Air Pressure Switch Boiler Ferroli - Ref. 605.99618
When you open the tap or turn on the heating, the air pressure switch of the Ferroli boiler - Ref. 605.99618 is responsible for checking the necessary air pressure for its operation. This part is crucial for the boiler to start correctly; if it fails, you will notice that the boiler does not ignite or gets locked, even though the actual pressure is adequate. It is compatible with Ferroli models such as Nef Vent CE, Innox B CE, and Era F 32 BS 60, among others. It should be replaced when you experience these symptoms or if the part shows visible damage.

How to check if the reference I39800140 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 I39800140. 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 pressure switch I39800140 resolves.
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 and remains on standby, as if it does not finish starting up.
Cause: The pressure switch acts as a safety device: if it does not detect the correct air pressure difference, it does not allow ignition.
Check that the flue outlet to the outside is not obstructed by dirt, snow, or any object, and that the intake pipe is not crushed.
- 02
The fan starts normally, but the ignition cycle does not continue.
Cause: The electrical contact of the pressure switch does not change even though the air pressure generated by the fan is correct.
Measure with a multimeter that the pressure switch changes state when the fan is running.
- 03
The startup faults are intermittent; they do not occur all the time.
Cause: An air pressure at the switching limit can cause the pressure switch to fail intermittently depending on the conditions.
Check that the intake and exhaust ducts do not have long sections, added elbows, or dirty grilles that reduce the draft.
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.
