Nicole for Model Number GSH25SGPCSS

The refrigerator is freezing almost everything, top shelf, door shelves, bottom bins, etc. I turned down the refrigerator temp to the lowest setting of 1 and the freezer is at a low setting of 3. The damper door motor works because when I turn down the refrigerator setting to zero, I can see the damper door shut. Something seems to not be correctly regulating the refrigerator temperature because even at a setting of 1, the refrigerator always seems to be constantly running so the freezer never enters defrost mode, hence, the damper door is staying open the whole time. What could be causing this? Thank you!

Answer

Nicole, With the unit freezing and the damper door operating then you will want to test the thermistors of the unit. The thermistor should have a resistance reading of 5K ohms at room temp of 77 degrees, at 36 degrees it would be 14.4K ohms of resistance. If they are out of tolerance then the thermistor would need to be replaced.
