Frequently Asked Questions
Common questions about GE CC error
The CC error on the GE GFE28GYNFS indicates a communication failure between two internal control boards. Modern refrigerators have multiple electronic boards that communicate with each other to coordinate cooling, defrost, and ice making. A 5-minute power reset often resolves a temporary communication glitch caused by a power fluctuation.
Possibly. A communication failure between boards can prevent the compressor and fans from receiving proper commands, which may reduce or stop cooling. Move temperature-sensitive items such as meat and dairy to a backup cooler while troubleshooting the CC error to prevent food spoilage.
