I need to find out how a temperature sensor in the refrigerator compartment is rated for this model. My understanding is that it should show a
certain amount of ohms resistance at different temperatures.
The heating element shows continuity, and the defrost thermostat also showed continuity with the freezer at 6 degrees F. I don't know the
temperature range of the defrost thermostat when it will open, but it should have operated to activate the defrost cycle before the coils iced over
(when I checked it, it was closed). So that leaves the temperature sensor malfunctioning or the main board has gone bad.
I don't want to replace the board if it could be the temperature sensor, or the defrost thermostat is bad even though it shows continuity.
So my request is really for a chart showing resistances for the temp. sensor. As always, I'm seeking advice from those whom have gone before. Thanks.
The freezer temperature was about 6 degrees F. when I got there and the fridge compartment about 48 F. Earlier in the day
the digital readout read -13F in the freezer and 55F in the fridge, so the owner raised the temp. in the freezer and the readout showed -2F and a corresponding 34F.in the fridge. However, my infared gun showed +6F and 47F.
Does this indicate a bad sensor, a bad control board, or both?
