Hello all,

I've read through a few threads to try diagnosing my refrigerator problem but was looking to get additional confirmation here. I have a KRFC704FPS03 refrigerator that does not seem to cool properly but the freezer works fine. I had a tech come out a couple weeks ago and he mentioned there was some ice buildup he removed, and I thought that fixed the problem, but only temporarily. 2 weeks later and the refrigerator still does not seem to cool properly and there is more ice buildup at the bottom of the RC. The previous threads I've looked at mention the RC or RC Evap thermistor being the culprit:


I thought the issue also might be the refrigerator not getting sufficient airflow. It's in a very tight space that the previous homeowner tried to make like a built in, so there is no gap on the sides of the refrigerator and maybe a half inch on the top. I took some diagnostics readings with the refrigerator both pushed in and pulled out, but the readings aren't consistent refer to tech sheet

The RC Thermistor seems to be consistently high. The RC Evaporator Thermistor was high but has gone lower since. Any other thoughts on this?

Really appreciate the help!

Its usually the RC evaporator fan motor and RC thermistor that fix this problem.

Look here:

Your model uses that exact same one, You can only get the RC thermistor only when you order the complete evaporator fan motor assembly:
