Ok Guys - this is embarrassingly simple:
We had a construction worker accidentally unplug a basement fridge. By the time we discovered - lost all the vennison I had in the freezer.
Went to clean the freezer defrost drain that runs all along the bottom and it looks like I have to take the doors off their hinges and peal back the sides so I can pull the freezer floor panel out to clean the drain?
Seems like a lot of work for a simple cleaning maintenance... pls tell me I'm upside down on this!
