What it is
The Johnson & Starley 1000-0523405 is the CVBC (ESYS) main ignition and control printed circuit board used on the Reno family of gas boilers. It handles ignition sequencing alongside the boiler's main control functions. It is listed under Controls within gas boiler spares.
Signs this part needs replacing

- Repeated lockouts or fault codes that return after a reset
- Intermittent firing, or the boiler dropping out part-way through a cycle
- No response to heating or hot water demand
- Visible scorching, burn marks or other damage on the board
Before you order
- Confirm the boiler model and GC number against the manufacturer's parts list
- Check the part number printed on the existing board matches 1000-0523405
- Identify whether the boiler is natural gas or propane, as fitment differs across the range
- Isolate the electrical supply before removing the existing board
