What it is

The Ideal 177383 is a control knob with a blank potentiometer fitting, used on Ideal Logic and Logic Code combi boilers. It fits onto the control spindle at the boiler fascia so the user can turn and adjust the setting it operates. Ideal supplies it as a replacement knob for the models listed in the compatibility table.

Signs this part needs replacing

  • The knob is cracked, split or has lost part of its body.
  • The knob turns freely on the spindle without changing the setting.
  • The splines or internal grip have worn, so the knob slips instead of driving the potentiometer.
  • The knob has come off the spindle and will not stay seated.
  • The blanking knob is missing, leaving the control spindle exposed on the fascia.

Before you order

  • Check the GC number on the appliance data badge against the compatibility list before ordering.
  • Confirm the boiler model, as Ideal used this knob across several Logic and Logic Code variants.
  • Older stock may carry the alternative number 8901809.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
