Judgment and action

1. Check thermo. sensor.

2. If it is OK, check P.C. board.

1. Check heat exchanger

sensor.

2. If it is OK, check P.C. board.

1. Disconnect the power plug

from AC outlet, and pull out
the connector (CN10) for the
motor, then connect the plug
of AC power cord again and
turn the power on.

2. Check the voltage between

pin 1 and 2 of the connector
(CN10).

3. If the output voltage is 35V,

P.C. board is OK, check
motor.

Replace P.C. board.

1. Check connective cable

correct if wiring is wrong.

2. Check thermal fuse and

Terminal blocks.

3. If it is OK, check P.C. board.

1. Check gas quantity.

(check gas leakage)

2. If it is OK, check heat ex-

changer sensor.

3. If heat exchenger sensor is

OK, check overload relay and
thermostat for compressor.

4. If overload relay and

themostat for compressor
are OK, check refrigerant
cycle.

5. If refrigerant cycle is OK,

check P.C. board.

1. Check compressor.

2. If it is OK, check P.C. board.
