GE JES1657SMSS Repair Guide
A large 1.6 cu ft countertop microwave with sensor cooking and a stainless finish. At the top of the countertop size range, where replacement costs enough that the cheaper repairs start to make sense again.
Common problems & typical repair costs

Tech notes
At the larger countertop sizes replacement climbs toward $300, so a cheap repair — waveguide cover, turntable parts, even an interlock set — becomes worth doing again. The line stays where it always is: high-voltage components on a countertop unit are not worth paying for.
