Pressure switches are refrigerant-circuit safety devices that monitor system pressure and shut down the compressor when readings fall outside safe operating limits. When either switch fails or trips on a fault condition, the system will lock out, short-cycle, or refuse to start cooling altogether. Common symptoms include the outdoor unit shutting off immediately after startup, a fault code on the control board, or no cooling despite the indoor air handler running normally.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e High Pressure Switch — OEM Part HK02ZA395 | Low Pressure Switch — OEM Part HK02ZB028 | Factory-rated cut-out and cut-in pressure settings matched to R-410A refrigerant circuit | Direct OEM replacement, no field calibration required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM pressure switches use factory-calibrated trip points specific to the PA13NR06000GAEAA refrigerant circuit.
