Microwave not heating or making loud buzzing noise? The high voltage diode regulates power to the magnetron. DIY repair typically takes 30-45 minutes.
LG Help-line said probably a failed magnetron, but since out of warranty,referred me to an authorized LG repair service. They wanted $79.95 service call to come out & diagnose problem. I ordered replacement magnetron for less than cost of a service call, Plus the part was delivered next day! Works like new again. Happy wife = happy life! Notes for DYI-ers: 1.Be careful removing over the stove microwaves--get help,they are heavier than you think. 2.Unplug microwave for 48 hrs, carefully... Read more
Microwave won't heat or makes loud buzzing noise? The diode regulates magnetron current flow. Simple repair—test with multimeter for continuity.
I have a multimeter so I was able to check the fuse per website recommendations and it was blown.

Turntable stopped turning or making noise? This microwave motor rotates the glass tray for even heating. Easy DIY fix with basic tools in under an hour.
I googled the make and model, and found the part on AppliancePartsPros.com. The underside of the oven has a metal grille with numerous openings of various shapes and sizes. There is a rectangle that is punched into this grille, just below the motor. I pried between the vent holes to snap the connections near the perimeter on the punched rectangle. I only did this on three sides. Then pry up the rectangle away from the connected side. Undid the hold down screw, separated the motor from the... Read more
