Deborah D Camarillo , CA October 17, 2016 Appliance: General Electric Free Standing Microwave SCA1000HWW04 Ge Microwave Sca1000hww04: The surface light under the microwave burned out. How to replace Microwave Halogen Light Bulb. I removed the cover for the light and inserted the bulb...not very exciting, however, what was impressive was the service. I ordered the bulb on a Thursday and it arrived the next day. I also ordered a motor (different time) which arrived promptly, and the instructions on their web site made it a snap to take the old one out and put the new one in.
