How to check if the ref. 61312612 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 61312612. 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 ignition transformer 61312612 resolves.
The ignition transformer generates the high voltage for the spark of the electrodes. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler tries to start, there is a slight smell of gas for a moment, and it stops without igniting.
Cause: There is no spark from the ignition transformer, gas is coming to the burner but it does not ignite and the boiler shuts down for safety.
First, check the electrode and its high-voltage cable: a crack there can cause the same fault even if the transformer is not faulty.
- 02
The fault code of the boiler indicates an ignition failure and repeats every time it attempts to start.
Cause: When the ignition transformer loses power, the control unit does not detect flame and displays the same warning repeatedly.
Clean the electrode of any soot residues before replacing the transformer: it is the most common cause of this warning.
- 03
After a period of not being used, the boiler is harder to start or fails several times in a row.
Cause: The accumulated moisture in an old ignition transformer reduces its ability to generate a spark until it dries out or completely fails.
Leave the boiler area ventilated and check if the fault improves after a while of being on before deciding that the part is broken.
Fault codes Chaffoteaux that this part resolves
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 70-80 | Flame not detected (ignition fault). | The ignition transformer/igniter (Ref. 61312612) does not generate a spark towards the electrodes: check for the absence of spark during the start-up attempt and ensure power/signal is reaching it; if there is voltage and no spark, replace the transformer. |
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.
