Note
8.2 Indoor Fan Motor Connector Check
Check No.03
Fan motor wire breakdown/short circuit check
(1) Check the connector for connection.
(2) Turn the power off.
(3) Check if each resistance at the phases U - V and V - W is within specified range in the
table below.
Motor control voltage check
(1) Check the connector for connection.
(2) Check the motor control voltage is generated (between the pins 2 - 3).
Rotation pulse check
(1) Check the connector for connection.
(2) Turn the power on and stop the operation.
(3) Check if the Hall IC generates the rotation pulse 4 times when the fan motor is manually
rotated once (between the pins 1 - 3).
