This is usually caused by either a bad door switch (usually the top one), a loose door switch mount, or 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

If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases.

SOURCE: I would like to know

If your owner's manual doesn't cover lamp replacement, you will have to take the oven apart to do it.

If you don't have your manual, you should be able to download it from here.

I have a diagram at my site which helps you find & replace many GE cooktop and cavity light bulbs. Other models are similar. It's here.

You can find helpful exploded view diagrams and for many brands by entering your full model number here: http://tinyurl.com/gv383

A microwave can be dead for many reasons.

It may be the fuse, which is usually located on the floor of the oven behind the control panel or between the door switches.

If the 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 / body of the oven.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open.

Then when it cools, it closes the circuit and allows power through again.

When checking thermostats, if it has a hood fan thermostat, that should read open, as opposed to the others, which should read closed.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If it goes dead or blows the breaker when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

If it's intermittent or random, it may be a bad connection, usually on the control board or a loose fuse holder, or even an intermittent fuse.

You should do a continuity test on the fuse while it's in the holder (with the microwave unplugged, of course) then turn the fuse by hand or take it out and put it back in, then test it again.

If you remove the fuse, then press the meter leads against the ends, it can allow internal contact to be made and make a bad fuse appear to be good.

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

In some brands there is 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.

No lights no tripped breaker no power


There is a fuse inside of oven, do not attempt to replace it as there are high voltages remaining for a period, danger of shock. The cabinet has to come off, and you need to know what you are electrically capable of. thank you. probably fuse.

Blown fuse


Check your door switches or your turntable motor, these could also cause the fuse box to trip.

Micro blow circuit


You have a faulty interlock switch. This is one of two or three switches in every microwave that are operated by the door. The interlock switch is wired to blow the fuse if you try to run the oven with the door open. The switch may have gotten knocked out of adjustment (say by slamming the oven door) or its contacts stuck closed. If there are no other problems with the oven, a new switch should clear this up.

Fuse


The Interlock Monitor Switch is an added
safety check on the Primary and
Secondary Interlock Switches. If the
Primary and Secondary Interlock Switches
allow the oven to operate with the door
open, the Monitor Switch will blow the
fuse.

You can get more information about adjuting the interlock switch from this link

sections 7-11 thru 7-12 discuss the door interlock adjustment that will cause the 20A fuse to blow if it isn't set up right. I hope this helps you...
