4.11 Fan Motor Connector Check (Power Supply Cable)
Indoor 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.

Remove the X1A connector from the fan PCB (A2P) and measure the resistance between the
U and V, V and W, and W and U phases of the motor connector (with five conductors) and
check that each phase are balanced (within a permissible dispersion range of ±20%).
