What it is

The 1000-0523370 is a low voltage wiring assembly (harness) manufactured by Johnson & Starley for use in its Reno range of gas boilers. It carries low voltage control and signal connections between the boiler's electrical components. It is supplied as a complete harness assembly for service and repair work.

Signs this part needs replacing

  • Intermittent boiler operation or faults that come and go when the harness is moved
  • The boiler fails to respond to controls or sensors connected through the harness
  • Visible damage to the harness, such as chafed, cracked or heat-affected insulation
  • Loose, corroded or discoloured connector terminals at either end of the assembly
  • Repeated electrical or communication-related fault codes traced to the low voltage circuit

Before you order

  • Confirm your appliance is a Johnson & Starley Reno 30C or Reno 37C
  • Check the part number on the existing harness against 1000-0523370
  • Inspect connector types and pin layout on the existing assembly before removal
  • Isolate the electrical supply to the boiler before fitting
