What it is

The control box is a Glow-worm printed circuit board assembly supplied under part number 0020208830. It manages the electrical control functions of the boiler, handling the signals that govern ignition, sequencing and appliance operation. It is listed for use across a number of Glow-worm gas boiler ranges.

Signs this part needs replacing

  • The boiler does not respond when a demand is applied, with no display or indicator activity.
  • The appliance locks out repeatedly or fails to complete its start sequence.
  • Controls behave intermittently, with the boiler cutting in and out without a clear external cause.
  • Visible damage to the board, such as scorching, burnt tracks or swollen components.
  • Fault codes relating to the control board are logged and will not clear.

Before you order

  • Confirm your boiler model and GC number against the fitment list above.
  • Check the part number printed on the existing control box matches 0020208830.
  • Establish whether your appliance is the R or S variant, as both appear in the fitment list.
  • Inspect the wiring and connections before condemning the board, as loose plugs can mimic control faults.
