What it is
The Ideal 176989 is a wiring harness that links the timer and external control circuit to the appliance's main PCB. It carries the low-voltage switching signals between the programmer, room thermostat or external control input and the boiler's control board. The harness is supplied by Ideal for use across the Logic+ Combi range and Ideal Commercial appliances.
Signs this part needs replacing
- The programmer or external control has no effect on heating or hot water demand
- Intermittent operation when the timer calls for heat, with the boiler failing to respond
- Visible damage to the loom, such as chafed, burnt or brittle conductors
- Loose or corroded plug terminals at the PCB or control end
- Fault codes or lockouts that appear only when an external control is connected
Before you order
- Check the GC number and serial plate on the appliance to confirm the model before ordering
- Confirm the existing harness carries the number 176989 or the alternative number 1777705
- Inspect the control plug and PCB socket for damage, as a worn connector can mimic a faulty harness
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
