The transformer steps up your 120 volt house voltage to several thousand volts to produce a spark across the terminals of an igniter.
Oil furnace transformer test.
Transformers are an electrical component that transmit electrical energy between at least two circuits.
The nozzle compresses air and oil transporting it to the spark where it is ignited to create heat.
November 11 2013 an oil furnace works by having a high voltage ignitor create a spark next to an oil nozzle.
The ignition transformer takes 120 volts ac and transforms it into 10 000 volts ac to ignite the oil droplets.
With 120 volts input to the transformer the output should be approximately 10 000 volts.
This video is part of.
There are a number of ways to test the output voltage of the transformer.
Although your oil furnace burns fossil fuel it still needs electricity to light the flame.
How to test a transformer.
I did one earlier but it was not installed on the oil burner.
Finally test the newly installed transformer with a voltage tester.
Oil furnace ignitor troubleshooting posted on.
This one shows how to test the transformer spark on the gun oil burner.
Heating service technicians use a special high voltage tester to check the transformer.
The video below can help you if you need it.
Some options may also use as little as 24 volts.
