SIT 504 NAC Ignition Transformer - Boiler FE27E - code SIT 06040032-00
SIT ignition transformer, model 504 NAC (SIT internal code 06040032-00), with a primary of 230V 50/60Hz. It generates the spark that ignites the burner. The catalog sells it as a Fagor FE 24 NOX spare part, but the available data only confirms its compatibility with the FE27E boiler. It is replaced when the boiler does not ignite or the ignition fails intermittently.

How to check if ref. N55G002M7 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 N55G002M7. 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 N55G002M7 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 does not ignite the burner, although it seems to be trying to start.
Cause: The ignition transformer does not produce the necessary voltage for the spark to jump at the electrode.
Check that the electrode is clean and properly aligned with the burner before changing the transformer.
- 02
There is no spark at the ignition electrode, not even a weak one.
Cause: A fault in the primary or secondary of the transformer prevents the ignition system from having output voltage.
Check if 230V is reaching the transformer; if it is not, the issue may be with the PCB or the wiring, not with the transformer.
- 03
The ignition is intermittent: sometimes it lights up and other times it fails to ignite.
Cause: The wear of the winding causes the spark to be inconsistent instead of reliable at each start.
Check the high voltage cable and its connector: a loose connection can cause the same symptom as a faulty transformer.
- 04
The boiler locks the ignition after several failed attempts.
Cause: No spark detected, the control board cuts off the gas supply for safety after exhausting the retries.
Before replacing the part, check that the electrode does not have visible cracks in the ceramic, as a crack can cause a loss of spark just like a faulty 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.
