Ferroli PCB N E 112 Ref. 39800070
Ferroli N E 112 PCB Ref. 39800070 is a component that controls the ignition, burner modulation, and boiler pump. When it malfunctions, the boiler may fail to start, become locked, or operate erratically, which can lead to faults such as A99, A98, F50, F51, or A61. This PCB is compatible with models from the New Elite range, such as the NEF VENT E27 and NEF VENT CE, among others. It is advisable to replace it when these symptoms or related faults are detected.

How to check if the part number 39800070 is the one 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 39800070. 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 39800070 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 turn on: there is no display, no lights, and no response to the control.
Cause: The PCB does not distribute the 230V power to the internal control circuits.
Measure with a multimeter if there is power at the input of the PCB and check the fuse before replacing it.
- 02
The boiler turns off by itself halfway through a heating or domestic hot water cycle.
Cause: The PCB loses the reading from a sensor or the flame and shuts down for safety.
Check that the sensor connectors and the detection electrode are properly connected before replacing the PCB.
- 03
Clicks are heard on the PCB, but the circulation pump does not start.
Cause: The relay that activates the pump is worn out and does not close the contact.
Manually rotate the pump to check that it moves freely; if it does, the fault is in the relay on the PCB.
- 04
The fault code changes every time you reset the boiler.
Cause: It is an indication of a PCB with intermittent internal faults, which shows erratic readings.
Note each code that appears during several restarts; if they are different and unrelated, point to the PCB.
Fault codes for Ferroli that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| A99 | Generic fault: hardware or software error of the PCB. | The PCB (NE 112) shows an internal hardware/firmware fault; check power supply/grounding and perform manual calibration. If it persists, replace the board. |
| A98 | Too many software errors or error appeared after replacing the card; requires calibration. | Software/parameterisation error in the PCB after replacement or accumulation of faults; check and execute AUTO SETUP/full manual calibration. If it reappears, check/replace the control board. |
| F50 | Internal error of the DBMxx control board. | Fault in the control module integrated in the PCB; check the earth connection and power supply. If the error persists, replace the board/controller. |
| F51 | Internal error of the DBMxx control board. | Controller fault in the PCB; measure ground/power supply and, if not recovered, replace the PCB/controller. |
| A61 | PCB fault AGC01: internal error. | AGC01 controller fault on the PCB; check the earth connection and continuity. If it persists, replace the board. |
| F61 | PCB fault AGC01: internal error. | AGC01 controller fault located on the PCB; check earth/power supply and, if not resolved, replace the board. |
| A63 | Control board fault (ABM03): internal error. | The ABM03 controller of the PCB fails (firmware/CPU); check the ground and perform a reset/calibration. If it continues, replace the board. |
| F66 | Controller fault: internal error/firmware not loaded correctly. | Controller anomaly in the PCB (ABM03/041049G0); check grounding and reload/calibrate. If it reappears, replace the board. |
| A23 | PCB parameter fault. | Incorrect/corrupt PCB parameters; enter the technical menu to verify/restore parameters or recalibrate. If not corrected, reprogram or replace the PCB. |
| A24 | PCB parameter fault. | Incorrect parameterization of the PCB; verify/adjust board parameters and recalibrate. If it reappears, reprogram or replace the PCB. |
| A02 | Flame signal with burner off (electrode or PCB). | The PCB may give a false ionisation reading or generate a spurious signal; check the electrode/wiring and, if the reading is correct and the fault persists, the PCB is the cause. |
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.
