Extractor Fime L25R7612 Saunier Duval Themafast F 30 E H-MOD Ref. S1072500
Smoke extractor (fan) manufactured by Fime, code L25R7612, equivalent to the reference Saunier Duval S1072500. It operates at 220V and 60W. It is installed in boilers Isofast, Isomax, Isotwin, and Themafast/Themaclassic F 30-35 E. It expels combustion gases and ensures the necessary draft for ignition. It is replaced when the extractor does not start, makes noise, or the boiler locks out due to a ventilation fault.

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 boiler does not ignite and a fault related to the fan or air pressure switch appears on the screen.
Cause: The extractor does not rotate at the speed that the air pressure switch requires to allow ignition.
Check that the flue duct is not blocked and that the pressure sensing tubes to the pressure switch are properly connected; this way you can rule out issues unrelated to the fan.
- 02
The extractor starts and stops by itself during operation, without a clear pattern.
Cause: The motor intermittently loses speed due to worn bearings or a starting capacitor that is no longer functioning properly.
Turn the turbine by hand with the boiler off; if you feel any hard spots or rubbing, the bearing is worn out.
- 03
Excessive noise, louder than usual, with the extractor running.
Cause: The turbine is unbalanced due to dirt or the bearing is at the end of its useful life.
Clean the turbine and the blades of soot before discarding the part; often the noise decreases just with cleaning.
- 04
The boiler directly locks out due to a ventilation fault, without attempting to ignite.
Cause: The extractor does not start at all, due to a broken winding or a seized motor.
Check that power is reaching the extractor during a test cycle; if it is powered and does not spin, the motor is faulty.
- 05
In this modulating model (H-MOD), the boiler loses smooth ignition and jerks when starting.
Cause: This extractor adjusts its speed according to demand; if the motor does not respond well to the setpoint variations, the ignition becomes abrupt.
Compare the behavior in several ignition cycles: if it always starts with a bang, suspect the fan before the gas valve.
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.
