Question about GE Spacemaker JVM1640SJ Microwave Oven
How do i check the fuse?
I am assuming that when you say everything works, that tells me that your control panel comes on and when you press the start button to heat something up the light comes on inside the microwave and the table turns and that it just does not heat. There is only one fuse inside the microwave and it is rated at 15amps. I can tell you now that it is not your fuse but your magnetron that is bad. However, you can unplug everything and take the cover off and you will see the ceramic fuse. To check it you need a continuity tester like an ohmmeter. As I said though since it is the only fuse and everything comes on it is not the fuse. The magnetron needs to be replaced then it will heat up fine and the table will turn. Replacing the magnetron can be done if you are a do it yourselfer. Once you unplug the microwave and take the cover off. The magnetron sits right behind but on top of where your control panel is. It is only held in place with three or four screws and has only three to four wires that unplug at a couple of places. Be sure to note which wires go where. Find a magnetron at either a local tv repair shop since they may have a used one that works that will fit in your microwave, or go to a local electronics supply house or get on the internet and find one there. Good luck and God bless. Let me know if there is anything I can do to help you.
