How to check if ref. 39841320 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 39841320. 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 gas valve 39841320
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 the burner is not receiving gas.
Cause: The gas valve does not open correctly even though the control board sends the ignition signal.
Check that the valve receives 24VDC power at the moment of ignition before replacing it.
- 02
The ignition is intermittent: sometimes it lights up and other times the flame goes out a few seconds after starting.
Cause: One of the internal seals of the gas valve does not open or close consistently, and the system shuts down for safety.
Repeat several consecutive ignition attempts and note whether the fault is always the same or varies; this helps to distinguish between the flame electrode valve.
- 03
There is a smell of gas near the gas valve, especially when the boiler is off.
Cause: The internal sealing of the gas valve has failed and allows gas to pass through even when it is closed.
Apply soapy water to the threaded connections before confirming the leak, as sometimes it's a joint and not the valve.
- 04
The flame is weak or sooty even though the boiler is working.
Cause: The outlet pressure regulator of the gas valve does not maintain the working pressure within the correct range.
If you have a pressure take-off, measure the outlet pressure before replacing the complete gas valve.
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.
