Hi,

Please turn off ALL CAPS, it makes your question hard to read. The letters, when they're all the same size and general shape, tend to run together.

Okay, style points are out of the way. Now:

Thanks for including make and model number, that helps a lot and lots of askers don't include them here. However, I'm not finding an exact match for your model number. Are you sure that isn't ET1CHMXK Q09? Notice the third-to-last digit is a Q, not a 0. Double-check. All part numbers provided are assuming that model number has a Q, since the 0 didn't return any search results.

Did you check to make sure all the air circulation vents inside the refrigerator are open, not blocked? Ventilation inside the fridge is pretty important. Also check that the fan inside is working properly; a fan that quits means the items farthest away from the cooling coils will not be as cold as they should be, and stuff closest to the coils will freeze, even inside the fridge. If the ice is collecting as frost and clinging to sidewalls or the underside of where the coils are, I would suspect the fan first.

If the ice is collecting inside the freezer, especially close to or underneath the ice maker, that would suggest your water valve is leaking. With the ice maker bail in the OFF position, no water should make it through...and yet here we are. But if you have turned the water off at the supply valve, it won't be that. So let's move on to other possible sources.

The fan failing could be the fan motor, or it could be the defrost timer. You can check the fan motor by removing it and carefully plugging it in to an extension cord. It should fire right up. If it doesn't, new fan motor.

New fan motor for your fridge: part no. W10189703, about $48, easy to replace. Available at Sears Parts Direct (http://www.searspartsdirect.com/partsdirect/part-m... and probably locally.

If your fan works, there's a couple of defrost controls that can cause your difficulties, and they're easy to replace:

New defrost bimetal sensor, part no. 2321800. Sears Parts Direct link: http://www.searspartsdirect.com/partsdirect/part-n... About $27.00 This thing has a lot to do with keeping the frost drain clear. If your fan is good, check this next.

If the bimetal defrost sensor doesn't fix it, it could be your defrost controller is cooked. That's this: http://www.searspartsdirect.com/partsdirect/part-n... It's about $90.00

So you know, I have at times relied on Sears appliance service to keep my equipment in good nick. It's a little expensive and I already have all the tools and most of the know-how, but sometimes I just want someone else to do it. Sears has always been effective at repairing my stuff, and should serve you well if you decide these repairs are beyond your abilities.

Note: while you're in the fridge and working on stuff, take some time to get out the vacuum cleaner and the crevice tool, and just clean off any crud and lint that's blocking the fins or coils underneath. Airflow is important for devices that have to dump heat, and you can make your fridge a lot more effective and efficient by cleaning its coils every six months or so.
