What it is

The S1009000 is a genuine Saunier Duval printed circuit board (PCB) that acts as the control centre of the boiler, monitoring inputs from thermostats, sensors and switches and enforcing the appliance's safety shutdown protocols if a fault reading is detected.

Signs this part needs replacing

  • Boiler locks out or fails to respond to the room thermostat/programmer
  • Display or control panel is blank, frozen or unresponsive to buttons
  • Boiler fires intermittently or drops to fault with no clear cause elsewhere
  • Fault codes persist after other components have been checked

Before you order

  • Confirm the part number printed on your existing card matches S1009000
  • Isolate electrical power before replacing the board
  • Have a Gas Safe registered engineer carry out the replacement and re-commission the boiler
