Oil Furnace Transformer Test

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

Oil furnace transformer test.

Some options may also use as little as 24 volts. How to test a transformer. The most accurate is to use a voltmeter capable of measuring 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.

Transformers are an electrical component that transmit electrical energy between at least two circuits. Finally test the newly installed transformer with a voltage tester. I did one earlier but it was not installed on the oil burner. There are a number of ways to test the output voltage of the transformer.

November 11 2013 an oil furnace works by having a high voltage ignitor create a spark next to an oil nozzle. Furnaces of all types such as electric gas and oil furnaces will use transformers with 120 or 240 volts. The nozzle compresses air and oil transporting it to the spark where it is ignited to create heat. This video is part of.

With 120 volts input to the transformer the output should be approximately 10 000 volts. The ignition transformer takes 120 volts ac and transforms it into 10 000 volts ac to ignite the oil droplets. The video below can help you if you need it. Although your oil furnace burns fossil fuel it still needs electricity to light the flame.
