TROUBLESHOOTING

For ease of service, the systems are equipped with diagnostic code display LEDs on both the indoor and outdoor units. The indoor diagnostic display is
a combination of flashing LEDs on the display panel or the front of the unit.
Some indoor units display error codes specifying failure modes in outdoor units. If possible, always check the diagnostic codes displayed on the indoor
unit first.
The diagnostic codes displayed in the indoor and outdoor units are listed in the Table 8.
