What it is

The Johnson & Starley 1000-0522930 is a mains wiring harness used on Reno series gas boilers. It carries the mains voltage connections between the boiler's electrical components and the incoming supply. It is supplied as a complete harness assembly.

Signs this part needs replacing

  • Frayed, cracked or heat-damaged insulation on the harness leads
  • Burnt, discoloured or corroded connector plugs or terminals
  • Intermittent power loss or the boiler failing to power up
  • Loose or poor-fitting connections at the boiler's electrical points
  • Visible scorching or arcing marks along the wiring

Before you order

  • Confirm your boiler model is a Reno 30C or Reno 37C
  • Check the existing harness part number and connector layout against the boiler
  • Isolate the mains supply before removing or fitting any wiring
  • Inspect connector types and pin counts to ensure they match the boiler's PCB and components
