Saunier Duval Isofast F30 H MOD Fime Extractor Fan Ref. S1072500
If your boiler does not ignite or gets blocked due to a flue gas evacuation fault, you may need the Saunier Duval Isofast F30 H Extractor Fan, Ref. S1072500. This flue fan evacuates combustion gases and creates the necessary draft for the boiler to start. When it fails, you may receive fault codes such as F2, 02, or 10. It is compatible with models such as Themafast F 30 E, Isofast F 30 E H-MOD, and Isotwin F 30 H-MOD, among others. It should be replaced when it malfunctions, preventing proper flue gas evacuation.

How to check if ref. S1072500 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 S1072500. 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 extractor S1072500 resolves.
The extractor evacuates the combustion gases with forced draft. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The extractor does not start and the boiler does not ignite at all.
Cause: The extractor motor may be damaged, preventing the PCB from initiating the ignition.
Measure with a multimeter if current is reaching the connector of the fan; if it is and it doesn't spin, the motor is faulty.
- 02
A strange noise is heard when turning it on, different from the usual one.
Cause: The wear of the bearings or the accumulation of dust in the turbine prevents the proper rotation of the blades.
Clean the turbine of soot or dust before replacing the part; sometimes, that is enough.
- 03
The boiler locks out with a fault warning from the fan when trying to ignite.
Cause: If the extractor does not reach the correct speed, the PCB cuts off the ignition for safety.
Check that the flue pipe is not blocked by nests, ice, or dirt before considering the part as broken.
- 04
The boiler does not ignite and the fan shows no movement.
Cause: A fan that does not start indicates a possible burnt motor or a seized shaft.
With the boiler turned off, try to turn the turbine by hand; if it doesn't move, the problem is with the motor.
Fault codes from Saunier Duval that this spare part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F2 | Air deficiency safety (airflow/air intake fault). | The faulty, blocked, or unpowered extractor (fan) does not generate the necessary depression, the pressure switch does not switch, and the boiler enters F2; check voltage to the motor, free rotation/noise, and switching of the air pressure switch. |
| 02 | Airflow safety (extraction/aspiration fault) in ISOFAST ranges F. | Extractor fault prevents correct airflow/smoke flow and activates safety 02; check power supply to the fan, ensure it rotates without friction, check the condition of pressure tubes and pressure switch, and ensure the duct is not obstructed. |
| 10 | Fan fault in ISOFAST ranges F. | Fault in the extractor (motor/wiring/tachometer) detected by the electronics; check power supply and signal return, motor continuity, and ensure the fan is not blocked. |
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.
