The pressure switch proves that the draft inducer motor has established proper negative pressure inside the heat exchanger before allowing ignition to proceed. When it fails or sticks, the control board cannot confirm safe venting conditions and will lock out the system — resulting in a no-heat call with no spark or ignition attempt. Common symptoms include a furnace that cycles the inducer but never advances to ignition, or a system that throws a pressure switch fault code.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 0.18\" WC (water column) set point | SPST (Single-Pole, Single-Throw) | Replaces OEM part HK06WC061 and current supersession HK06MB061 | Also cross-references Honeywell IS20224-5236\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM pressure switches are calibrated to exact factory water-column tolerances (±0.01\" WC).
