Cause : Cooling fan feedback missing.
1. Check the auxiliary code to identify the fan.
Code 0 denotes main fan 1.
Other codes (format XYZ):
“X” specifies state code (1: ID run, 2: normal).
“Y” = 0,
“Z” specifies the index of the fan
(1: Main fan 1, 2: Main fan 2, 3: Main fan 3).
Check fan operation and connection.
Replace fan if faulty
