Ideal BCC Kit Evomax NG 80 176423

The BCC kit is the control card assembly used on Ideal commercial boilers, supplied under part number 176423. It carries the printed circuit board that acts as the control centre of the appliance, reading inputs from the sensors, thermostats and switches and governing the sequence of operation. It also enforces the boiler's safety protocols, shutting the appliance down when a monitored condition falls outside the permitted range.

• The boiler locks out or fails to fire, with the fault returning after a reset.
• Error or fault codes appear on the display that point to control or sensing faults rather than a mechanical problem.
• The appliance does not respond to a call for heat from the thermostat or programmer.
• The fan, pump or ignition sequence behaves erratically, starting and stopping without a clear demand.
• The board shows visible signs of heat damage, moisture ingress or tracking around the terminals.

• Confirm the GC number and model on the appliance data badge against the compatibility list, as the same boiler family can use different control cards across outputs.
• Check the existing board for the alternative number 1781898 before ordering, so the correct variant is supplied.
• Inspect the board connectors, seals and any gaskets disturbed during removal and replace them if they are perished or damaged.
