What it is
This is a boiler wiring harness, part number 7661041, from Potterton Commercial. It connects the safety thermostat, igniter, gas valve and pressure switch on Potterton Commercial Sirius 2 and Sirius 3 commercial boilers. The harness carries the control and safety signals between these components and the boiler's control system.
Signs this part needs replacing
- Frayed, cracked or heat-damaged insulation along the harness
- Intermittent ignition or repeated failure to light
- Boiler lockout or flame failure faults traced to the safety thermostat circuit
- Gas valve or pressure switch faults caused by a break in continuity through the harness
- Loose, corroded or discoloured connector terminals at the igniter or gas valve
Before you order
- Confirm the boiler model, and on Sirius 2 units whether the appliance dates from April 2016
- Check the part number on the existing harness against 7661041
- Compare the connector layout and plug count on the existing harness with the replacement
- Inspect the connector terminals for corrosion, as this may point to a fault elsewhere in the circuit
