Fault codes related to this part (not the entire boiler). They usually have more possible causes: first rule out electrodes, wiring/connections, and gas supply. Verified with ≥3 sources.

CodeWhat does it mean?Cause and diagnosis (this part)
A23Anomaly in the parameters of the control board.PCB parameters misconfigured (e.g., after replacing the board or losing calibration); check by entering the service menu and correcting/calibrating the parameters.
A24Anomaly in the parameters of the control board.PCB parameters misconfigured; check and reprogram/calibrate from service. If it reappears, inspect the PCB.
A61ABM03 control board anomaly (internal error).Internal fault of the ABM03 control unit/PCB; check the grounding and power supply. If not resolved after reset/calibration, replace the PCB.
A63ABM03 control board anomaly (internal error).Internal error in the ABM03 PCB/control board; check grounding and, if it persists after reset, replace the board.
A65ABM03 control board anomaly (internal error).Internal fault of the ABM03 controller/PCB; check earth and power supply, and if it does not clear, replace the board.
F64ABM03 control board anomaly (internal error).Internal fault in the ABM03 PCB/control board; confirm correct grounding and stable power supply. If it persists, replace the PCB.
F66ABM03 control board anomaly (internal error).Internal fault of the ABM03 control unit on the PCB; check grounding/electrical noise and, if it persists, replace the board.
How do I know if this PCB is for my boiler?
Verify the reference 39845845 printed and ensure your model is on the list of compatible ones; also compare the connections with the original part. It is a Ferroli piece (ABM03 / Bel Honeywell-SIT controller; rebadge in Cointra).
What is it used for?
The PCB controls the ignition, modulation, sensor readings, and safety features of the boiler.
Is the boiler not igniting, locking out, or is the control board unresponsive?
After ruling out mains voltage, fuse, and connectors, a damaged PCB causes lockouts, blackouts, or erratic display. Repair the external cause before installing the new one.
Which models is it suitable for?
Part shared by various models (see Compatibility). If your model does not appear, send us a photo of the marking and we will confirm it.
Installation and recommendations
After installation, a technician must adjust the service parameters (type of gas, power settings) and check combustion and safety features.
What does refurbished mean and what coverage does it have?
Part removed from a boiler out of service, inspected and tested. Includes 1-year warranty and 14-day return policy. Delivery within 2–4 working days in the EU.
