4.11 Fan Motor Connector Check (Power Supply Cable)
CHECK 16
Check the fan motor connector according to the following procedure.
Outdoor Unit
1. Turn OFF the power supply.
2. Measure the resistance between phases of U, V, W at the motor side connectors (3-core wire)
to check that the values are balanced and there is no short circuiting, while connector or relay
connector is disconnected.
Indoor Unit
FXFQ-AA
1. Turn the power supply OFF.
2. Disconnect the fan motor connector from the PCB and measure the resistances between U-V,
V-W and W-U.
Judgment: Resistances must be balanced within 20%.
FXDQ-M, FXHQ-M
1. Turn OFF the power supply.
2. Measure the resistance between phases of U, V, W at the motor side connectors (3-core wire)
to check that the values are balanced and there is no short circuiting, while connector or relay
connector is disconnected.
