Ideal Printed Circuit Board BCC Card Logic 18 175957

The Ideal 175957 is a printed circuit board (PCB) supplied as a BCC card kit for the Logic range of boilers. It is the central control board, monitoring and governing every process in the appliance through the sensors, switches and thermostats connected to it, and it enforces the boiler's safety routines. This board is listed for Logic, Logic Heat and Logic System 18 models, including Ideal Commercial applications.

• The boiler goes to lockout or shows a fault code that points to the control board
• No display, no response to the controls, or the boiler will not attempt to fire
• The fan, pump or ignition sequence fails to run when there is a call for heat
• Intermittent or erratic operation that does not trace back to a sensor, switch or thermostat
• Visible damage, moisture tracking or burning on the board itself

• Check the GC number on the appliance data badge against the numbers listed above before ordering
• Confirm the model name and, where relevant, the serial number, as the Logic, Logic Heat and Logic System variants use different board configurations
• Cross-check the alternative number 1781626 if you are matching against an older listing
• Work on the boiler controls should be carried out by a competent person, with the appliance isolated and made safe first
