PCB Saunier Duval Condens F25/F30 and Hermann Micra 25 Ref. 0010028087
The Saunier Duval Condens F25/F30 and Hermann Micra 25 PCB is the component that controls the ignition, burner modulation, pump, and safety features of the boiler. When it fails, the boiler may not start, lock out, or operate erratically, potentially displaying fault codes such as F.63, F.64, or F.67. This PCB is compatible with models from the Thema Condens, Themafast Condens, Semia Condens, and Hermann Micra ranges, among others. It is recommended to replace it if you experience these symptoms to restore the proper functioning of your boiler.

How to check if ref. 0010028087 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 0010028087. 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 0010028087 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 the display shows nothing.
Cause: A fault in the power supply to the PCB prevents the rest of the control, including the display, from receiving power.
Check that power is reaching the boiler and that the main switch is properly pressed; if everything is correct, check if there is any internal LED on the PCB lit.
- 02
The pump or the burner do not start even though the boiler is calling for heat.
Cause: The relay on the PCB does not close its contact, so the pump or the burner do not receive power even though the board is active.
Listen for the click of the relay when the demand starts; if you don't hear it, the fault is in the relay rather than in the rest of the PCB.
- 03
The fault code on the display does not match any actual gas, water, or pressure fault.
Cause: A fault in the control board can generate fault codes that do not correspond to any external component.
First, check the water pressure, the flue gas evacuation, and the gas supply; if everything is correct and the fault persists, the problem is likely with the PCB.
- 04
The boiler randomly locks out and only resets sometimes.
Cause: An unstable contact or solder joint on the PCB causes intermittent faults that do not depend on any fixed condition of the installation.
Note if the lock coincides with any specific moment (cold start, after power cut, etc.); if there is no pattern, it is more likely that the fault is internal to the PCB.
Fault codes from Saunier Duval that this spare part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F.63 | EEPROM fault. | The EEPROM memory of the main PCB is damaged/corrupted; if NTCs and wiring are correct, the cause is the PCB. Check voltages and, if it persists, reprogram/replace the PCB. |
| F.64 | Fault in the electronics / NTC. | If the NTC sensors and their wiring do not present shorts or inversion, the fault is in the PCB electronics (measurement/processing stage). Check NTCs and continuity; if okay, replace the PCB. |
| F.65 | Fault: electronics temperature. | The PCB detects overheating or its internal sensor/power stage is faulty. Check ventilation/temperature and dissipation; if everything is correct, the cause is the PCB. |
| F.67 | Fault: electronics/flame. | The flame detection/control circuit on the PCB is not plausible or defective. Check the ionisation signal and grounding; if they are correct, replace the PCB. |
| F.70 | Invalid product code (DSN). | After replacing the display and PCB without readjusting the DSN or with incorrect coding resistance, the PCB locks the equipment. Verify/adjust DSN and resistance; if not accepted, incorrect/defective PCB. |
| F.32 | Fault: fan. | When the motor and wiring are fine, the fault may be with the PCB (multiple connector on PCB, output/driver, or PWM control). Check the power/signal from the PCB to the fan; if there is no correct output, 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.
