What it is
The Potterton ionisation electrode, part number 5142400, is a flame sensing probe used in Potterton Commercial gas boilers. It sits in the burner flame path and returns a small ionisation current to the control board, which confirms a flame is present and allows the boiler to continue running. It is listed as a gas boiler spare in the electrodes category.
Signs this part needs replacing
- Boiler locks out shortly after ignition because no flame is detected
- Repeated lockouts that clear on reset but return on the next cycle
- Intermittent or failed ignition sequence despite spark and gas being present
- Flame signal lost while running, causing the boiler to shut down
- Visible erosion, cracking or heavy contamination on the probe tip
Before you order
- Confirm the part number 5142400 against the electrode currently fitted
- Check the appliance model against the fit list above
- Compare the probe length, mounting and connector with the part being removed
- Isolate the electrical supply and gas before starting work
