What it is

The Sime 6278688 is a 10 pole cable connector manufactured by Lumberg for Sime gas boilers. It provides the multi-pin electrical connection between the boiler's wiring harness and the control components within the Format range. The connector carries the low-voltage control and sensor signals required for correct boiler operation.

Signs this part needs replacing

  • Boiler fails to fire or locks out intermittently due to a broken control signal
  • Fault codes relating to sensor or control circuit continuity
  • Visible scorching, melting or discolouration on the connector housing
  • Loose, corroded or pushed-back pins in the plug body
  • Cracking or brittleness of the plastic housing after heat exposure

Before you order

  • Confirm the boiler model is a Sime Format 100C or Format 80C
  • Check the existing connector for the 10 pole configuration and Lumberg body style
  • Inspect the mating socket and harness pins for damage before fitting a replacement
  • Isolate the electrical supply to the boiler before removing or refitting the connector
