Answer to continue safely
Is it safe to keep using?
Maybe.
Can I reset the code?
Yes.
When to stop immediately?
Stop if you notice: The fridge compartment temperature exceeds 45°F for more than 2 hours, You notice food spoilage or unusual odors from the fresh food section.
Symptoms You May Notice
Refrigerator running too cold or too warm
The fresh food section does not maintain the set temperature — items may freeze unexpectedly or the compartment may be warmer than the setting indicates.
Temperature display showing unusual readings
The control panel displays an abnormally high or low temperature for the fridge section that does not match the actual conditions inside.
Compressor running continuously or not at all
Without accurate temperature data, the control board may run the compressor nonstop or fail to activate it, depending on the fault type.
Condensation on interior walls of fridge
Inconsistent temperature cycling causes moisture to accumulate on the interior surfaces of the fresh food compartment.
Possible Causes
Failed thermistor
The temperature sensor's internal resistance element has degraded or broken, producing inaccurate readings or an open/short circuit that the control board cannot interpret.
DIY PossibleLoose or corroded sensor connector
The wire connector between the thermistor and the main control board has worked loose or corroded from moisture, interrupting the temperature signal.
DIY PossibleMain control board fault
In rare cases, the input circuit on the main board that reads the sensor is damaged, causing the board to misinterpret a valid sensor signal.
Requires ProfessionalSafe Checks You Can Do
-
1
Power cycle the refrigerator

Tools required
When to Call a Professional
