Question about GE Spacemaker JVM1640SJ Microwave Oven
I have a spavemaker 1800 mocowave ,There is current going into it , but nothing lights up , the light , temp controls amd memeoy pad . Can you tell me what might be the problem
Itmay be the fuse, which is usually located behind the grille or on thefloor of the oven behind the control panel or between the door switches.
Atour site, we now have a video available showing how to remove a typicalover the range control panel assembly in under 5 minutes.
Ifthe fuse is good, it may be an open thermostat or thermal cutout (TCO)/ thermal fuse on or near the magnetron or on top of the cavity / bodyof the oven.
You can usually find helpful exploded view diagrams and order parts by entering your full model number here.
Thereshould also be a "mini-manual" hidden inside the unit behind thecontrol panel or hidden on the left side behind the grille, which isvery helpful when troubleshooting & testing.
It will tell you how to test various components, too.

It sounds like the magnetron may have
either failed or is not being supplied with the extremely high
voltage required to run it.
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 on high resistance range for short circuit, the capacitor can fail and go short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.
