Ideal BCC Card Kit Evomax NG150 176426

The Ideal 176426 is a BCC card kit, a printed circuit board assembly used in Ideal Heating commercial boiler controls. It sits within the electronics and controls group of Ideal commercial spares and is supplied as a single-piece kit. The board handles the boiler control function on the appliances it is listed against, working alongside the rest of the control and ignition sequence.

• The boiler locks out or fails to complete its ignition sequence, with the fault recurring after a reset.
• Fault codes relating to the control board appear on the appliance display and will not clear.
• The fan, pump or gas valve does not respond when the boiler is called for heat.
• Visible damage on the board itself, such as scorching, discoloured tracks or bulging components.
• Intermittent operation, where the boiler runs correctly for a period and then drops out without an obvious external cause.

• Confirm the appliance model and GC number from the data plate before ordering, as the board is listed against specific Evomax and Instinct Heat variants.
• Check the existing board against the part number 176426 and the alternative number 1781904 to make sure the correct revision is being replaced.
• Isolate the electrical supply at the fused spur and follow the manufacturer's wiring and commissioning instructions when fitting a replacement control board.
