The pressure switch is a critical safety device that monitors negative pressure created by the inducer draft motor to confirm proper venting before allowing the ignition sequence to proceed. When this switch fails — or the hose, port, or inducer motor connected to it fails — the control board receives no confirmation signal and locks out the system, resulting in a no-heat condition with a pressure switch fault code displayed.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM part number \u003cstrong\u003eHK06WC061\u003c\/strong\u003e | Factory-rated W.C.

Aftermarket pressure switches often use wider tolerance ranges, which can cause nuisance lockouts or — more dangerously — allow ignition under marginal draft conditions. OEM is strongly recommended for this safety-critical component.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Power down the unit completely before servicing. Tools needed: 1\/4\" nut driver, flathead screwdriver, needle-nose pliers. Disconnect the rubber hose and two-wire harness, swap the switch, and confirm the hose is free of cracks or blockages before restarting. Always check the inducer motor and vent path if the new switch immediately faults.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty against defects.
