intervention.
