Bertelli Divatech Micro F32 PCB Ref. 39820661
The Bertelli Divatech Micro F32 PCB (control board) controls functions such as ignition, burner modulation, the pump, and the safety features of the boiler. If it malfunctions, the boiler may fail to start, become locked, or operate erratically, which can lead to faults such as A02, F04, F05, F07, or A23. It is compatible with models from the Divatech range, such as Divatech C24, Divatech C32, Divatech F24, and Divatech Micro F32, among others. It is recommended to replace it upon noticing these symptoms to avoid issues with the boiler's operation.

How to check if ref. 39820661 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 39820661. 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 39820661 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: there is no display, no relays, and no noise.
Cause: The PCB does not supply power to the circuits, possibly due to a blown fuse or an internal fault.
Measure with the multimeter if there is power at the input of the PCB and check the condition of the fuse before replacing it.
- 02
The display shows a fault code that is not related to the boiler.
Cause: The reading of the sensors on the PCB is damaged and generates false errors.
Compare the code with the manual and measure the component indicated before assuming that the PCB is the cause.
- 03
The boiler ignites, heats up a bit, and then shuts off by itself, without a clear pattern.
Cause: An intermittent fault in the control electronics randomly interrupts the sequence.
Note the exact conditions of each shutdown (domestic hot water, heating, ambient temperature) before replacing the PCB.
- 04
Neither the remote control nor the thermostat can get the boiler to respond.
Cause: Communication between the PCB and the external demand system has been lost.
Try to activate the manual mode directly on the boiler to check if it responds without the remote control.
Fault codes for Ferroli that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| A02 | Flame signal present with burner off | The PCB may falsify the ionisation reading (detection circuit on the board), maintaining a flame signal without combustion. Verify by measuring ionisation current and testing with the electrode/cable disconnected; if it persists, reprogram or replace the board. |
| F04 | Anomaly in the parameters of the control board | Corrupted or incorrectly set parameters of the PCB (EEPROM/configuration) after replacement or loss of programming. Verify and reprogram service parameters; if it does not save or reappears, replace the PCB. |
| F05 | Anomaly in the parameters of the control board | Incorrect PCB calibration/parameter settings (or data corruption) causing fault diagnosis. Check/adjust model parameters with technical tool/menu; if not corrected or does not accept recording, defective PCB. |
| F07 | Anomaly in the parameters of the control board | Inconsistent PCB configuration with the equipment or damaged memory. Check and reprogram the manufacturer's Pxx parameters; if the error persists after reprogramming, replace the PCB. |
| A23 | Anomaly in the parameters of the control board | Incorrect internal parameters of the PCB (model/gas/curves), usually after a board change or deletion. Reprogram parameters according to the service manual; if it does not stabilize, the PCB is damaged. |
| A24 | Anomaly in the parameters of the control board | Fault/error in the main board parameterization or memory corruption. Check and re-record factory parameters; if the fault persists, replace 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.
