Question about GE Microwave Ovens
My GE model JVM1540SN1SS microwave has just recently started working only intermittently. Everything always appears to be working (lights, fan, touchpad) but you never know if it is working until you open the door and check the food. If it has not heated it may take several attempts to get the oven to heat. When it does heat it works perfectly. What might be the problem and can it be repaired?
Check the circuit board for stressed solder joints. Some resoldering may do the job.

Does the turntable rotate? If everything but this works (except no heat), you probably have a bad door switch. Here's a discussion of what's involved in replacing it: http://www.fixya.com/support/t267796-kenmore_microwave_hood_combination_over
If the turntable does rotate, I'd suspect a more significant failure, such as the transformer, capacitor, or magnetron. If it's any of these, it's time to replace the unit.

SOURCE: Microwave won't heat food.
My Whirlpool microwave, over the stove, stopped working when my son used it to heat his food and a heavy sound came out, like something exploded in it. When I check it, there was nothing broke. Everything works fine except that it does not heat. I will appreciate any help

That would be 'the primary interlock (top door switch), or its mount may be loose or cracked.
It may be a coincidence, or not. Hard to say.
Door switch or mount trouble is usually caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.
But it could be misalignment from the door work. Too bad he didn't just replace the door handle. That's such an easy job.
There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.
The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.
Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.
It's usually more economical and safer to add a dab or two of hot glue to the mount to secure the switch. Let it cool for about 30 minutes before using.
One test that sometimes helps is to gently lift up (and/or push down) on the door or handle as you try to start it. If it works or tries to work, then it's a door switch mount or door alignment issue.

this is something you should probably call a repair technician for, due to the danger of the componentry.
Usually in ther case of this problem, even a technician will advise you to replace the unit, in the minds of cost effectiveness and safety...
