The Baxi 5137532 is a genuine OEM air pressure switch designed for use in selected Baxi, Main, and Potterton boilers. This safety-critical component monitors the correct operation of the fan and flue system by ensuring adequate air movement before allowing the burner to ignite.

If the pressure switch detects insufficient airflow, it prevents ignition to avoid unsafe combustion conditions. A faulty switch may cause ignition failure, intermittent operation, nuisance lockouts, or airflow-related error codes. Replacing it with this genuine Baxi part restores safe, reliable operation.
