I replaced the bimetal defrost thermistor, however that has not fixed the issue. Evaporator motor and fan tested in service mode, didn't come on, but within a half hour with the fridge running and freezer panel removed the fan kicked on and was sending. cool air to the refrigerator with the damper open. I also taste the damper. service mode and worked fine.

At this point, I am wondering if. its the refrigerator themister? or something else?

all. coils have been cleaned, compressor and fan running fine.

Ok, it looks like you have a sealed system problem, because all the evaporator coils should have a thin layer of frost on them from top to bottom, and your bottom coil doesn't.

Look at the very bottom photo below, and you will see what I mean.

Check your owners manual warranty, some models have up to a 10 year limited warranty on the sealed system/compressor.

You can contact KitchenAid at 800-422-1230 to come out to verify its a sealed system/compressor issue and if you are still in warranty, then they will pay for parts and you pay labor.
