PCB Saunier Duval Themafast Condens F30 A H ES Ref. 0010028087
The Saunier Duval Themafast Condens F30 A H ES PCB (control board) Ref. 0010028087 is the component that controls the ignition, burner modulation, pump, and safety features of the boiler. When it malfunctions, the boiler may fail to start, become locked, or operate erratically. Users may notice symptoms such as the inability to ignite the boiler or unusual behavior in its operation. This board is compatible with several models from the Thema Condens, Themafast Condens, and Semia Condens ranges, among others. It is recommended to replace it when fault codes F.63, F.64, F.65, F.67, or F.70 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 completely off, with no signs of life on the display or indicators.
Cause: The PCB distributes power to the rest of the electronics; if it fails, the entire system is out of service.
Check that power is reaching the boiler and that no fuse or circuit breaker has tripped before declaring the PCB faulty.
- 02
The boiler requests heat, but the pump, the fan, or the gas valve do not activate.
Cause: The PCB has a relay that gives the final command to those components; if it gets stuck or burns out, the control signal is not executed.
With a multimeter, measure if there is current at the output of the affected component when the boiler demands heat, before replacing the PCB.
- 03
An error code appears on the display that repeats frequently, even after the boiler is reset.
Cause: The control electronics detect something out of range in a sensor or actuator and lock the equipment to protect it.
Note the code and check the component it refers to (sensor, pressure switch, flame sensor) before replacing the PCB.
- 04
The boiler suddenly stops during operation and then restarts without anything being touched.
Cause: Intermittent contact faults on the PCB, typical with repeated heating and cooling, cause these momentary cuts.
Check if the cut always occurs at the same moment in the ignition cycle before assuming it is 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.
