The pressure switch monitors the inducer blower's vacuum to confirm that combustion gases are being safely vented before allowing the furnace to proceed to ignition. When this switch fails or sticks open, the furnace will lock out before the ignition stage — a common symptom being a running inducer motor with no burner flame and a fault code indicating a pressure switch error. Note: HK06WC091 has been superseded; the current OEM replacement is \u003cstrong\u003eHK06MC110\u003c\/strong\u003e.
