How to test a transformer.
Heating service technicians use a special high voltage tester to check the transformer.

Although your oil furnace burns fossil fuel it still needs electricity to light the flame.
I did one earlier but it was not installed on the oil burner.
Oil furnace ignitor troubleshooting posted on.
The nozzle compresses air and oil transporting it to the spark where it is ignited to create heat.
With 120 volts input to the transformer the output should be approximately 10 000 volts.
The transformer steps up your 120 volt house voltage to several thousand volts to produce a spark across the terminals of an igniter.
The ignition transformer takes 120 volts ac and transforms it into 10 000 volts ac to ignite the oil droplets.
Finally test the newly installed transformer with a voltage tester.
This one shows how to test the transformer spark on the gun oil burner.
Some options may also use as little as 24 volts.
Transformers are an electrical component that transmit electrical energy between at least two circuits.
Furnaces of all types such as electric gas and oil furnaces will use transformers with 120 or 240 volts.
Transformers regulate the voltage in circuits but in some cases these can go bad and cause a circuit to not.
