What it is
This is the fan check wiring (fan check lead) for Potterton Commercial gas boilers, supplied under part number 5132574. It carries the fan proving signal between the fan and the boiler control circuit, allowing the appliance to confirm air flow before ignition. The lead is used across the Potterton Commercial Gold and Sirius boiler families.
Signs this part needs replacing
- Boiler locks out or fails to fire because the fan proving signal is not reaching the control board
- Fan runs but the appliance does not progress to ignition
- Intermittent lockouts or nuisance faults that clear on reset
- Visible damage to the lead, such as a broken conductor, scorched insulation or a loose terminal
- Fault code or diagnostic indication pointing to fan or air pressure proving on the relevant Potterton Commercial model
Before you order
- Confirm the boiler model and variant against the fit list above before ordering
- Check the part number 5132574 matches the number on the existing lead or in the appliance documentation
- Inspect the fan and control board connections, as faults attributed to the lead can originate at either end
- Isolate the appliance from the electrical supply before fitting and follow the manufacturer's wiring diagram
