I have been a long time lurker but felt this post needed a quick reply... We also had the same flickering problem with our GE microwave. I contacted the number on our warranty and they set up a service call with MD Appliance Service. Microwave was found defective (diode, capacitor, etc.) and they had to order parts and a new seal. Was told it was a serious problem and was emitting microwaves. This was not a good thing. He unplugged the microwave and made me promise not to use it. Had new parts installed and it was all covered by the extended warranty! Glad I purchased that extended warranty! Don't wait for an email response - call the number on your warranty. If you don't have the warranty I would call GE and speak to a live person. I believe this is a serious problem. Good Luck!
