Cause
A Cycle Error occurs in LQC mode if the Defrost Sensor temperature does not drop below 3.5°C (38.3°F) within 10 minutes after the LQC test begins
Solution
Check the Defrost sensor. Check the frost pattern.
Frost Pattern:
A weak frost pattern will indicate a Sealed System issue, which will also keep the system from reaching the desired temperature in the specified time.
