Saunier Duval Master Twin L85E Extractor Ref. 05603600
When the heating starts, the Saunier Duval Master Twin L85E Extractor is responsible for evacuating the combustion gases and creating the necessary draft for the boiler to operate correctly. If this part fails, you will notice that the boiler does not ignite or gets locked, and fault codes F.32 or F.33 may appear. This extractor is compatible with models such as Master Twin L85E, Twin F28E, Thelia 30E, and Thelia Twin 28E, among others. It should be replaced when you experience ignition or locking issues with the boiler.

How to check if the ref. 05603600 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 05603600. 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 05603600 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, stops, and gets locked almost immediately.
Cause: The extractor does not reach the necessary speed and the air pressure switch does not detect the flow in time.
Check if the impeller starts normally when receiving power, or if you notice a moment of hesitation before it spins: that delay indicates a problem with the extractor.
- 02
There is a noise of rolling or vibration that wasn't there before, especially when starting up.
Cause: The wear of the motor bearing causes friction and imbalance in the rotation of the impeller.
With the boiler turned off, turn the shaft by hand: if you feel roughness or play, the bearing is worn out.
- 03
The extractor does not start at all, the boiler remains idle as soon as heat is requested.
Cause: There may be an internal fault in the motor that prevents it from turning even though it receives power.
Check with a multimeter if power is reaching the fan before replacing it: rule out a wiring or PCB issue.
- 04
The boiler repeatedly locks out with an air pressure switch fault, although sometimes it works fine.
Cause: The extractor does not always reach the same rotational speed, typical of a motor that is starting to fail intermittently.
Note if the fault occurs more in cold conditions or after several hours of use: this helps to distinguish a failing extractor from a specific blockage.
Fault codes from Saunier Duval that this spare part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F.32 | Fault: fan | The extractor (fan) gets blocked/faulty or its tachometer/Hall signal is invalid, causing the rpm to go out of tolerance and the boiler goes into lockout; check the motor power supply and connectors, and verify rotation/consumption or rpm from diagnostics. |
| F.33 | Air pressure switch fault | The extractor does not generate the required depression/flow and the pressure switch does not close, causing the fault; check the fan start-up and flow, measure the pressure switch closure at the start, and inspect the ducts/Venturi. |
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.
