Joe for Model Number RSG257AARS/XAA-0000 I first notice an issue when our ice cream would melt even after power freezing the freezer or lowering the temp to -4 in the freezer. The temp on both sides are lower than what the temp is showing on the displays screen. I manually measured the temp with a thermometer and the freezer only gets up to 28 degrees even though the it says it's -4. The refrigerator only gets up to 42 even though it says it's 34. I first thought it was the compressor and replaced the compressor relay protector (DA34-00004D). The compressor is cycling on/off and running. I then checked both coil motor fans inside the freezer and refrigerator and they are running. I then checked all four of the temperature sensors and they showing 13K ohms of resistance when I place them in ice water. Even though I thought 16K is the correct amount of resistance when the temperature is 32 (F), I'm assuming 13K is correct since all four temperature sensors can't be bad. I did notice that the coils are not icing up all the way, so I'm assuming that's reason why it's not getting cold enough. The compressor/compressor lines have not been compromised, so I'm assuming the Freon levels are fine. Any help would be appreciated. Thanks Joe
Answer Joe, For this issue you would want to test the temperature sensors to make sure that they are good. At room temp the resistance should be 5K ohms. If the temp sensor is good then you will want to check the frost pattern of the freezer compartment. If the frost pattern is very little frost then the issue will be a sealed system in which you will need service to diagnose the issue. Read More...
