When you open the hot water tap or turn on the heating, the Honeywell Gas Valve Domina/Domitop/New Elite/Domicompact - Ref. I39804880 regulates and allows the flow of gas to the burner according to the instructions of the PCB. If this valve fails, you will notice that the boiler does not ignite, there may be flame lockouts or modulation issues. This component is compatible with several Ferroli models, such as the DOMINA F 24 E, DOMITOP F 30 E, and NEW ELITE F 24 E, among others. It is advisable to replace the valve when the mentioned symptoms occur to restore the functionality of the boiler.

How to check if ref. I39804880 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 I39804880. 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 gas valve I39804880 resolves.
The gas valve regulates and modulates the gas flow to the burner. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler does not ignite and there is no sign of a flame attempt.
Cause: The valve does not receive the command to open or does not respond, so gas does not reach the burner.
Before replacing it, check that the control board is sending power to the gas valve (look at the connector) to rule out a fault in the PCB.
- 02
The boiler locks up just when starting, almost always when it is cold.
Cause: The valve takes time to open and the control board does not detect the flame in time, locking out for safety.
If the fault occurs more frequently when cold, check the condition of the ignition electrode before replacing the gas valve.
- 03
It smells like gas near the boiler, especially right after it turns off.
Cause: The gas valve does not close properly and allows some gas to escape at the end of the cycle.
Ventilate the area and call a technician to confirm the exact source with a detector before purchasing the part.
- 04
The flame goes out on its own halfway through combustion or decreases in power without you requesting it.
Cause: The modulating part of the gas valve does not maintain a constant gas flow while operating.
Check for any gas pressure drops caused by other appliances running at the same time before blaming the gas valve.
Fault codes for Cointra that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| A01 | The burner does not ignite because there is no flame. | The gas valve does not open or does not regulate properly, so gas does not reach the burner. Check if there is power to the valve when it tries to ignite, inspect the continuity of the coils, and measure the pressure and flow at the valve outlet with a manometer. |
| A09 | Problem with the gas valve. | It could be an internal fault of the gas valve or the wiring (open coil, short circuit, or stuck valve). Check the continuity of the coils, the condition of the connectors, and whether the valve activates when receiving power. If it does not open, it needs to be replaced. |
| A16 | The gas valve is not working. | It could be a fault with the gas valve or its power supply. Check the connectors and if power is reaching the valve; if it receives the signal but does not open or regulate, the valve needs to be replaced. |
| A62 | The gas valve is not communicating with the PCB. | The valve is not receiving a signal from the PCB, which could be due to a wiring issue, damaged connectors, or a faulty valve. Check the continuity of the wiring and the voltages; if everything is fine and the problem persists, replace the valve or check the PCB. |
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.
