Saunier Duval Thema Condens F25/F30 PCB - Ref. 0010028087
The control PCB of the Saunier Duval Thema Condens F25/F30 manages the ignition, burner modulation, pump, and safety features of the boiler. When it fails, the boiler may not start, lock out, or exhibit erratic behavior. The associated fault codes include F.63, F.64, F.65, F.67, and F.70. This part is compatible with boilers from the Thema Condens range, such as models F25, F25 A1, and 30-A, among others. It should be replaced when these symptoms or fault codes are detected.

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 is unresponsive: it does not respond to the remote control, the buttons on the unit itself, and it does not display anything on the screen.
Cause: If the PCB fails, the unit becomes inoperable because all control logic and the power supply to other components depend on it.
Check that the boiler has mains voltage and that the internal fuse of the PCB is not blown before replacing it.
- 02
A fixed fault code appears on the display that prevents the boiler from restarting.
Cause: The PCB locks the unit for safety when it detects an abnormal reading from any sensor or actuator.
Note the exact code and first check the component corresponding to that fault before replacing the entire PCB.
- 03
The remote control or wireless thermostat stops controlling the boiler, even though it has batteries and seems to be working fine.
Cause: A fault in the PCB cuts off communication between the control and the boiler, even though the control is in good condition.
Try to operate the boiler directly from its own buttons to rule out that the fault is in the remote control before touching the PCB.
- 04
The boiler starts, heats for a few minutes, and then shuts off by itself, repeating the cycle over and over again.
Cause: The micro-cuts on the PCB, caused by the wear of solder joints due to heat, result in intermittent blockages.
Check if the cut always occurs at the same point of ignition (flame, modulation) before declaring the PCB faulty.
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.
