Question about GE Spacemaker JVM1640SJ Microwave Oven
The fan works and the clock works everything does except when i put something into it and try to heat it it all turns off and wants me to reset clock etc. Had a problem before and the guy replaced a fuse or something in back but do not know where it is so we can replace it.
This may have already been dealt with, but others can benefit from an accurate, thoughtful reply to this problem.
This is due to a defective or loose magnetron causing electrical interference and disruption in the control circuit board.
If your magnetron was recently replaced, it may have loose mounting nuts or bolts or the wire mesh RF gasket was not installed or got pinched.
It may also need a new high-voltage diode and stirrer, and the cavity may be affected.
GE had a campaign (but not a recall, mind you!) covering several models.
Details are in their bulletin at http://188.8.131.52/mwd/ge_mw_mag_kit_bulletin.pdf
The parts kit (that GE used to pay for) is part # WB27X10489 and is shown in the photo below.

If the fuse was bad then you would have no display and nothing would come on. Sounds like your problem is in the control board an once you see the price of a new board you should just replace the microwave.
