We own a Frigidaire FRS6R3JW0 that is about 6 years old. Every 1-2 days, we have to remove the bottom drawer from the freezer and remove a solid block of ice from the evaporator tray so that water doesn't begin leaking onto our floor. We've had this repaired twice. The repairman melted the drainage tube (which was filled with ice) and ran a copper wire down the drainage tube to keep it from freezing/clogging again. We are now at the point where we are considering replacing the entire unit.
Our concern is this: The refrigerator sits in a space where it has less than 1/8" clearance on the sides. Is it possible that the lack of clearance around the refrigerator is what is causing this problem? Would the same thing happen with a new unit?
