Question about GE Spacemaker JVM1640SJ Microwave Oven
Both ovens stopped working at different times. I recently replaced the control board and both ovens work. I noticed that neither vent fan is coming on when I run the ovens for a while. They should come on when the switch senses 210 but they never come on. The data sheet says the switches are resetable. How do I reset them or do they need replaced?

SOURCE: Buzzing noise, wont work???
The magnatron is shorting, overloading the high voltage transformer. From the picture this looks like an older unit and is probably not worth a magnatron replacement.

The power to the unit is drooping (when the heavy microwave load kicks in) causing the reset.
Try plugging it into a different outlet (whole different circuit if possible) and if that works then you have a wiring problem to the original outlet.

If some pads on the keypad are not working, then you have a failed keypad.
If you (or someone you know) might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically involved.
You can usually find helpful exploded view diagrams and order parts by entering your full model number here.
There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.
If you would like to have us do this for you, we do that for $39.95 plus part costs.
On this model, the cover will have to come off to replace the light bulb. If it's mounted in the wall, it will have to come down.
The installation instructions are nice to have in this case. You can download GE owner's manuals and installation instructions here.
I have attached a drawing to show where the bulb is on this model. It is located on the right side of the oven next to the wall of the cooking cavity.
The bulbs are available in local grocery stores, hardware stores, and stores like Wal-Mart and Lowe's.
Please feel free to contact me directly if you need more help.

You are correct the fan motor is either stuck or needs replaced.
There is no way to do this without removing the entire microwave. In case your not familiar with how microwaves work, there is a capacitor that is very large inside and can hold a charge even after it is unplugged for up to 24 hours, please take action to prevent getting shocked.
