A few months back, I turned on the lights under the microwave and the bulbs flashed and burnt out. The next time I went to use the microwave, there is a hum, and the food appears to cook, but the "exhaust" is not working.
The fan under the microwave works, and I have not replaced the bulbs yet.
I want to avoid GE at all costs and am hoping there is an easy or at least less costly fix.

Re: GE XL1800 Microwave Problem
First of all, unplug the oven when changing the bulbs, and use good quality bulbs form a home center, as opposed to dollar store or grocery store subs.
We see (and repair) this a lot. The problem is on the control panel, which we regularly repair nationwide by mail for $39.95 postpaid.
This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.
This can often also affect the exhaust fan operation, too. The lights and fan can be inoperable or stuck on too.

You know how when you turn on a regular light bulb and it burns out with a bright flash? What happens is that when the filament burns out, it breaks and bounces back and hits the other electrical post and basically shorts out causing that bright flash. Sometimes, when the light bulb in the microwave burned out, it shorted out, and caused the circuit-board trace to burn up. (This is not just conjecture; I've seen it.) If that's the case, then you would have to replace the main control circuit board. Unfortunately, a rather expensive repair for no lights. (Although the circuit board trace can usually be repaired by direct-soldering a wire to replace the burned trace. Sears repairmen won't do this, but an independent electronic technician could do it.
please undo the all thing you have done (remove bulb).........etc.
unplug ignition transformer's primary side from its connecting pin.one pin is enough.
then power on see what happening the bord must have power in this situation because it does not drive the magnitron this time .
if no result .something wrong with cct board.
please let us know the after checking to go next level.
Mine burned out within a month. Probably due to the poor design of the machine which forces you to slam the door to get it to shut.
My biggest concern is the under counter lightbulbs it has burned out in my kitchen over the last year. I wonder how much leaking this thing really gives off. Moving in a few weeks and will be throwing this cancer machine out.
I have ran into a few of these that shorted out the control board when the light bulb burnt out. Depending on how far you want to go, you can take out the board and look for a burnt spot and possibly repair the board. Or purchase a new board, which may be more than what you want to put into the microwave.

The part that controls that is goes through your control panel on your microwave. For the lights to come on to start with the door being closed switches have to be working right and when you press start the lights come one. When the microwave is through cooking and you open then close the door then the lights should go out. The logic IC on the control panel board that detects all these events is not being reset correctly. Unless you get a microwave tech to track down the component on the control panel circuit board it is not something that you could do on your own since it takes voltage and signal checks with the proper equipment and then some soldering and desoldering of the defective component(s). Good luck and God bless.
I had the same problem. My Magic Chef, MCO153UBF Microwave had similar problems. The Magnatron, Cooling fan, Turn table and under hood lights were not working at all after hearing a pop sound under the control panel. Thought it was the fuse but the fuse was fine after testing and replacing. I checked the circuit breaker wired to my house and saw it had a break to my kitchen outlets so i flipped the switch to get back the kitchen outlets. Then I checked the microwaves Control Panel ( Printed Circuit Board) underneath and saw to traces were burnt. I soldered the two trace lines and the fixed the problem.
