Howling noise in frig

FINALLY fixed this problem. It's NOT the fan motor. Tried that. It's NOT the control board. It's NOT how full you load the freezer or fridge. Mine is full. The problem is this: When they ship the units from the factory, there are two pieces of rubber trim that seal the left and right side of the fan box at the back of the freezer. During shipping, the trim slides down, exposing a 1" to 1/2" gap where air can get sucked in. This turns the fan box into a musical instrument. FIX: I simply put some electrical tape over the open spaces, and the howling stopped. It's been a week with no sound at all. Previously it howled all day, every day. The proper fix is to loosen the fan box and slide the trim back up into place, but putting tape over the gap will do the same thing and is easier. Enjoy your quiet kitchen! P.S. to GE: Please put some sealant on these gaskets before you ship them from the factory, so that they do not slide out of place during shipping. I'm sure they were silent when they left the factory, but you need to account for shipping. And inform your telephone staff of this fix. FINALLY fixed this problem. It's NOT the fan motor.
