Our GE refrigerator is only four years old, and it is now on its 3rd motherboard. It is covered under warranty but for the parts only, not the labor - which can only be done by a GE technician.
Even better, plan to wait about two weeks to get it working again after you call them.
I spoke with GE customer service, and they did not seem to understand why it was a problem that the same part has been replaced 2X in 4 years - apparently, they consider that reliable.
Stay away from GE products, or make sure you keep a backup refrigerator in your garage!
