Have the kenmore 596.77609801.

Just noticed frost build up in the top back where the air blows in to the refrigerator. Temp reading 50 degrees and 0 in freezer. Freezer running fine no build up.

Fridge feels cold to me. Guessing might be a faulty thermostat or something?

That is where it frost builds up, but I don’t think it’s the issue. I thought someone had left the refrigerator open but today the temperature is showing 100 in the refrigerator when it’s probably 38

Could it be a bad thermistor?

 

[Jake]

Yes,

Its possibly the refrigerator section thermistor. You can Ohm test it by using a multimeter to ohm test its resistance. At room temperature (77*F) the thermistor should measure about 10K ohms.
