What it is

The CN1 9-pole cable connector is a wiring plug supplied by Sime for use in its domestic boiler range. It joins multi-core cable runs within the appliance, carrying control and sensor signals between the boiler's electrical components. It is a service part intended for like-for-like replacement on the models listed below.

Signs this part needs replacing

  • Connector body cracked, brittle or heat-damaged
  • Terminals corroded, discoloured or showing signs of arcing
  • Loose fit on the mating plug, causing intermittent faults or lockouts
  • Individual pins pushed back or failing to latch in the housing
  • Wiring faults traced to a poor contact at the CN1 connection

Before you order

  • Confirm the appliance model and serial number against the fit list above
  • Check the existing connector for pole count and CN1 marking
  • Inspect the mating plug and loom for damage before fitting a replacement
  • Isolate the boiler electrically before removing or refitting any connector
