How do you perform an ohm test on an oil burner transformer?

To perform an ohm test on an oil burner transformer, first ensure that the power is disconnected to prevent electrical shock. Using a multimeter set to the ohm setting, connect the leads to the primary and secondary terminals of the transformer. A reading of zero to a few ohms indicates that the windings are intact; however, if the meter reads out of range or infinite resistance, there may be an open circuit in the windings. Additionally, check for short circuits by testing across the leads to ensure there is no unexpected continuity. Always refer to the manufacturer’s specifications for acceptable resistance values. Proper maintenance of oil burner transformers ensures optimal performance and longevity, making tests like the ohm test crucial for operational efficiency.
