Ferroli Domicompact F24 Air Pressure Switch Honeywell Ref. C6065F1241:2
Honeywell air pressure switch, code C6065F1241:2, for Ferroli boilers of the Domicompact/Domina/Domitop/New Elite F24-F30 series. It switches at a pressure of 1.65 mbar (max. 6 mbar) and cuts off the ignition if the fan does not generate the necessary draft. Replacement requires first confirming the fault of the part through technical diagnosis, even when the boiler locks due to a draft or extraction fault.

How to check if ref. 39805631 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 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 that require diagnosis in the pressure switch 39805631
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 gets locked due to a draft or flue extraction fault.
Cause: The pressure switch must close the contact when it reaches its switching pressure. If it does not, the control board locks the unit.
Check that the pressure switch pressure ports are not blocked and that the silicone tubes are not hanging down.
- 02
The fan starts normally but the burner never ignites.
Cause: Without the pressure switch signal, the control board does not allow the gas valve to open for safety reasons.
Check that the fan does not have any rubbing noise and is not spinning slower than usual before replacing the pressure switch.
- 03
The display shows an error related to the air pressure switch.
Cause: It is the code that the control board displays when it does not detect the pressure switch contact closure within the expected time.
Check the wiring and connector of the pressure switch, as they sometimes come loose due to vibration, before replacing the part.
- 04
It has been experiencing intermittent ignition faults for some time, not always on the same day.
Cause: A contact that starts to fail due to wear may work well at times and poorly at others.
Note if the fault always occurs when cold or also when hot; it helps to distinguish the pressure switch from an extractor problem.
Ferroli fault codes that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| 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.
