Part 6 Service Diagnosis
5.29.3 Outdoor Fan Motor Abnormality (10/12 HP Models)
Applicable
Models
RXMQ10/12AR
Error Code
E7
Method of Error
Detection
Abnormality is detected according to the value of current flowing through the inverter PCB
(or fan PCB for fan motor 2).
Abnormality is detected in the fan motor system according to the fan revolutions detected by
the Hall IC while the fan motor is running.
Error Decision
Conditions
Overcurrent is detected from the fan PCB (A4P, A5P) (system will shut down if detected 4
times).
Fan revolutions fall below a given level for a period of 6 seconds while in fan motor rotation
mode (system will shut down if detected 4 times).
Supposed
Causes
Defective fan motor
Failure to connect or defective connection of harness/connector between the fan motor and
the 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
Troubleshooting
Remove the foreign matter.
Correct the connection of
the relay connector.
Insert the connector.
YES
Is there
foreign matter in the
applicable fan?

Check the connection of connectors
Check the connections of all fan motor connectors.
Check the colors of the relay connectors
Check for any wire connection errors in both fan motors.
Fan motor 1: Power supply cables and signal cables are
red on the PCB side and white on the motor
side.
Fan motor 2: Power supply cables and signal cables are
all white.
Turn OFF the power supply, and then wait for a period of 10 minutes.
Some connectors
are disconnected.

Check for the motor (motor 1 or 2) applicable to the error
code
E7
while in monitor mode of the outdoor unit PCB.
Caution
Be sure to turn off the power switch before connecting or disconnecting
connectors, or parts may be damaged.
