WAVE GUIDE

First went to Sears & got 'Security Torx' screw driver set for 8.99. Got set of 6 drivers that will fit on drill , this is what will open bottom 2 screws on rear of Microwave. The other screws on the microwave are Phillips head screws.
Then Unplug Unit put on firm surface and go to rear & side of unit & take off only screws on the perimeter of the case. Then take off screws on side of case. (only 1 side has screws) Then make sure you discharge your static electricity by touching some metal or using a grounding wire device (most of us Computer Tech's have). Then gently slide case off from under front tabs. Looking at the right side of the Microwave (front facing) you will see a plug sitting up with two screws. You will not see the bulb as it is inserted upside down in a cover which shields it. The bulb will have a 2 wire attachment shielded by a electric cable attachment. If you don't see it immediately, refer to the schematic under your case or refer to the diagram on this web site carefully. The bulb is there in plain view. After removing the two screws and re- attaching the power cable to the bulb. Re slide on the case cover and replace the screws. I kept my security Torx screws in place in case I ever need to go to a repair person for more serious service then replacing a bulb.

I forgot to place my dish in the mircowave and it ran for a few minutes, sparked and started on fire. I thought the whole mircowave was going to need to be replaced, however a repairman told me with just a part replacement, I didn't need a new microwave. I could do it myself and save a $75.00 housecall. I checked on line for the part he recommended and the parts were much cheaper through Parts Select than the GE website. It was a very simple repair. I unscrewed the old part and put in the new one. It took less than 5 minutes.
