What are the common problems with GE microwaves?

Common problems with GE microwaves include microwave not heating, turntable not rotating, and door latch failure, which are typical for most microwave brands but occur with moderate frequency. First, not heating food though it runs is most common, due to magnetron failure after 5 to 7 years costing 50 to 100 dollars for part that generates microwaves, or high voltage diode failure at 10 to 20 dollars that converts voltage for magnetron, or high voltage capacitor failure at 15 to 30 dollars, or door interlock switch failure that prevents magnetron from energizing if door not sensed closed, all require discharging capacitor that stores lethal voltage, so technician needed. Second, turntable not turning due to turntable motor failed at 15 to 30 dollars located under bottom panel, or turntable coupler cracked that connects motor shaft to glass tray, replace both. Third, door not latching or not closing properly due to door latch hook broken at 20 to 40 dollars from slamming door, causing microwave to not start as safety interlock. Fourth, loud buzzing noise during operation due to magnetron failing. Fifth, control panel buttons not working due to membrane touchpad failure at 40 to 80 dollars from moisture and grease. Sixth, sparking inside due to food splatter on waveguide cover made of mica, clean cover with damp cloth. To prevent problems, clean interior weekly and avoid running empty.
