The pressure switch is a critical safety device that monitors negative air pressure created by the induced draft blower. Once the inducer reaches proper speed and airflow is confirmed, the pressure switch closes its circuit and signals the control board to proceed with ignition. When this switch fails — whether due to a ruptured diaphragm, blocked port, or age-related fatigue — the furnace will lock out before ever attempting ignition, leaving you with no heat and a blinking fault code indicating an open pressure switch.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM part number HK06WC061 | Factory-calibrated W.C.

Generic substitutes with off-spec trip points can cause nuisance lockouts in cold weather or, worse, fail to detect a true blocked flue condition — a serious safety concern.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Power down and lock out the unit before servicing. Disconnect the rubber hose from the inducer port and the two 24V wires from the switch terminals. Inspect the hose for cracks or moisture (a common root cause of switch failure) before installing the new switch. Tools needed: flathead screwdriver, needle-nose pliers, multimeter for continuity verification.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty against defects.
