11-6. Trouble Diagnosis by Outdoor LED

For the outdoor unit, the self-diagnosis is possible by
LED (Yel) and four LEDs (Red).

• LED (Yel) (D800) and LEDs (Red) (D801 to D804) 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 or Yel) goes on accord-

ing to the trouble as described in the table below.

2. When two or more troubles occur, LEDs go on cycli-

cally.

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