What it is
This is Sime's main printed circuit board, part number 6301441. It is the boiler's central control, monitoring the thermostats, sensors and switches, and enforcing the safety functions that shut the boiler down if a fault is detected. It supersedes the earlier 6301440 and 6301420 boards.
Signs this part needs replacing
- Boiler will not respond to controls or displays no activity
- Intermittent lockouts with no clear fault pattern
