The low pressure switch continuously monitors refrigerant pressure on the suction side of the refrigerant circuit. When system pressure drops below the factory-set threshold, the switch opens the control circuit, preventing the compressor from operating under dangerous low-refrigerant or low-pressure conditions. A failed pressure switch commonly causes symptoms including compressor lockout, a system that trips immediately on startup, or an error code indicating a low-pressure fault on the control board.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 55-23# pressure rating | Factory-set cut-out at low pressure | Brass inlet connector | Precision-calibrated diaphragm | Pre-wired color-coded leads for fast installation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM switch is factory-calibrated to exact cut-in\/cut-out pressure specifications for the PH16NC03600GBAAA.
