Cleaning out the drain tube sounds like it would do it. However, your reply talked about "models" As best I can tell in my model, which I gave you, access to the drain tube led underneath the evaporator coils cannot be obtained by looking the evaporator coils, which cannot been seen by taking off the back panels. What I did do, finally was locate drip pan, which spread out under the compressor. I then located a flexible, open raceway which angled down from the top of the compartment which houses the compressor. By persistence I was able to bend this aside to locate slotted rubber nipple that yielded moisture. I took a very small cable tie and thrust upward to yield more moisture. Now drops! I was able to remove this nipple to reveal small section of hard tube protruding horizontally from the over head. I took a compressed air can and blew up in th tube.
The refrigerator has now been off for a couple of hours, ice on of freezer removed. I am going to put it back together, plug it into, turn it on and see what happen!
Get back if any comments. I will check back after the refrigerator is back together and on.
