The freezer keeps running no matter what the setting. I replaced the control board and the thermistor. It use to only run on #2 setting before I replaced the thermistor now it runs all the time. If I need a thermostat, where is it located.
Answer Hello William,
You need to remove the rear cover in the bottom of the freezer compartment. If the coils are frozen up, the defrost thermostat 297216600 or the defrost heater 297348701 has failed. If there is no frost build-up on the coils, there is either a restriction, an inefficient compressor, or a leak in the sealed system. In either of the last three cases, a sealed system repair will be required to restore normal operation. This would require calling a freon certified technician. If the compressor isn't running at all, it could be the start relay on the compressor.
