Sanyo Microwave Oven FAQs

Common questions about servicing and troubleshooting Sanyo microwave appliances.

A slight low hum is normal, but a loud, strained buzzing often indicates that the high-voltage diode is shorted or the transformer is under excessive load. You should discontinue use and have Essentechs inspect it.
