Honeywell PCB Ferroli Domicompact F30 Ref. MF08FA
PCB manufactured by Honeywell, model MF08FA, for Ferroli boilers from the Domicompact (C24, F24, F30) and Ferella Zip (C24, F24) ranges. It is identified by the Honeywell marking and the barcode 10UG16LP3223. It is replaced when the boiler's control board fails.

How to check if ref. 39812110 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 39812110. 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 39812110 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 doesn't turn on at all, neither the indicators nor the display: it's completely dead.
Cause: The PCB is the brain that powers and controls the rest of the components; if it fails, no current reaches anything.
Check that 230V is reaching the input connector of the PCB and that its internal fuse is not blown before declaring it dead.
- 02
The boiler locks out with a fault code that changes or disappears on its own, with no clear relation to any component.
Cause: The electronics misinterpret the signals from the sensor, pressure switch, or flame and cause lockouts without any real physical cause.
Note the exact code and check if it corresponds to a real component (sensor, pressure switch, flame) before replacing the PCB.
- 03
The burner turns on and off in very short cycles, as if something is constantly cutting it off.
Cause: A relay on the PCB that doesn't switch properly gives and removes the ignition command erratically.
Check that the thermostat and temperature sensors provide consistent readings before assuming it is the PCB.
- 04
The control or temperature selector is not responding, even though the boiler has power.
Cause: The microprocessor that manages the buttons or communication with the control has stopped reading the commands.
Try resetting the boiler from the control panel itself and check that the wiring of the control is not loose.
Fault codes for Ferroli that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F1 | There is no burner ignition. | The PCB (MF08FA) may fail in managing the ignition (does not command spark or supply the transformer/gas valve) or in flame detection; check if the PCB delivers voltage to the transformer and the valve during the attempt and if it generates/receives an ionisation signal. |
| F2 | Flame signal present with the burner off. | Fault in the detection stage on the PCB that interprets non-existent ionisation current; confirm by disconnecting the ionisation electrode and checking the signal input on the PCB and the wiring to the electrode/ground. |
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.
