How to check if ref. I39845845 is the part for your boiler
What determines it is not the boiler model, but the reference printed on the part you already have installed.
- Find the reference printed on the installed part and check whether it matches the catalogue reference I39845845. If it is not visible, do not identify the part from its shape alone.
- Check the full boiler model on its data plate and look for it in the model associations on this page.
- Compare the connections and physical body with the original part before installation.
- If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Symptoms and faults that the PCB I39845845 resolves.
The PCB controls the ignition, modulation, and safety features of the boiler. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler does not start even though the thermostat is calling for heat.
Cause: The control module does not receive or interpret the signal from the thermostat.
Measure the continuity of the thermostat wiring to the terminal block on the PCB with a multimeter before replacing the module.
- 02
The boiler randomly locks out and needs to be manually reset.
Cause: The module loses the reference of one of the sensors and interrupts the cycle for safety reasons.
Note the time and active demand, heating or domestic hot water, each time it locks up, to identify if there is a specific sensor involved.
- 03
The boiler works but does not modulate; it always runs at maximum power.
Cause: The module does not correctly manage the modulation signal, although it keeps the ignition on.
Check the flow sensor or the flame sensor before concluding that the entire module is faulty.
- 04
The control or the panel cannot change any parameter of the boiler.
Cause: The module does not process communication with the control, although the rest of the boiler functions normally.
Cut the power to the boiler for 30 seconds; if the control still does not respond after the reset, the fault is in the module.
Fault codes for Ferroli that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| A61 | Control board anomaly: internal error of the ABM03 electronic control board (the PCB itself). | The ABM03 PCB detects an internal fault in its microprocessor/electronics; the brand's guide indicates checking the grounding and REPLACING the control board if the issue persists. Verify: after checking the grounding connection, if the fault code remains, the cause is the PCB. |
| A63 | Control board anomaly: internal error of the ABM03 control board (the PCB). | Internal fault of the ABM03 control electronics; the official manual indicates checking the earth and replacing the control board if necessary. Verify: once the earth is checked, the persistence of A63 points directly to the PCB. |
| A64 | Control board anomaly: internal error of the ABM03 control board (the PCB). | Same family as A61/A63: internal fault of the ABM03 PCB; documented remedy = check earth and replace control board. Verify: if earth is ruled out, the code confirms PCB fault. |
| A65 | Control board anomaly: internal error of the ABM03 control board (the PCB). | Internal control electronics error ABM03; the official solution is to check the earth and replace the control board. Verify: persistence after checking earth/connection = defective PCB. |
| A02 | Flame signal present with the burner off. | Among the documented causes, the 'control board anomaly' (PCB) is expressly mentioned, in addition to the ionisation electrode; the electronics read non-existent flame. Verify: check the wiring of the ionisation electrode; if the wiring/electrode are correct, the cause is the PCB. |
| A62 | There is no communication between the control board (PCB) and the gas valve. | The ABM03 PCB fails to communicate with the gas valve: causes = control board not connected/control side faulty, or damaged valve. Verify: check the control board-valve wiring; if the valve and connections are ruled out, the communication fault lies with the PCB. |
These symptoms can have more than one cause. If your boiler displays a fault code, send it to us via WhatsApp along with a photo of the labeling, and we'll tell you if this is the part.
