Available as the \u003cstrong\u003ehigh pressure switch (HK02ZA395)\u003c\/strong\u003e or \u003cstrong\u003elow pressure switch (HK02ZB028)\u003c\/strong\u003e, these switches monitor refrigerant pressure on the high and low sides of the refrigerant circuit to protect the compressor from operating outside safe pressure limits. When either switch fails or trips, the system will lock out, refuse to start, or cycle off prematurely — commonly misdiagnosed as a thermostat or control board issue.\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 | 24V control circuit compatible | Factory-calibrated cut-out setpoints for R-410A refrigerant systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM pressure switches from Payne (ICP\/Carrier family) are calibrated to exact factory setpoints.
