The low pressure switch monitors refrigerant pressure on the low side of the refrigerant circuit and sends a signal to the control board to prevent operation under unsafe pressure conditions. When this switch fails or sticks open, the system will typically lock out, refuse to start a heating or cooling cycle, or trip into fault mode — often displaying a low-pressure fault code on the control board.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Low pressure switch | Factory-calibrated set point | Direct OEM replacement | Part# 312926-258 | Designed for R-410A refrigerant circuit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier part, manufactured to exact factory pressure set-point tolerances.
