OUTDOOR UNIT DIAGNOSTIC GUIDES

For ease of service, the systems are equipped with a diagnostic code display LEDs on both the indoor and outdoor units. The outdoor
diagnostic is displayed on the outdoor unit microprocessor board.

There may be a few error codes displayed in the indoor unit that might relate to the outdoor unit’s problems. If possible, always check the
diagnostic codes displayed on the indoor unit first.

The diagnostic codes displayed on the outdoor units are listed on Table 10.
