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 ignites, the fan runs, and it shuts off before the flame appears.
Cause: The air pressure switch checks that there is sufficient draft before opening the gas valve; if it does not close, it does not ignite.
First, check that the extractor is working at a good speed and without any strange noises.
- 02
It gives a flue gas evacuation fault and the external duct is clean and clear.
Cause: The fault may be in the pressure switch itself or in its tubes, not just in the outlet duct.
Check the complete path of the silicone tubes of the pressure switch, including the fittings, looking for cracks or disconnections.
- 03
The boiler is old and has been failing more often when starting in cold conditions, especially in winter.
Cause: Over time, the diaphragm of the pressure switch loses elasticity and has more difficulty reaching its switching point.
Note if the fault is more frequent with the boiler cold, as this indicates a possible problem with the pressure switch before replacing other parts.
- 04
A recent maintenance has been performed and since then it shows an air fault.
Cause: If the pressure switch tube has been moved or pinched while handling the boiler, it will stop receiving the pressure signal correctly.
Check that no pipe has been crushed or disconnected after the last maintenance.
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.
