Not sure what you mean by a board sensor, but you can do a Yahoo search for my text file "doorsw.txt" which will give you important safety tips and help you find, diagnose and replace the door switches. You can find exploded view diagrams of this oven at On that page, select "repair part" under step one. Under step two, selct "Microwave" from the drop-down menu. Then when you click "GO" a pop-window will come up for you to enter your model number and it will lead to the parts lists and diagrams. But as detailed in my file "doorsw.txt" you can find generic switches locally at applaince parts stores in your area.

Why does my ge spacemaker jvm1740dd1cc no longer heats and the turntable does not work?

Bad door switch. Look for burnt terminals on one of the door switches. Replace the switch and cut off the burnt terminals and splice on new ones.

GE Spacemaker 1400 acts like everything works but does not heat.

Hello :

This happens because of a bad door switch . The plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door .

Check also the turntable . It could be out of it's right place .


1:Don't slam your microwave door because this may cause the fuse to blow and this is the reason of bad door switch problem .
2: A microwave is capable of giving you a serious electrical shock even when it's unplugged , so I recommend you to call a repair technician for help .

please don't forget to rate .

good luck

Condensation inbetween glass door on GE Spacemaker

Your glass seal has failed and I doubt it makes sense to replace the door. Yes, it can be dangerous as the moisture becomes worse you risk the chance the glass could over-heat and blow out. Sounds like you need to replace it, sorry!

Microwave oven stays on continuously and won't heat food.

Spacemakers have had problems with there magnatron, part is around 170.00. Depending on the year it is covered under a warranty however the labor is not. I have replaced 3 spacesavers for people already due to this issue. Unit runs but will not heat.

GE SpaceMaker Microwave suddenly stops while heating

I had same problem last week. My GE JVM1650 Spacemaker stopped after a few seconds of heating. Owned 16 months, manufactured Jan 2005. It was the magnetron, which was replaced yesterday. The magnetron has a 10-year warranty, but I had to pay $161.00 for labor by a GE technician. The call-out fee was waived at my request. I don't know what that amount would have been, but I can't believe the $161.00 for what was about 1/2 hour labor once diagnosed. Good Luck!
