I have a krmf706ess01 that is not cooling below 52 degrees in the refrigeration section but nice and cold in the freezer compartment. I have followed this other thread , https://www.applianceblog.com/mainf...ator-not-cooling-properly-ice-build-up.80067/ , and moved the thermistor to the proper location after finding that ice was building up on the condenser.

After I did this, the refrigerator was working well. After maybe 4 months, the cooling stopped again and so I pulled everything apart only to find that there was no ice on the evaporator at all. I have checked that the compressor is not hot to the touch but is running.

The evaporator fan in the refrigerator section is running ok and I have run Service Test - 2 RC Thermistor and got the code 01. I also ran Service Test - 5 Compressor Status/Speed to force the compressor to run at full speed and the refrigeration section evaporator got cold and confirmed the low temperature with a thermometer. Went below 14 degrees until my sensor could no longer read the low range.

All service tests for the thermistors had result 01 except for when I ran Service Test - 65 Pantry thermistor where the screen showed no result at all except for "Replace Filter" in red. Just heard some components turning on and off and some ticking.

Any help would be awesome!!

That would be the evaporator, not condenser.:) The evaporator is always inside the refrigerator and the coils get cold on it, the condenser is always outside the refrigerator and the coils get warm on it.

So if you have no frost pattern on the refrigerator evaporator now whatsoever, then that indicates a sealed system problem or 3-way valve problem and you will need to contact KitchenAid to come out at 1-800-422-1230 from that.

Thanks for the clarification.

So there are no voltage tests on the circuit boards to be done in this case? Everything points to the sealed system or 3-way valve and nothing else? The evaporator was cool during the diagnostic test that I performed in my initial post. It is just not cooling down to the 37 degrees under regular operation.

Not that I can see on the tech. data sheet, which I'm attaching below.

You can do TEST 4 which does check that 3-way valve.
