Oil furnace transformer test.

The video below can help you if you need it. As with igniters the transformer can be damaged by moisture and leaked oil. November 11 2013 an oil furnace works by having a high voltage ignitor create a spark next to an oil nozzle. Although your oil furnace burns fossil fuel it still needs electricity to light the flame.

Oil furnace ignitor troubleshooting posted on. 4 1 out of 5 stars 12. 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. Furnaces of all types such as electric gas and oil furnaces will use transformers with 120 or 240 volts.

Finally test the newly installed transformer with a voltage tester. As a double check an ohmmeter can be used. Heating service technicians use a special high voltage tester to check the transformer. It is standard practice for furnace technicians to carry out an output voltage test using a voltmeter.

Some options may also use as little as 24 volts. With 120 volts input to the transformer the output should be approximately 10 000 volts. The transformer converts electric voltage to create the impetus for the igniter to spark. 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.

A perhaps less common problem is ignition transformer failure. Only 9 left in stock order soon.
