How to check if ref. 39805631 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 39805631. 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 39805631 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 emits a beep or flashes a fault code before igniting and does not produce a spark.
Cause: The air pressure switch does not close the circuit because it does not detect the minimum depression of the extractor.
Before changing it, check that the fan starts correctly, without noises or rubbing.
- 02
The boiler turns off by itself a few seconds after starting, especially with long flue pipes or with many bends.
Cause: In long runs, the pressure drop can cause the pressure switch to be right at the limit of its switching point.
Make sure that the diameter and length of the flue pipe match the specifications of the boiler.
- 03
The boiler fails intermittently, sometimes it ignites and sometimes it does not.
Cause: A partially blocked pressure intake tube causes the pressure switch to switch erratically.
Inspect the pressure connections and the silicone tube fittings for condensation or dirt.
- 04
The boiler has been exposed to water and since then it shows a fault in the pressure switch.
Cause: Moisture on the internal contacts prevents the pressure switch from closing the circuit, even though the air pressure is correct.
Visually check for signs of moisture, rust, or scale around the pressure switch before replacing it.
Fault codes for Ferroli that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F4 | Operation of the air pressure switch. | The air pressure switch remains closed when it should open (stuck contact or tubes/venturi improperly connected/blocked). Check with a multimeter that it opens when the fan stops and inspect pressure tubes and air/smoke ducts. |
| F5 | Operation of the air pressure switch. | The pressure switch does not close within the time (~55 s) after activating the fan due to lack of depression/draught or a defective pressure switch. Check closure with a multimeter when starting the fan and inspect the venturi, pressure tubes, and possible obstruction in air/smoke. |
| F6 | Operation of the air pressure switch. | The pressure switch contact remains closed after several start-up attempts, indicating a stuck APS or reversed connection. Measure opening/closing with a multimeter and check the correct connection of the tubes to the pressure switch and the operation of the fan. |
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.
