The pressure switch is a critical safety component that monitors the inducer motor's draft pressure to confirm proper venting before allowing the ignition sequence to begin. When the switch fails — whether stuck open or closed — the control board cannot verify safe combustion conditions, resulting in a no-heat lockout condition. Common symptoms include the inducer motor running continuously with no ignition attempt, a flashing fault code indicating a pressure switch error, or the system failing to advance past the pre-purge cycle.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Replaces OEM part numbers \u003cstrong\u003eHK02ZA442\u003c\/strong\u003e (High Pressure Switch) and \u003cstrong\u003eHK02ZB044\u003c\/strong\u003e (Pressure Switch) | Factory-calibrated W.C.

Aftermarket pressure switches frequently carry wider calibration tolerances, leading to nuisance lockouts or — more dangerously — failure to detect true venting problems.
