Pressure switches monitor refrigerant pressure on both the high and low sides of the refrigerant circuit. When either switch detects an out-of-range pressure condition, it signals the control board to lock out operation, protecting the compressor from catastrophic damage. A failed or stuck pressure switch commonly causes the system to shut down before completing a heating or cooling cycle, triggering a fault code on the control board. If your PA13ER060000AHAA is short-cycling, refusing to start, or displaying a pressure fault, one or both of these switches is a prime suspect.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e HK02ZA395 — High-Side Pressure Switch | HK02ZB028 — Low-Side Pressure Switch | Factory-calibrated trip points | SPST normally open contacts | 24V control circuit compatible\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM Payne\/Carrier pressure switches are calibrated to exact factory trip-point tolerances.
