main PCB

When the actual rotation number of the indoor unit fan
motor is below 1/3 of the target rotation number
continuously for more than 56 seconds.

Fan motor

Forecast of cause

Fan rotation failure

Fan motor winding open

Motor protection by surrounding temperature rise

Control PCB failure

Indoor unit fan motor failure

Check point 1. Check rotation of fan

Rotate the fan by hand when operation is off. (Check if fan is caught, dropped off or locked motor)
→ If fan or bearing is abnormal, replace it.

↓

Check point 2. Check ambient temperature around motor

Check excessively high temperature around the motor. (If there is any surrounding equipment that
causes heat)
→ Upon the temperature coming down, restart operation.

↓

Check point 3. Check indoor unit fan motor

Check Indoor unit fan motor. (Refer to indoor unit fan motor in

"Service parts information"

on page

03-36.)
→ If Indoor unit fan motor is abnormal, replace Indoor unit fan motor.

↓

Check point 4. Replace main PCB

If Check Point 1 to 3 do not improve the symptom, replace main PCB.
