3.37 Outdoor Fan Motor Abnormality
3.37.1 Outdoor Fan Motor Abnormality (REYQ-XATJU(A), REYQ-XAYDU(A))
Applicable
Models
REYQ-XATJU(A), REYQ-XAYDU(A)
Error Code
E7
Method of Error
Detection
Detects according to the value of current flowing through the inverter PCB (or fan PCB in case
of M2F).
Detects error of the fan motor system according to the fan revolutions detected by the Hall IC
during the fan motor runs.
Error Decision
Conditions
Overcurrent is detected from the inverter PCB or the fan PCB (Detecting overcurrent 4 times will
shut down the system).
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
Neglect 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
There are
foreign matter around the
applicable fan.
Remove the foreign matter.
YES
Check for the connections of all fan motor connectors.
NO
Turn OFF the power supply, and then wait for a period of 10 minutes.
Some connectors are
disconnected.
Insert the connector.
YES
NO
NO
There is a relay
connection error.
Correct the connection of the
connector.
YES
Caution
Be sure to turn off the power switch before connecting or disconnecting
connectors, or parts may be damaged.
A
Check for any wire connection errors in 2 units of fan motors.
M1F: Power supply cables and signal cables are all white.
M2F: Power supply cables and signal cables are red on the
PCB side and white on the motor side.
Check for Connection of Connector
Check for Colors of Connectors
Outdoor units are equipped with 2 fan motors.
Check for M1F or M2F applicable to the error code
E7
while in
monitor mode of the outdoor unit.
