What it is

The Ideal 179073 is an insert mechanical timer supplied by Ideal as a spare for its domestic and commercial boiler ranges. It sits in the boiler fascia and provides the on/off switching periods that control central heating and hot water operation. The unit is a plug-in insert type, so it is replaced as a complete clock rather than repaired on the bench.

Signs this part needs replacing

  • The boiler runs continuously and ignores the set heating periods.
  • The timer dial does not advance, or advances only when manually turned.
  • The clock loses time or resets after a power interruption.
  • The dial is stiff, gritty or will not hold a switched position.
  • Heating or hot water fails to come on at the programmed times despite the boiler otherwise working.

Before you order

  • Check the GC number on the appliance data badge against the compatibility list, as the same boiler family can use different clock variants.
  • Confirm the model name on the badge matches one of the listed Ideal Independent, Independent + Combi or Ideal Commercial appliances.
  • Note that the number 8904429 may appear on older listings and documentation for the same timer.
