Oil Furnace Transformer Test

A perhaps less common problem is ignition transformer failure.

Oil furnace transformer test.

The ignition transformer takes 120 volts ac and transforms it into 10 000 volts ac to ignite the oil droplets. It is standard practice for furnace technicians to carry out an output voltage test using a voltmeter. 1 16 of 108 results for oil burner ignition transformer oil burner ignition transformer 120v. Although your oil furnace burns fossil fuel it still needs electricity to light the flame.

As with igniters the transformer can be damaged by moisture and leaked oil. The video below can help you if you need it. More buying choices 55 00 26 new offers allanson 2721 628g ignition transformer for beckett afg. I did one earlier but it was not installed on the oil burner.

Finally test the newly installed transformer with a voltage tester. As a double check an ohmmeter can be used. This one shows how to test the transformer spark on the gun oil burner. Heating service technicians use a special high voltage tester to check the transformer.

The nozzle compresses air and oil transporting it to the spark where it is ignited to create heat. There are a number of ways to test the output voltage of the transformer. Only 9 left in stock order soon. If you are noticing bad furnace transformer symptoms such as regular blowouts run through a basic testing procedure to ensure your 24 volt.

Furnaces of all types such as electric gas and oil furnaces will use transformers with 120 or 240 volts. November 11 2013 an oil furnace works by having a high voltage ignitor create a spark next to an oil nozzle. With 120 volts input to the transformer the output should be approximately 10 000 volts. 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.

Furnace transformer troubleshoot sequence if there is no voltage read at the output of the transformer as read by a voltmeter and power is available on the input side the transformer has failed. Some options may also use as little as 24 volts. The transformer converts electric voltage to create the impetus for the igniter to spark. This video is part of.
