What it is

The Worcester Bosch 8737603346 control box housing with PCB is the combined enclosure and printed circuit board assembly used on Worcester Bosch Greenstar 2000 Combi and Gr2300IW appliances. It carries the control electronics and provides the mounting and connection point for the appliance wiring within the casing. The housing and board are supplied together as one unit.

Signs this part needs replacing

  • No power or no response at the appliance control panel
  • Repeated lockouts or fault codes traced to the control board
  • Visible scorching, burning or tracking on the PCB
  • Cracked or heat-damaged housing around the board
  • Loose, corroded or heat-affected connections at the control box terminals

Before you order

  • Confirm the appliance model against the fit list above before ordering
  • Check whether the fault lies with the board or the housing, as both are supplied together
  • Inspect the existing control box and its plug connections for damage
  • Have the appliance model and part number to hand when ordering
