Pressure switches monitor refrigerant pressures on both the high and low sides of the refrigeration circuit, sending a signal to the control board to protect the compressor from operating outside safe pressure limits. When either switch fails, the system will typically lock out on a fault code, short-cycle, or refuse to start entirely — leaving your customers with no cooling and a flashing diagnostic LED.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 312926-252 — High-Side Pressure Switch | 312926-258 — Low-Side Pressure Switch | Factory-calibrated trip points | SPST normally-open\/normally-closed configuration matched to OEM specifications | Compatible with R-410A refrigerant systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM pressure switches are calibrated to exact factory trip-point tolerances for the CH13NA06100GBAAA.
