The pressure switch is a critical safety component that monitors the negative pressure (vacuum) created by the draft inducer motor before allowing ignition to proceed. When the switch fails — or the inducer fails to create adequate draft — the control board receives no signal and the furnace locks out on a pressure-switch fault, producing a no-heat call. Common symptoms include a flashing fault code, the inducer running but burners never lighting, or repeated restart attempts with no ignition.

Aftermarket pressure switches often carry wider tolerances, risking nuisance lockouts or — more dangerously — allowing ignition under inadequate draft conditions.
