How Pressure Switches Work
Pressure switches in heating equipment monitor the negative pressure (draft) created by the inducer blower motor. When the inducer establishes the correct airflow, the pressure switch closes, signaling the control board to proceed with ignition. If pressure falls outside the acceptable range — such as from a blocked flue, failed inducer, or cracked heat exchanger — the switch remains open, locking out the system and preventing hazardous operation.
