Saunier Duval Isofast Condens F35E Extractor Fan Ref. S1052000
When the heating system starts, the Saunier Duval Isofast Condens F35E extractor fan is responsible for expelling the combustion gases and creating the necessary draft for its operation. If this part fails, you will notice that the boiler does not ignite or gets locked due to a fault in the flue gas evacuation, and the fault code F.32 may appear. This fan is compatible with several models, such as the Isofast Condens F30E and the Isomax Condens F30E, among others. It should be replaced when it shows operational issues that prevent the boiler from starting.

How to check if the part S1052000 is the one 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 S1052000. 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 S1052000 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 tries to ignite but shuts off after a few seconds, without producing a flame.
Cause: The extractor does not reach the necessary revolutions for the air pressure switch to send the start signal, and the control board cuts the cycle for safety.
Before changing the fan, check that the flue pipe is not blocked by ice, bird nests, or dirt: a fan in good condition will not start if it cannot expel the smoke.
- 02
The fan does not spin or attempt to start.
Cause: The motor is blocked by soot on the shaft or has a damaged winding or start capacitor.
With the boiler turned off and unplugged, turn the turbine by hand; if it is stiff or does not turn, the motor is the main suspect.
- 03
A buzzing, whistling, or loud vibration is heard when the extractor is running.
Cause: Worn bearings or unbalanced turbine due to dirt accumulation on the blades.
Clean the turbine of dust and soot and make sure that the casing screws are tight before considering the part as faulty.
- 04
The boiler intermittently locks out: sometimes it ignites properly and other times it shows a flue fault.
Cause: The motor starts irregularly because the capacitor or the start relay is losing capacity.
Observe whether the fault occurs mainly when cold or after many hours of continuous use; this helps to differentiate a worn-out fan from a problem in the control electronics.
Fault codes from Saunier Duval that this spare part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F.32 | Fault: fan | The extractor fan (S1052000) does not spin or does not reach the expected rpm/Hall confirmation, or its connector/power supply is faulty; the electronics detect incorrect flow/spin confirmation. Check the rpm with diagnostic code d.34, inspect the fan connector and voltage, and ensure it is not blocked or there are no obstructions in the intake/exhaust. |
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.
