Oil Furnace Transformer Test
Furnaces of all types such as electric gas and oil furnaces will use transformers with 120 or 240 volts.
Oil furnace transformer test. Transformers are an electrical component that transmit electrical energy between at least two circuits. Although your oil furnace burns fossil fuel it still needs electricity to light the flame. 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.
The video below can help you if you need it. Some options may also use as little as 24 volts. The transformer steps up your 120 volt house voltage to several thousand volts to produce a spark across the terminals of an igniter. Heating service technicians use a special high voltage tester to check the transformer.
The most accurate is to use a voltmeter capable of measuring 10 000 volts. The nozzle compresses air and oil transporting it to the spark where it is ignited to create heat. Oil furnace ignitor troubleshooting posted on. There are a number of ways to test the output voltage of the transformer.
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. How to test a transformer. November 11 2013 an oil furnace works by having a high voltage ignitor create a spark next to an oil nozzle.
