Yes we were not communicating on the same page I was thinking step down transformer and yes there are step up transformers as well but in the case of stepping up to an igniter I alway referred to this as the igniter package just different terminology same meaning in the different areas of the country. No it should not be humming loudly I would recommend having it checked. As mike stated better safe than sorry. As an after thought I probally would not really consider what you are calling a transformer a true transformer as this ignitor does not use AC voltage as the ignition point I would want to call it a converter just my thoughts.

Thanks Charley. I call it a transformer because that is what they call it on the service receipt and when i look it up online, I see them known as Allason Transformers that step up from 110V to 10000V.

Stephen I am just picking at you 110-volts to 10000-volts if this was Alternating current (AC) I think maybe it would blow up the furnace and your home. Lets try stepping up from 110 volts A/C to 10000 volts DC which is converted to DC by your igniter package or transformer if you perfer. Good Luck. Stay safe.

Charley the step up transformer for the oil burner ignitor is 10,000 VAC and no it won't blow up in the furnace. No DC units that I am aware of.

Well I told you I was not the sharpest pencil in the box on oil furnaces just can not imagine not being DC have to go back to the books Thanks
