Biasi Fan Extractor Micon 24 E Ref. BI1336104
The Biasi Micon 24 E fan is a flue gas extractor responsible for evacuating combustion gases and generating the necessary draft for the boiler to start. When this part fails, the boiler does not ignite or locks out due to a flue gas evacuation fault, potentially displaying the fault code 05E: Fan control anomaly. It is compatible with boilers from the Manaut Micon range, such as the Micon 24 and Micon 24E, as well as models from the Manaut Minox and Biasi M90 ranges. It should be replaced when the mentioned symptoms occur.

How to check if the part number BI1336104 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 BI1336104. 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 BI1336104 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 shows a fault related to the flue or exhaust.
Cause: The extractor does not achieve the necessary flow rate for the air pressure switch to confirm the smoke evacuation, which causes the control board to block the gas.
First, check if the chimney or the flue is blocked by soot or any external element before replacing the fan.
- 02
The fan is making a noise or vibration that can be felt even from outside the boiler.
Cause: The wear of the bearing or dirt on the impeller blades creates an imbalance that is transmitted to the entire casing.
Touch the casing of the extractor with the boiler on, carefully, and check if the vibration is more intense there than in the rest of the equipment.
- 03
The extractor starts when the boiler is turned on, but it stops before the flame ignites.
Cause: This may be caused by a motor failure that does not maintain the necessary rotation speed throughout the sweeping and ignition cycle.
Check if the extractor reaches normal speed or if it runs at half power before stopping.
- 04
After the summer without use, the boiler does not start on the first attempt even though it was working well before.
Cause: The extractor shaft may have seized due to prolonged inactivity, especially if it has accumulated dust or moisture.
Try to free the shaft by carefully turning the impeller by hand before assuming that the part is faulty.
- 05
The boiler turns on but locks out after a few seconds, during the startup.
Cause: If the extractor loses revolutions right after the initial start, the air pressure switch stops detecting the extraction and cuts off the gas.
Observe if the noise or the rotation of the extractor changes just before the blockage; that moment usually indicates where the fault is.
Fault codes for Biasi that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 05E | Fan control anomaly | The fan does not start or does not develop the minimum depression, and the flue pressure switch does not switch; the PCB detects a fan control fault. Check voltage/power supply to the motor, free rotation, and pressure in Pa at the pressure switch (and obstructions in the chimney). |
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.

- There is a manufacturer reference suggested by a single external source (code GC E83-191, range M90: Parva/Riva Compact/Riva Plus); since it comes from only one source, it is not included as confirmed data, and it does not match what the catalog states.
