11-10. How to Simply Judge Whether Outdoor Fan Motor is Good or Bad

1.Symptom

•Outdoor fan motor does not rotate.

•Outdoor fan motor stops within several tens seconds though it started rotating.

•Outdoor fan motor rotates or does not rotate according to the position where the fan stopped, etc.

Remote controller check code “02 : Outdoor block, 1A : Outdoor fan drive system error”

2. Cause

The following causes are considered when the outdoor fan motor does not normally rotate.

1)Mechanical lock of the outdoor fan motor

2)Winding failure of the outdoor fan motor

3)Position-detect circuit failure inside of the outdoor fan motor

4)Motor drive circuit failure of the outdoor P.C. board

3.How to simply judge whether outdoor fan motor is good or bad

Turn OFF the breaker.

Disconnect two connectors (CN300)

of the outdoor fan motor from the outdoor P.C. board.

Does the fan rotate without trouble when rotating it with hands?

		YES
	If the resistance value between
1	(Red lead)	–	2	(White lead)
2	(White lead)	–	3	(Black lead)
3	(Black lead)	–	1	(Red lead)

of the connector

(CN300 : Motor winding) is 17 to 25Ω, it is normal.

YES

Fan motor is normal.

(Outdoor P.C. board error)

NO

CN300

NO

Fan motor error

NOTE :

However, GND circuit error inside of the motor may be accepted in some cases when the above check is per- formed.

When the fan motor does not become normal even if P.C. board is replaced, replace the outdoor fan motor.
