Baxi Air Pressure Switch 247380 / 5137529 / 5105796 (Pre-Owned)

The air pressure switch checks airflow through the boiler's flue system before ignition begins — if airflow is restricted, the switch prevents the boiler from firing, protecting the appliance from unsafe operation. A faulty switch can cause ignition failure or intermittent lockouts.
