The pressure switch monitors the pressure differential created by the inducer\/draft blower to verify safe venting conditions before allowing ignition. When the switch fails — or when the diaphragm stiffens due to age — the furnace will lock out before the ignition sequence begins, leaving you with no heat. A failed switch is one of the most common no-heat diagnoses on Carrier packaged gas equipment.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e LP Gas Pressure Switch | Cut-out pressure: 6.5\" WC | SPST normally open | Compatible with Carrier, Bryant, and Payne platforms | OEM Part Numbers: HK02LB008 (Gas Pressure Switch) and HK06WC091 (Pressure Switch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM pressure switches are calibrated to exact factory cut-out tolerances.
