Baxi 5137529 Fan Air Pressure Switch – Compatible with 105E, 80E & Performa Boilers

The Baxi 5137529 Fan Air Pressure Switch supersedes the earlier 247380 Air Pressure Switch and monitors airflow generated by the boiler fan before ignition.

The switch confirms that combustion gases can be safely expelled through the flue system. If the required pressure is not detected, the boiler’s safety controls prevent operation.

A faulty pressure switch may cause ignition failure, boiler lockouts, intermittent operation or fan-related fault codes.
