I Had my GE frosting up everywhere inside..Kept defrosting and cleaning it out, and the same thing kept happening.
Went away for two months, and when I got home, it was all frosted up inside, and there was a huge chunk of ice by the ice dispenser…that’s when I noticed the ice dispenser flap was open! I worked it back and forth till I got it to close on its own again, and it has fixed my problem for now…I’ll have to see how to replace the flap and spring mechanism that shuts it..
