I have a GE Profile Microwave, model JE1860.
All has been fine and suddenly no heating capacity. The control panel, timer, etc seem to work fine. The glass tray and rotator motor and fan motor seem fine. The light works fine.
Bad news is it will not heat a cup of water. Also notice that the sound is louder and somewhat deeper than when all was working well.
Any help would be appreciated. Any ideas on part replacement - is it the magnetron or a transformer? Do these things wear out?
Thanks,
Mark
