Model ET22DKXFW00

OK, I have literally taken apart the inside of my freezer at this point. The bottom sliding tray, the side light, the ice maker, all out so I can slup the back panel out enough to see the evaporator coils, the fan, and the tray. There were tons of ice. And so, with the unit unplugged, I thawed the ice blowing hot air and sopping up the water.

There appears to be a small drain hole beneath the area where the sliding tray was -- hard to tell. No sign that water drains, and quite honestly, water from the evaporator tray does not flow down to it (the path of least resistance appears to be into the fridge).

Based on prior posts, I am going to see if all this defrosting clears up the problem. I did have three questions:

First, am I looking at a frain hole, and where does it go from the center of the freezer cabinet? All I seeon the back of the unit are the supply lines for the water to the icemaker.

If it is, then how and where would one blow air through it to remove any blockage that is debris?

Last, what is the purpose of the fan? When should I see it opearte? How would I know if it is bad? And, could this be the cause of ice build-up?

Here's a schematic of what your fridge looks like part wise. You should be able to locate exactly what the drain line does and where it goes by just consulting this schematic.

Why exactly did you tear your fridge apart? Was it due to not defrosting properly? Then the problem is either:

1. Defrost heater faulty.
2. Defrost limit switch faulty.
3. Defrost timer faulty.

I don't think it has anything to do with a drain line at all if all the cooling coils on the inside have frosted up.

Thanks for your response.

The problem began with water appearing in the refigerator compartment, on each of the shelves, even forming ice in the fridge.

Based on other threads, I was led to think a drain was blocked.

I took the ice maker out to remove the other parts in the freezer, so that I coldl see what was up.

There is a sliding tray on the freezer floor. When I removed this, I found an enormous build up of ice toward the back wall. I removed the light on the right, so that I could slide the back panel off. That revealed a complete build up of ice in the metal pan below the coills, and ice wedged in under the pan.

I had the unit unplugged, and I blew warm air at the ice to melt it. It just puddled up, so I used towels to sak up the water, until all of the ice melted, and all was dry.

By the way, no coils themselves were in ice, or appeared frosted... just the metal tray area below the coils.

I have since buttoned it all back up. Weare really talking about the removal of a total of nine screws in total,, sorry if it sounds like I literally tore it apart...

What I have noticed is this:

No water inside the fridge -- that is the good news.

The freezer and the fridge are cold, but not as cold as before my attempt to repair... so I have set the temp control to a colder setting for each.

The ice maker is not filling... not sure why... I can figure that out later.

I have yet to see the fan operate. Hence the question about the fan.

I am finding the schematics informative, but also a bit hard to read/locate any drain anywhere.

OK, the entire fridge and freezer are losing their abiliity to cool effectively.
