Ferroli Domicompact F30B PCB Ref. 39812370
The Ferroli Domicompact F30B PCB (control board) Ref. 39812370 is a component manufactured by Honeywell that controls the ignition, burner modulation, pump, and safety features of the boiler. When it fails, the boiler may not start, become locked, or exhibit erratic behavior, which can generate the fault code F04: Anomaly of the board parameters. This board is compatible with the Domicompact F24B, F24D, F30B, and F30D models, among others. It is recommended to replace the board when it shows faults in its operation or when the mentioned symptoms become evident.

How to check if the reference 39812370 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 39812370. 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 39812370 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 ignite and there is no apparent mechanical cause.
Cause: If you have checked that the gas, water, and pressure are correct, the problem may be with the PCB, which is the one that controls the ignition.
Make sure that there is correct water pressure and that the gas valve is open; if everything is fine and the boiler still does not ignite, it is likely that the PCB is failing.
- 02
It does not respond to the control panel commands.
Cause: The PCB is responsible for receiving and processing the commands from the panel; if the input circuit fails, the buttons will not work even if the boiler is operational.
Turn off and on the boiler from the main switch and wait a minute: if it does not respond to any button, the PCB could be the cause.
- 03
A control fault appears on the display for no clear reason.
Cause: The PCB can detect inconsistencies in its readings or in internal communication and mark it as a control fault, different from faults related to the sensor or pressure switch.
Note the exact code and compare it with the specific codes for sensor, pressure switch, or flame in the manual: only if it matches 'PCB fault' should you consider replacing it.
- 04
Intermittent lockouts of the boiler
Cause: An intermittent fault on the PCB, such as a solder joint or a component damaged by temperature, can cause random lockouts without a clear pattern.
Record when the blockages occur (cold start, after several hours, with hot water) to identify if there is a pattern that indicates another problem before changing the PCB.
Fault codes for Ferroli that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F04 | Anomaly in the parameters of the PCB (control board). | The MF08F.1 control PCB stores the configuration; if there are corrupt or improperly programmed parameters, the board itself triggers F04. Check by entering the service menu and reviewing/adjusting the parameters; if it does not accept programming or the fault persists, replace the PCB Ref. 39812370. |
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.
