Fagor FEE 20 2 B Smoke Extractor Fan Ref. MU1018800. This fan is responsible for evacuating combustion gases and creating the necessary draft for the boiler to start. When it fails, the boiler does not ignite and may lock out, displaying the fault code F2: The air pressure switch does not detect air circulation during ignition. It is compatible with models such as FE 20 E-2 N, FE 20 E-2 B, and FEE 20-2 B, among others. It should be replaced when problems are detected in ignition or smoke evacuation.

How to check if ref. MU1018800 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 MU1018800. 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 MU1018800 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 stops immediately, without lighting the flame.
Cause: The extractor does not reach the necessary revolutions for the air pressure switch to allow the gas to pass, and the control board cuts the cycle for safety.
Check if the impeller starts abruptly or takes time to reach speed; if it takes time, the problem may be with the extractor rather than the gas valve.
- 02
A strange noise can be heard, like a buzzing or rubbing sound, especially when starting the burner.
Cause: The impeller may be unbalanced or the bearing may be worn, causing friction with the turbine housing.
Listen to see if the noise stops immediately when you turn off the boiler or if it gradually fades away: if it takes time to stop, the problem points to the extractor.
- 03
The boiler is locking out and displaying a fault related to the fan or flue.
Cause: If the extractor does not move enough air, the system that controls the smoke evacuation does not validate the cycle and cuts off the ignition.
Before replacing the part, check that the flue gas outlet is not blocked by soot, snow, or any other obstruction at the external terminal.
- 04
The extractor does not move, it remains completely still.
Cause: The motor may have lost electrical connection or have damaged windings, preventing the rotation that activates the ignition sequence.
With the boiler without gas supply, check if the impeller turns smoothly by hand or if it is stuck.
Fault codes for Fagor that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F2 | The air pressure switch does not detect air circulation during ignition and the boiler locks out. | If the flue extractor (fan) does not start, spins without flow, or is faulty, the depression is not generated and the pressure switch does not switch; check 230 V~ at the fan connector and its spin/flow, and check the pressure switch (COM–NO) during start-up. |
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.
