If you do not see the part you want below, feel free to use the chat function and see if we possibly have the part you are looking for in stock.
Different Types of Ignition Transformers & How To Choose
For boilers that do not use solid-state electronic ignitors, ignition transformers are used to step up incoming voltage to ensure sufficient spark arcs across the electrodes. They typically step up to one of two voltages, depending on the specs of the boiler.
The Role an Ignition Transformer Plays in a Boiler
A boiler needs a reliable source of ignition to operate safely. If the incoming fuel is not properly ignited at startup, or during boiler firing, it can collect and create an explosion hazard.
Effects of a bad Ignition Transformer
When an ignition transformer goes bad, it will stop generating spark. This may cause excess fuel to build up, causing an explosion.
Things to consider
If you hear puffs or excessive rumbles coming from your fire side, you may have a failing transformer.
