Display shows E0; refrigerator may continue to run but temperature control is unreliable.

Safety first: Unplug the refrigerator before accessing any internal wiring or control boards.

• Power cycle: Disconnect power for 5–10 minutes, then restore. If E0 clears and does not return, it may have been a transient error.
• Inspect harness connections: Access the main control board (usually at the rear or top). Check that all sensor harness plugs are fully seated and free of corrosion.
• Check thermistors: Using the tech sheet (often behind the toe grille or rear panel), identify thermistor test points. Measure resistance at room temperature and compare to the chart. Replace any sensor that is out of range or open/shorted.
• Replace control board (if necessary): If all sensors test good and wiring is intact, the main control board may be defective and require replacement.
