Pressure switches prove that the inducer motor is generating adequate draft before allowing ignition to proceed. When either switch fails or sticks open, the control board cannot confirm safe venting conditions and the system locks out before the burners ever fire — leaving you with no heat and often a blinking fault code indicating a pressure switch fault.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 312926-252 — High Pressure Switch | 312926-258 — Low Pressure Switch | Factory-calibrated water column (W.C.) rating | Direct OEM replacement, no modification required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM pressure switches are precision-calibrated to the exact W.C. rating required by your Carrier unit.
