What it is

The TF836.3 is a control box manufactured by EOGB for use within its Honeywell and Satronic appliance range. It forms part of the boiler's control assembly, handling the switching and sequence functions the appliance relies on to run.

Signs this part needs replacing

  • The boiler fails to fire or complete its start sequence on a call for heat.
  • The appliance repeatedly goes to lockout and needs manual resetting.
  • Ignition or burner operation is intermittent rather than consistent.
  • The boiler shows no response to the thermostat or programmer.
  • Visible damage, moisture ingress or burning at the control box.

Before you order

  • Confirm the control box reference on the existing unit matches TF836.3.
  • Check the appliance make and range against the fitment information above.
  • Verify the fault lies with the control box rather than the ignition, sensor or gas-side components before replacing.
  • Isolate the electrical supply to the appliance before removing or fitting any control component.
