Details of Self-Diagnostics

When the operation selector on the indoor unit is moved from the ON or TEST position to the OFF (Self-diagnostics)

position, the indicator lamps on the indoor unit will flash (or remain ON) for 5 seconds and then turn OFF for 2 seconds

(buzzer sounds once) to indicate the presence of a sensor failure or the activation of a protective function.

Self-diagnostics is completed when the buzzer sounds 3 beeps.

If there is no trouble, the lamps do not flash (illuminate). Also note that the corresponding parts listed below may not be

present in some models.

NOTE: If the operation lamp continues to flash (orange) even when the indoor unit operation selector has been moved

to the OFF position, an indoor unit external ROM failure has occurred. (E14)

After inspection or repair is completed, be sure to move the operation selector to the DEMO position, turn the

power ON, and erase the diagnostics contents.
