The pressure switch monitors negative pressure generated by the inducer motor to confirm proper venting before allowing the ignition sequence to proceed. When it fails or sticks open, the control board receives no confirmation signal and puts the system into lockout — resulting in a no-heat condition with the inducer running but the burners never firing.
