Had someone come out to check it and of course it worked fine. Very frustrating to find food sitting in a too warm fridge.
Your model is all controlled by the electronic circuit board. The thermistor (or what some would call the thermostat) tells the circuit board what the temperature is inside. This one thermistor work for both the gas or electric mode. So if yours workers well on gas mode the thermistor is not the problem.
So if it is cooling then not cooling on electric mode, you have three choices.
1. A loose connection where the heating element plugs into the circuit board.
2. A bad heating element. (yes they can work sometimes and not others).
3. A bad circuit board.
I would check the warranty for sure.
