The draft inducer pressure switch is a normally open, single-pole single-throw (SPST) safety device rated at \u003cstrong\u003e0.18\" water column (WC)\u003c\/strong\u003e. It 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 control board never receives the \"draft proven\" signal — resulting in a no-heat condition, a blinking fault code, or a system lockout before any ignition attempt is made.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 0.18\" WC setpoint | SPST normally open | Replaces OEM part numbers HK06WC061 \u0026amp; current successor HK06MB061 | Also cross-references Honeywell IS20224-5236\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM switches are manufactured to exact setpoint tolerances. Off-brand pressure switches frequently carry ±10–15% variance in trip pressure, which can cause nuisance lockouts or — more dangerously — allow the system to attempt ignition without confirmed draft, a serious safety risk.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Power down the unit at the disconnect before starting.
