PCB Boiler Fagor FEB24ED3 Ref. N03A001A0
The PCB of the Fagor FEB24ED3 boiler, reference N03A001A0, controls the ignition, the modulation of the burner, the pump, and the safety features of the boiler. If it fails, the boiler will not start, will lock out, or will exhibit erratic behavior, potentially displaying the fault code F5: Control board fault. This board is compatible with several models, such as the FE-24 NOX, FEB 24 AR-1 N, and FE 26 TC-1 N, among others. It is recommended to replace it when these symptoms or the mentioned fault code occur.

How to check if ref. AS0007548 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 AS0007548. 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 AS0007548 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: One of the OMRON G5NB-1A relays on the PCB is not switching and is not sending the command to the component it should activate.
Check if you can hear the click of the relay when calling for heat; if neither of the two sounds, it points more towards the PCB.
- 02
A specific component fails to start (pump, fan, or valve) while the rest operates normally.
Cause: Each relay on the PCB controls a different component; if only one fails, the rest continue to operate.
Identify which exact component is not starting; if it's just one, check that component and its wiring first, not just the PCB.
- 03
The boiler shows an error or stops after running for a while.
Cause: The PCB is designed to operate up to 130°C; excessive heat in the junction box can cause it to fail repeatedly.
Check that the boiler casing ventilation is not obstructed and that the cooling fan, if it has one, is working.
- 04
The boiler resets itself or gives strange faults when there are other electrical appliances nearby.
Cause: The SCHAFFNER EMI filter on the PCB protects against interference; if it is damaged, external electrical noise can seep in and cause resets.
Try unplugging other devices on the same electrical line and check if the fault disappears before considering the PCB as faulty.
Fault codes for Fagor that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F5 | PCB fault (internal fault of the electronic circuit). | The main PCB (AS0007548) has an internal hardware fault or control program protections/software issue, causing the boiler's self-diagnosis to lock it. Check for the arrival of 230 V and auxiliary voltages on the board (e.g., 5 VDC), fuse/relays, and absence of shorts; if the issue persists, replace the board. |
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.
