What it is
The Potterton Stat/Ignitor/Valve Wiring harness carries the electrical connections between the safety thermostat, igniter, gas valve and pressure switch circuits on Potterton Commercial Sirius 2 boilers. It is supplied under part number 5141595 and sits within the gas boiler spares range as a wiring assembly. The harness restores correct signal routing to the ignition and gas control components once the existing wiring is damaged or intermittent.
Signs this part needs replacing
- Intermittent or failed ignition despite the igniter and gas valve being serviceable
- Boiler locking out or dropping out when the wiring is disturbed or the casing is refitted
- Brittle, discoloured or heat-damaged insulation on the harness conductors
- Corroded, loose or pushed-back terminals at the safety thermostat, gas valve or pressure switch plugs
- Repeated electrical faults traced to open or high-resistance continuity in the harness
Before you order
- Confirm the boiler model on the appliance data plate is a Sirius 2 WH90 or WH110
- Check the existing harness part number against 5141595 before ordering
- Inspect connector types and plug positions on the original harness so the replacement matches
- Isolate the electrical supply and gas supply before any work on the boiler wiring
