Oil Furnace Transformer Test

As with igniters the transformer can be damaged by moisture and leaked oil.

Oil furnace transformer test.

Oil furnace ignitor troubleshooting posted on. This one shows how to test the transformer spark on the gun oil burner. A 24 volt transformer is typically used as a control device to turn a higher voltage generally 120 vac into a lower working voltage for switches or relays such as in a furnace thermostat transformer. As a double check an ohmmeter can be used.

It is standard practice for furnace technicians to carry out an output voltage test using a voltmeter. The transformer converts electric voltage to create the impetus for the igniter to spark. If you are noticing bad furnace transformer symptoms such as regular blowouts run through a basic testing procedure to ensure your 24 volt. This video is part of.

The video below can help you if you need it. Some options may also use as little as 24 volts. Although your oil furnace burns fossil fuel it still needs electricity to light the flame. 1 16 of 108 results for oil burner ignition transformer oil burner ignition transformer 120v.

The transformer steps up your 120 volt house voltage to several thousand volts to produce a spark across the terminals of an igniter. Only 9 left in stock order soon. I did one earlier but it was not installed on the oil burner. Heating service technicians use a special high voltage tester to check the transformer.

Finally test the newly installed transformer with a voltage tester. There are a number of ways to test the output voltage of the transformer. The most accurate is to use a voltmeter capable of measuring 10 000 volts. A perhaps less common problem is ignition transformer failure.

November 11 2013 an oil furnace works by having a high voltage ignitor create a spark next to an oil nozzle. 4 1 out of 5 stars 12. The ignition transformer takes 120 volts ac and transforms it into 10 000 volts ac to ignite the oil droplets. 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.
