How do you test a microwave transformer?

To test a microwave transformer, you typically begin by disconnecting it from the circuit for safety. Use a multimeter set to the resistance (ohm) setting to measure the primary and secondary windings. Check for continuity; the primary should have low resistance, indicating it’s functional. Next, inspect for shorts by measuring across the windings to ensure there’s no immediate short circuit. For further testing, if you want to evaluate performance under load conditions, utilizing a testing transformer could help determine if the transformer maintains voltage and current levels when operational. Always ensure safety precautions are followed given the potential hazards associated with microwave transformers.
