Pressure switches monitor refrigerant circuit pressures on both the high and low sides to protect the compressor from operating outside safe pressure limits. When either switch fails or trips, the system will lock out, refusing to run heating or cooling cycles — often with a fault code pointing to high or low pressure faults on the control board.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Part HK02ZA395 — High Side Pressure Switch | OEM Part HK02ZB028 — Low Side Pressure Switch | Factory-calibrated trip points | 24V control circuit compatible | Spade terminal connectors for direct plug-in replacement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM pressure switches are calibrated to exact factory trip-point specifications for the PA13ER060000ACAA refrigerant circuit.
