#1 What do the flashing LED error codes on my Criterion refrigerator mean, and how can I fix them?
The flashing LED indicators on your Criterion refrigerator point to specific sensor or communication issues. Here’s a breakdown of the common error codes and their meanings:
LED1/LED2 flashing: This indicates a refrigerator temperature sensor fault. Check the refrigerator’s temperature sensor to ensure it is functioning properly or may need replacement.
LED1/LED5 flashing: This points to a freezer temperature sensor fault. Inspect the freezer temperature sensor for potential issues or replacement needs.
LED1/LED3 flashing: This indicates a freezing frost sensor fault, meaning there may be a problem with the sensor responsible for detecting frost buildup in the freezer.
LED2/LED4 flashing: This signals a communication failure between internal components of the refrigerator. Check for any loose or damaged connections and restart the unit.
LED1/LED4 flashing: This error refers to an ambient temperature sensor fault, meaning the sensor responsible for measuring the external environment's temperature may be faulty or disconnected.
