Why or what makes draining hole to accumulate ice that blocks drainage?
Is upper gets so cold that freezes condensed water in the channel and drain hole?
What newer upgraded probe looks like?
Can I upgrade the probe by myself and how to get that new probe?
The upgraded defrost probe looks like the older version, only longer. I suppose the older version wasn't long enough to actually do the job it was designed to do. Seems Samsung ignored the problem and didn't test enough.
I had A&E do the "repairs" so I can't speak with authority about how to obtain an upgraded defrost probe. A&E ordered the replacement parts and they all came from Samsung which A&E says controls the ordering process tightly. I would look in the Yellow Pages to find an appliance parts store to see if they can order the new probe.
I have no idea why the water freezes in the drain channel like it does. Maybe the drain channel is to close to the cooling coil. Maybe it is just a stupid design. Maybe Samsung just doesn't care what kind of crap they put out for sale. I just don't know. But I would agree that the reason is a combination of the three I mentioned with stupid design leading the way. How about it Samsung rep who reads here? What does Samsung intend to do? Nothing? Or something? I would bet the Samsung rep will say nothing at all!
BTW As an additional statement, I still have water dripping into the bottom of the refrigerator compartment after having service calls for over a year for the same problem.
