Ideal Printed Circuit Board No.15 060557

The Ideal 060557 is a printed circuit board — designated board No.15 — supplied by Ideal for its commercial boiler range. It is the control board that governs the appliance's operating sequence, handling inputs from the thermostat, sensors and safety devices and switching the fan, pump and burner train accordingly. The board is a direct replacement item for the original fitted unit and carries the manufacturer's part number 060557.

• The boiler locks out repeatedly, with the fault returning after reset.
• No display, no status LEDs or a dead control panel when the appliance is powered.
• The fan, pump or ignition sequence fails to start even though the demand and supply are present.
• Intermittent shutdowns or erratic behaviour that changes with temperature or vibration.
• Repeated error codes that point to the control board rather than a sensor or switch.

• Confirm the appliance model and GC number against the compatibility list before ordering.
• Check the board number printed on the existing PCB — this item is board No.15.
• Compare the numbers on the removed board with 1171061 and 404401 to confirm you are replacing like for like.
• Work on the appliance only with the electrical supply isolated, and follow the manufacturer's wiring and commissioning instructions on refit.
