E: 97. Outdoor Unit Fan Motor Error (Outdoor Unit) - Fujitsu ASYG07-14KGTF Service Manual

2-37. E: 97. Outdoor unit fan motor error (Outdoor unit)

Indicator Indoor unit
Detective actuator Outdoor unit
Forecast of cause
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 outdoor unit fan motor
Check outdoor unit fan motor. (Refer to outdoor unit fan motor in
page 03-89.)
→ If outdoor unit fan motor is abnormal, replace outdoor unit fan motor and main PCB.
Check point 4. Check output voltage of main PCB
Check outdoor unit circuit diagram and the voltage. (Measure at main PCB side con-
nector)
NOTE: For details of wiring diagram, refer to
TECHNICAL DATA AND PARTS LIST on page 02-121.

1. When outdoor fan rotation speed is less than 100
rpm in 20 seconds after fan motor starts, fan motor
stops.
2. After fan motor restarts, if the same operation within
60 seconds is repeated 3 times in a row,
compressor and fan motor stops.
3. If 1. and 2. repeats 5 times in a row, compressor
and fan motor stops permanently.
