What it is
The CABLE - THERMAL FUSE (HEAT EXCHANGER) is a Potterton Commercial spare, part number 7661040. It is the thermal fuse cable associated with the heat exchanger on Potterton Commercial Sirius 2 and Sirius 3 boilers, forming the overheat cut-out link in that circuit.
Signs this part needs replacing
- The boiler locks out or fails to fire, with the thermal fuse link open circuit.
- No continuity is measured through the fuse cable when tested.
- Repeated overheat faults traced to the heat exchanger fuse link.
- Visible damage to the cable or fuse body, such as brittle or discoloured insulation.
Before you order
- Confirm the boiler model against the Sirius 2 or Sirius 3 listings above.
- Check that the part number on the existing cable matches 7661040.
- Verify the fault lies with the heat exchanger thermal fuse cable rather than another sensor or lead on the appliance.
