My fridge is a KitchenAid 5 Door KRMF706ESS. Basically both the fridge section and the freezer section are running a bit warm. I have the fridge set to 37F and the freezer to 0F and it is in a ~77F environment. The ice maker in the fridge section is cold enough to freeze ice, but not cold enough to harvest it. (I read that it has to reach 16F to dispense the ice into the bin.) I ran a manual ice harvest using the Technician’s codes and all the components seem to be working properly. The freezer is also cold enough to keep things frozen, but ice cream is soft. I made sure the condenser coils were clear of debris, and both evaporator fans are running. The evaporator coils are not iced over. I initially repaired a faulty seal on the fridge door, but that has not solved my issue. My only other thought is possibly a low refrigerant level, but the compressor sounds normal (although it is hot to the touch) and the condenser coils are warm indicating what I assume to be proper refrigerant flow. Condenser fan is also working properly. Any help would be so appreciated! This issue is driving me insane. Thank you!
Hi, Don’t know about the ice maker, but looking at the parts for the refrigerator, there is a refrigerant valve (unit parts - part #6) which I believe distributes the refrigerant between the two evaporator units as required to get to and maintain the set temperatures. The freezer has a temperature sensor (freezer liner parts - part #9) so I was wondering if there was either a problem with the temp sensor (thermistor) indicating the temperature incorrectly or perhaps the control board or the valve. i.e. temp sensor signals the control board that operates the valve. If you have an Ohmmeter, disconnect the power from the refrigerator and then disconnect the freezer sensor and measure it’s resistance directly across the sensor leads. Hopefully it also has info to identify it so that the datasheet can be found to match the resistance reading to the temperature. Here’s an example of what I mean about what is shown on a thermistor datasheet. This is not for your temp sensor model as far as I know as this is in Celsius and not Fahrenheit and there are also 6 sensor models shown. The highlighted one was for information on another answer I provided for a different make and model refrigerator
(click on image to enlarge for better viewing) If it is the valve then the sealed system would need to be accessed and the refrigerant high/low pressures tested and maybe the refrigerant evacuated from the sealed system so that the valve can be tested/replaced etc. Not sure about where you are but have read that due to EPA regulations regarding the handling of refrigerant gases, a licensed repairer is required when working on the sealed system
