Summary

Preparation

Turn “OFF” the power supply
breaker, and remove 3P connector
which connects inverter and
compressor.

If fuse was blown, be sure to check
the electrolytic capacitor and diode
block.
(DB01)

Check

• Check whether 25A fuse on the

control board assembly is blown
or not.
(F01)

Check

• Connect discharge resistance

(approx. 100

, 40W) or soldering

iron (plug) b, – terminals
of the electrolytic capacitor
(500µF) of C08 (with printed
CAUTION
HIGH VOLTAGE) on P.C. board.

Operation

Turn on the power breaker, and
operate the air conditioner in COOL
mode by time shortening.

OK if 500µF

→

DC280 to 380V

Measurement Measure terminal voltage of the

electrolytic capacity.

Remove CN300 while pushing the
part indicated by an arrow because
CN300 is a connector with lock.

Check

After operation, turn off the power
breaker after 2 minutes 20 seconds
passed, and discharge the
electrolytic capacitor by soldering
iron.
Check voltage between motor
phases.

Stop

Check

Measurement

• Is not winding between [1]-[2]‚ [2]-

[3], or [1]-[3] opened or short-
circuited?

→

Resistance between

phases should be approx. 55 to
77

• Is not frame grounded with [1], [2],

or [3]?

→

Should be 10M

or more.

Replace
outdoor
fan motor.

Remove connector
of compressor.

YES

Check 25A fuse

(Part No.F01).

Does outdoor

fan rotate?

Replace fuse.

Check

electrolytic

capacitor, diode

block (DB01),

etc.

Check

electrolytic

capacitor, diode

(DB01),

etc.

Remove connector

CN300 of outdoor fan

motor, and using a

tester, check resistance

value between every

phases at motor side.

Check

terminal voltage

of electrolytic

capacitor.

Discharging position
(Discharging period
10 seconds or more)
