11-7. Trouble Diagnosis by Outdoor LED

For the outdoor unit, the self-diagnosis is possible by five LEDs (Red).

•LEDs (Red) (D11 to D15) are provided on the sub- control board under surface of the inverter, and as shown below, they are checked from the wiring port when removing the wiring cover.

(1)If a trouble occurs, LED (Red) goes on according to the trouble as described in the table below.

(2)When two or more troubles occur, LEDs go on cyclically.

(3)Usually, LEDs (Red) go off.
