Product review (5 stars): OEM GE Part, MUCH cheaper than the repairman, and a super easy installation
I was quoted $775 to repair my GE Profile refrigerator, which is only about 8 years old. The compressor stopped running and we had no cold air. The repairman told me not to bother fixing it, and just replace it. While he was in my house, he mentioned the power inverter and said that they are usually the culprit, but also said the circuit board typically goes along with the inverter. After reading reviews here, I decided to go ahead and replace the inverter myself. The whole job from start to finish took me about half an hour and voila! We have a working fridge again.

Take note that the compressor may not start right up after you complete the install and plug the unit back in. It took mine 5-6 minutes before the compressor kicked on, and I was an unhappy guy for that time. But it did eventually start and is working again now.
