Remeha Avanta Ignition Transformer 720481501 for Avanta Plus & Exclusive

This Remeha Avanta Ignition Transformer helps create the ignition spark sequence so your Remeha Avanta boiler can fire up reliably. If the transformer is weak or failing, you may notice ignition lockouts, repeated starting attempts, no flame, or intermittent hot water/heating.

Frequently Asked Questions (FAQ’s)

1. What is remeha ignition transformer 720481501?
An ignition transformer used to generate the high-voltage output required for reliable burner ignition on compatible Avanta models.

2. What symptoms suggest it’s faulty?
No ignition spark, ignition lockout, repeated ignition attempts, intermittent firing, or hot water/heating cutting out.

3. Is this the same as an ignition electrode?
Not exactly electrodes create the spark at the burner, while the transformer provides the high-voltage supply that enables the spark.

4. How do I confirm compatibility before ordering?
Match 720481501 plus your exact boiler model/GC No (and if possible, confirm via boiler data plate/parts diagram).

5. Does replacing it usually fix “no spark” issues?
If the fault is transformer-related, replacement restores ignition. If not, also check electrodes, leads, earthing, gas supply, and PCB control.
