The pressure switch monitors negative pressure created by the inducer blower motor to confirm that the flue path is open and safe before allowing ignition to proceed. When this switch fails — or when it senses insufficient draft — the control board will lock out on a pressure switch fault, leaving you with no heat. Common symptoms include the inducer running but the furnace never advancing to ignition, a blinking fault code indicating a pressure switch error, or the system cycling the inducer repeatedly without progressing to the trial-for-ignition stage.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 0.18\" Water Column (W.C.) setpoint | SPST (Single-Pole, Single-Throw) | Normally Open | OEM Part # HK06WC061 (superseded by HK06MB061) | Replaces Honeywell IS20224-5236\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM pressure switches are calibrated to exact W.C. tolerances at the factory.
