Nordgas Ignition Transformer AC04ABK1LG FE-24 NOx/1N Ref. MUR000064
Ignition transformer Nordgas AC04ABK1LG FE-24 NOX/1N Ref. MUR000064. This transformer is responsible for generating the spark needed to ignite the burner of the boiler. If it fails, you will notice that the boiler attempts to start without achieving a flame, which can lead to a lockout, indicated by the fault code E01: Ionization lockout. This component is compatible with several boilers, including the FE 25 NOX/1 N model from Fagor, among others. A technician must confirm through diagnosis whether it needs to be replaced upon detecting ignition problems or recurring lockouts.

How to check if ref. MUR000064 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 MUR000064. If it is not visible, do not identify the part by 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 ignition transformer MUR000064
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 even though gas is reaching the burner.
Cause: If there is gas but no spark to ignite it, the problem may lie in the ignition system and the transformer that powers it.
Confirm that there is a smell of gas for a moment when attempting to start; if so, the problem is more likely related to the ignition than to the gas supply.
- 02
The ignition is intermittent: sometimes it lights on the first attempt and other times it takes several tries.
Cause: A transformer with aged insulation can generate an irregular arc that only sporadically ignites the gas.
Test several consecutive starts with the cold boiler; if the behavior is erratic for no apparent reason, suspect the transformer.
- 03
The boiler locks out due to an ignition fault and needs to be reset manually.
Cause: Without a reliable spark, the control board does not confirm the flame within the safety time and locks the unit.
Before changing the transformer, check that the electrode and the high voltage cable do not have cracks or dirt.
- 04
The ignition fault did not appear suddenly, but rather worsened gradually, requiring more attempts each time.
Cause: The windings of transformers degrade with use and heat, generating increasingly weaker arcs before failing completely.
If the problem has been worsening gradually instead of appearing suddenly, it is consistent with the natural wear of the transformer rather than a specific gas failure.
Fagor fault codes that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| E01 | Ionization block | If the ignition transformer does not deliver high voltage to the spark plug, there is no spark and the PCB does not detect a flame through ionisation, causing the unit to lock out. Check for the absence of spark during start-up and measure the output of the transformer/ignition cable during the ignition attempt. |
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.
