Thanks for your suggestions! As a note the water accumulation is about 1/4 - 1/2 cup per 24 hr. I collect it in a dish under the "cup area" in back of fridge under freezer compartment (I have a 7 yr old top freezer fridge).
I don't have ice or water dispenser so not an issue.
I get the part about the tray (assume you mean pan under fridge) and will investigate that one. However, I have never had water on the floor so think this is OK.
Did a not so good job cleaning out the dust from coils underneath fridge but will do a better one.
The tray, or better yet the trough, I was talking about is the one underneath the coils inside the freezer (I took the back panel off). This only guides the water to the drain area (with styrofoam around it) that then goes into the back of fridge, down the drain line to the drain pan under the fridge. This one is totally clear, no ice buildup, etc. (of course when I opened it I had the electricity off so it might have melted very fast?) However, I do feel this is the problem area...water cannot drain fast enough from this trough down to the drain line.
The seals are great...cannot see light or pull paper through.
I'll try cleaning the tray and coils on the bottom of fridge and let you know. I am discouraged though. It seems to truly be coming from the freezer to the fridge up top.
