Oil Furnace Transformer Test

Transformers are an electrical component that transmit electrical energy between at least two circuits.

Oil furnace transformer test.

Oil furnace ignitor troubleshooting posted on. This video is part of. Furnaces of all types such as electric gas and oil furnaces will use transformers with 120 or 240 volts. Although your oil furnace burns fossil fuel it still needs electricity to light the flame.

The ignition transformer takes 120 volts ac and transforms it into 10 000 volts ac to ignite the oil droplets. Transformers regulate the voltage in circuits but in some cases these can go bad and cause a circuit to not. The transformer steps up your 120 volt house voltage to several thousand volts to produce a spark across the terminals of an igniter. With 120 volts input to the transformer the output should be approximately 10 000 volts.

Heating service technicians use a special high voltage tester to check the transformer. How to test a transformer. The most accurate is to use a voltmeter capable of measuring 10 000 volts. Some options may also use as little as 24 volts.

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. There are a number of ways to test the output voltage of the transformer. This one shows how to test the transformer spark on the gun oil burner.
