Question about GE JES1288SH Convection/Microwave Oven
The units cooling fan runs whenever cooking. Today it started normally then the cooling fan stopped running, but the oven kept cooking. How do I verify whether fan is bad or something more serious.
The rectifier diode could indeed be bad. But first I would want to know what value (in uF) the old one was and what is the value of the new one? If they're too far off, the difference in the capacitive reactance could throw off the "tuning" of the circuit. The uF value of the capacitor is optimized in relation to the other components used in the system. Of course, you'd also want to be sure your new cap is at or slightly above the working voltage rating of the old one, too.

If it were just just not cooking, I would suspect the magentron. But since the fan is also not working, I think you have a bad door switch. If you or a friend decide to work on it, we have *critical* safety and disassembly info at our site, as well as other specific troubleshooting information and help. In my professional opinion, no one should work on a microwave unless they are fully informed and aware of the deadly hazards and necessary precautions. You can find safety and disassembly text files (as well as a text file which helps in diagnosing and repairing door switch problems) at http://www.microwavedisplay.com You can find helpful exploded view diagrams and order parts by entering your full model number here: http://tinyurl.com/gv383

SOURCE: GE SPACEMAKER OVEN DOES NOT COOK
I have a JVM1430 microwave, it has a 9 yr warrantee on the magetron, I called customer relations 800 386 1215 and they sent a new magnetron at no charge. Now it all works

Thought I had answered this, but this is usually caused by either a bad door switch, a loose door switch mount, or possibly a problem on the control panel.
Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.
Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.
If you someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

There should also be a "mini-manual" hidden inside the unit behind the control panel, which is very helpful when troubleshooting.
If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases.
We're happy to help and we appreciate your thoughtful rating of our answer.

yes, at the back of the microwave there are 4 or 6 screws, take them out and then pull the cover follow the cable( the one you connect to the outlet) going to the inside of the microwave inside you will see the fuse change it with the same size, it is a slow burn fuse
