-★ 1. The load end of the high-voltage transformer of microwave oven adopts "connector", which is convenient to disconnect the load.
-★ 2. First disconnect the filament connector of the magnetron to determine the quality of the magnetron. If the insurance is still burning, check the next step.
-★ 3. The remaining loads are high-voltage voltage doubling capacitors and diodes. If the fuse is still blown, it is a transformer problem, otherwise the capacitor or diode is damaged.
Please look at the load diagram of the microwave oven high voltage transformer:
