The pressure switch monitors gas supply pressure and opens or closes the control circuit when the detected pressure crosses its factory-set threshold. When this switch fails, the furnace or packaged unit will typically lock out on a pressure fault — refusing to initiate a heating cycle even though the inducer motor is running. This is the correct OEM part to restore reliable ignition sequencing.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Cut-out pressure 6.5\" W.C. | Suitable for LP gas applications | SPST normally-open contacts | Can be mounted horizontally or vertically | OEM part numbers: HK02LB008, HK06WC091, HK06WC100 (w\/ bracket)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the genuine Carrier OEM switch, factory-calibrated to the exact 6.5\" W.C. setpoint.
