How do you test an oil burner transformer?

To test an oil burner transformer, first ensure that the power is disconnected for safety. Use a multimeter to check the primary voltage of the transformer by measuring the incoming voltage at the primary terminals; it should match the specifications indicated on the transformer label. Next, test the secondary voltage by measuring across the secondary terminals; it should also align with the expected output voltage. Additionally, inspect for any physical signs of damage such as burned wires or corrosion. Finally, verify continuity through the transformer windings ensuring there are no open circuits present. By following these steps, you can effectively assess the functionality of the oil burner transformer and identify any issues that may require your attention.
