Our Kenmore Elite Trio Refrigerator Model number 59676593600 (Amana) is stuck in defrost mode, third time. Sears replaced Touchpad twice, defrost sensor, therm sensor once. Waiting the two weeks till they come (perhaps without part! ) and the fridge is starting to stink, door heaters are hot, tried unplugging. Are there touchpad codes to kick it out of defrost? Any diagnostic codes so as to not be at the BlueGuy’s mercy, and actually know what’s failed?

There are three components to the defrost cycle on your refrigerator. The control board, defrost thermostat, and the defrost heater. When replacing the control board on that model you have to program it so that it works properly with your model. If it wasn't programmed correctly, that could cause an issue. Other than that you could have a short somewhere in the system, causing the heater to run when its not supposed to. If that's the case then it might not be repairable if the short is somewhere in the cabinet where its not serviceable.

There are no codes on that refrigerator.
