Furnaces of all types such as electric gas and oil furnaces will use transformers with 120 or 240 volts. As with igniters the transformer can be damaged by moisture and leaked oil. The transformer steps up your 120 volt house voltage to several thousand volts to produce a spark across the terminals of an igniter.
This one shows how to test the transformer spark on the gun oil burner. It is standard practice for furnace technicians to carry out an output voltage test using a voltmeter. Furnace transformer troubleshoot sequence if there is no voltage read at the output of the transformer as read by a voltmeter and power is available on the input side the transformer has failed. With 120 volts input to the transformer the output should be approximately 10 000 volts.
The nozzle compresses air and oil transporting it to the spark where it is ignited to create heat. The transformer converts electric voltage to create the impetus for the igniter to spark. As a double check an ohmmeter can be used. The video below can help you if you need it.
