Oil Furnace Transformer Test

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.

The most accurate is to use a voltmeter capable of measuring 10 000 volts. I did one earlier but it was not installed on the oil burner. With 120 volts input to the transformer the output should be approximately 10 000 volts. Transformers regulate the voltage in circuits but in some cases these can go bad and cause a circuit to not.

This one shows how to test the transformer spark on the gun oil burner. Oil furnace ignitor troubleshooting posted on. November 11 2013 an oil furnace works by having a high voltage ignitor create a spark next to an oil nozzle. How to test a transformer.

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. Although your oil furnace burns fossil fuel it still needs electricity to light the flame. Finally test the newly installed transformer with a voltage tester.

Heating service technicians use a special high voltage tester to check the transformer. There are a number of ways to test the output voltage of the transformer. Transformers are an electrical component that transmit electrical energy between at least two circuits. The video below can help you if you need it.
