Honeywell Flue Pressure Switch for Biasi Micon 24 E - Ref. BI1036102
Differential pressure switch for flue gases that controls the proper evacuation of combustion gases before allowing the burner to ignite. If it does not detect the correct pressure in the flue pipe, it blocks the boiler for safety reasons. The replacement requires first confirming the fault of the part through technical diagnosis, even when the boiler does not start due to draft failure or the pressure switch does not close the contact despite the extraction working.

How to check if ref. BI1036102 is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Find the reference printed on the installed part and check whether it matches the catalogue reference BI1036102. 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 that require diagnosis in the pressure switch BI1036102
The pressure switch controls the air or water pressure to authorize operation. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler does not ignite, but the flue fan seems to be working well.
Cause: The flue pressure switch measures the pressure before and after the burner; if it does not detect the correct difference, it prevents ignition even if the extractor is functioning.
Check that the flue duct is not obstructed (blocked terminal, accumulated condensation) before considering that the pressure switch is faulty.
- 02
The blockage is intermittent: some days the boiler starts without issues and other days it stops when starting.
Cause: A smoke pressure switch with a damaged diaphragm can change state irregularly in response to small variations in draft.
Check that the pressure take-off pipes are not condensating or bent; this is common in the flue side take-offs.
- 03
The flue and extraction have been checked and are functioning correctly, but the boiler keeps locking out.
Cause: If the duct and the extractor are in good condition, it is possible that the pressure switch does not close the contact even if there is sufficient pressure.
Check with a multimeter that the contact closes with the extractor running before replacing the part.
- 04
The boiler has been experiencing sporadic lockouts that are resolved by resetting.
Cause: This is the typical behavior of a pressure switch that is at the limit of its adjustment, which changes state in an unstable manner before failing completely.
Keep a record of when the fault occurs (cold, wind, after a reset) to confirm the pattern before replacing the part.
Fault codes Biasi that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| E05 | Flue pressure switch anomaly | A problem has been detected in the gas evacuation. This can be dangerous and requires immediate attention. If you see this code, the flue pressure switch may be failing and needs to be replaced. It must be confirmed through diagnosis; the code alone does not justify changing the spare part. |
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.
