What it is

The Ideal 175904 is a mechanical timer insert for Ideal Independent boilers. It sits in the appliance's control fascia and provides the clock and switching function, bringing the boiler on and off to the times set on the dial. It is supplied as a replacement insert rather than a complete fascia assembly.

Signs this part needs replacing

  • The timer dial no longer advances, so the boiler stays on the same setting.
  • The clock loses time or stops altogether, drifting away from the set programme.
  • The boiler fails to fire at the programmed on times, or continues running past the off times.
  • The timer feels loose, stiff or does not click positively between positions.
  • Heating and hot water run continuously because the switched output stays live.

Before you order

  • Check the model and GC number on the appliance data badge against the compatibility list before ordering.
  • Confirm the existing timer carries the number 175904 or 1781564.
  • Inspect the fascia and any retaining clips for damage while the insert is removed.
