What it is
The Ideal 176842 is a printed circuit board supplied with a CUI replacement, built to the I7/2 specification. It is the main control board for a range of Ideal combi and heat-only appliances, handling ignition sequencing, fan and pump control, temperature monitoring and the safety interlocks that sit behind them. The board is listed under the Ideal Spares brand and is the direct replacement for the earlier 176484 board.
Signs this part needs replacing
- The boiler fails to fire, or locks out repeatedly with no fault found elsewhere in the ignition or gas train
- A blank, flickering or unresponsive display and control panel
- The fan, pump or diverter valve is not being driven when a demand is present
- Intermittent faults that appear or clear when the board or its connectors are disturbed
- Error codes pointing to control, sensor or communication circuits rather than to a physical component
Before you order
- Match the GC number on the appliance data badge against the compatibility list before ordering
- Confirm the board revision: this unit is the I7/2 specification
- Cross-check the previous number 176484 and the alternative number 1781953 against the board being removed
- Isolate the electrical supply and follow the manufacturer's wiring and commissioning instructions when fitting
