Question about GE Spacemaker JVM1640SJ Microwave Oven
When the mircowave is on, the light is dimmer now and the food is not warm as before for the same amount of time. Once in a while, it will turn brigher for a second and then dim again. Is my magnetron going bad?
The dimming of the light indicates a big amount of current being drawn by the magnetron. can you see sparks inside the oven?..it looks like the magnetron is shorting out with the ground. what makes it short to ground could be in the wave guide cover...look for some dark spots or accumulation of carbon from old food residue which becomes carbonized due to repeated heating. carbon is a conductive material that shorts the magnetron to ground.
i hope i was able to help
