What it is
The cable is a power supply PCB cable, supplied under part number 7660978 and used on Potterton Commercial appliances. It carries the low voltage supply between the power supply PCB (AGU2.550) and the associated boards or connectors within the boiler. It is a manufacturer-specific cable assembly, so the connector types and terminations suit the Potterton Commercial control layout.
Signs this part needs replacing
- The boiler fails to power up or the display stays blank
- Power is intermittent or drops out during operation
- The cable shows chafing, heat damage or a loose crimp at either connector
- The boiler fuse blows repeatedly after a power supply fault
- Connector pins are corroded, discoloured or pushed back in the housing
Before you order
- Confirm 7660978 against the part number in the boiler's installation and service documentation
- Check the appliance model on the data plate — this cable is listed for Sirius 2 WH50, WH60, WH70, WH90 and WH110 units
- Inspect the existing cable and both mating connectors for damage that may have affected the PCB as well
- Verify the cable routing and length against the failed item before fitting
