What it is

The Johnson & Starley low voltage harness, part 1000-0523280, is a wiring loom used on Johnson & Starley RENO boilers. It carries low voltage control signals between the boiler's electrical components. It is supplied as a complete harness assembly.

Signs this part needs replacing

  • Intermittent operation, or faults that change when the loom is moved
  • Cracked, brittle or heat-damaged insulation along the harness
  • Corroded, loose or discoloured connector terminals
  • Boiler failing to power up, or controls not responding
  • Repeated fault codes traced back to the control circuit

Before you order

  • Confirm the appliance is a RENO 16H, 25H or 31H
  • Check the part number on the existing harness against 1000-0523280
  • Inspect the connector type and pin count on the existing loom
  • Isolate the appliance from the electrical supply before fitting
