Answer to "Freezer on bottom- floor filling with water & freezing/leaking out"If your refrigerator has a long panel inside in the back of the refrigerator I suggest removing it to see why the water does not drain. On mine a metal tab was wrapped around a heating coil to allow the water to drain and not freeze. Only trouble was the metal tab was not long enough to keep the water from freezing. Longer ones are available online that will solve this problem. I got one, installed it and it solved my problem.
Answer to "Freezer on bottom- floor filling with water & freezing/leaking out"And sometimes that cleanout will not help. Then the problem is a too short heating clip at the bottom of the heater inside the freezer. Got to take off the back panel inside the refrigerator to fix it but when you replace the short clip with a longer one that should do it.
