I've got a Frigidaire LGUB2642LE that I'm working on that has ice buildup on the rear wall of the refrigerator beneath the ice bin. The unit itself is not supplied with water at this time, so I know it's not the ice maker overflowing or leaking.
I seem to recall there was a service bulletin releating to this issue at one time but I can't seem to find it. The closest I can come to is concerning the front cover not fitting correctly, which isn't releated to this issue that I can tell. If anyone could point me in the right direction or give me an answer as to what's causing this/what the solution is, I would appreciate it.
