(2) Outdoor fan motor

• Check resistance across the terminals of the

fan motor. (All terminals must be disconnected
from the unit.)

- High resistance between CF2-1 and CF2-2
- Medium resistance between RL09-NO and

CF2-2

- Low resistance between RL09-NO and CF2-

• If the resistance reading does not meet the

above conditions, replace the fan motor.

9.8 Inspection of Compressor

(1) Compressor motor

• Check resistance across the terminals of the

compressor motor. (All terminals must be
disconnected from the unit.)

- High resistance between S (Start) and R

(Run)

- Medium resistance between S (Start) and C

(Common)

- Low resistance between R (Run) and C

(Common)

• If the resistance reading does not meet the above conditions, replace the compressor.

(2) Overload relay

• Check for continuity across two terminals of the

overload relay. At normal temperature, there
should be continuity across the terminals.

• If there is no continuity across the terminals,

replace the overload relay.
