Part 6 Service Diagnosis
5.28 Outdoor Fan Motor Abnormality
Applicable
Models
All outdoor unit models
Error Code
E7
Method of Error
Detection
Detect according to the value of current flowing through the inverter PCB (or fan PCB in
case of fan motor 2).
Detect error of the fan motor system according to the fan revolutions detected by the Hall IC
during the fan motor runs.
Error Decision
Conditions
When overcurrent is detected from the inverter PCB or the fan PCB (Detecting overcurrent 4
times will shut down the system).
When the fan revolutions fall below a given level for a period of 6 seconds while in fan motor
rotation mode (Detecting shortage of revolutions will shut down the system).
Supposed
Causes
Fan motor failure
Disconnection of harness/connector between the fan motor and the fan PCB
Fan does not rotate due to foreign matter caught in it
Clearing condition: fan motor performs normal operation for a period of 5 minutes
