Question about GE Spacemaker JVM1640SJ Microwave Oven
My microwave started sounding strange tonight, much louder than normal and apparently it isn't cooking correctly. It is only 2.5 years old so it doesn't seem like it's time for it to die. Do you have any advice?
If the sound you are talking about is a loud humming noise, this is usually caused by a component in the High Voltage Circuit going bad (Usually the Magnetron and/or HV Transformer). Depending on make and model, some of these components can cost as much as a new microwave oven. The unusual noise, associated with improper cooking results, leads me to believe you could have a bad magnetron. The transformer tends to be a bit more resilient. This is not a job that I would recommend for someone that has no electronics background, however. The HV circuit has voltage potentials of 14,000 volts or higher, and it is not recommended to take any live readings in this area due to the danger associated with the high current. I'm not trying to discourage you at all. If you have the technical "know-how" and can disassemble the unit enough to take resistance readings (no power applied) on the magnetron and/or get a part number (sometimes located a parts manual that comes with the owner's manual), it may be worth the effort to see how much a replacement part may cost. If you go to repairclinic.com, type in your make and model number, you can get a pictorial parts index with prices. Let me know if this helps you.

This answer assumes yours is a GE JVM1640, as posted.
If not, please reply back with your correct brand and model.
Most of the time, this is the magnetron, which would have a 9-year warranty.
I would advise you to contact GE Customer Service at http://www.geappliances.com/service_and_support/contact/
