What it is
The Baxi 5137530 is a fan pressure switch produced by Baxi for use in its domestic heating appliances. It senses the pressure change created by the combustion fan and signals the appliance control system once air flow is established. This allows the boiler to confirm that the fan is running correctly before it proceeds through its firing sequence.
Signs this part needs replacing
- The appliance locks out or fails to fire when there is a call for heat
- The fan runs but the boiler does not prove air flow and will not continue to ignition
- Intermittent lockouts that clear after a reset and then return
- Fault codes relating to the fan or air pressure circuit
- Repeated ignition attempts without a sustained flame
Before you order
- Confirm that part number 5137530 matches the label or documentation for your appliance
- Check the appliance GC number and serial number against the compatibility information
- Inspect the fan and flue seals and gaskets while the switch is being replaced, and renew any that are damaged
