Question

Explain the procedure of testing a high voltage capacitor of microwave oven.

Hint:

Always discharge high voltage capacitors before testing to prevent electrical hazards.

Answer 1

Procedure for testing a high voltage capacitor:
1. Ensure the microwave is unplugged from the power outlet.
2. Safely discharge the capacitor with an insulated screwdriver to prevent electrical shock.
3. Detach the capacitor and examine it for any visible damage.
4. Employ a multimeter set to resistance measurement to assess continuity.
5. Interpret the meter reading: a functional capacitor will display a rising resistance, whereas a faulty one will show either zero or infinite resistance.
