The pressure switch monitors negative pressure created by the inducer motor to confirm proper venting before allowing the ignition sequence to proceed. When this switch fails or sticks open, the furnace will lock out before ignition — you may see a fault code indicating a pressure switch error, or the system will simply fail to light with the inducer running normally.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 0.18\" Water Column (WC) | SPST (Single Pole, Single Throw) | OEM Part # HK06WC061 \/ HK06MB061 | Replaces Honeywell IS20224-5236 | Factory-matched setpoint tolerance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM pressure switches are calibrated to the exact setpoint specified by Carrier engineering.
