Pressure switches are safety devices that monitor refrigerant pressure on both the high and low sides of the refrigerant circuit. When either switch detects an out-of-range pressure condition — caused by low refrigerant, a blocked condenser coil, or a faulty compressor — it opens the control circuit and shuts the system down to prevent compressor damage. Common failure symptoms include the system locking out on startup, the compressor cutting off prematurely, or fault codes indicating a pressure trip on your thermostat or control board.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e High Pressure Switch — OEM Part 312926-252 | Low Pressure Switch — OEM Part 312926-258 | Factory-calibrated cut-out and cut-in pressure ratings | Spade terminal connections | Designed for R-410A refrigerant systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM pressure switches are factory-calibrated to exact cut-out and cut-in pressure thresholds for the CH13NA01900GABAA.

Tools needed: refrigerant recovery machine, manifold gauge set, adjustable wrench, multimeter, and Schrader valve core tool. Low-side switch replacement is more accessible but still requires system depressurization. Always verify the system is de-energized before beginning work.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty on both switches.
