TROUBLESHOOTING

For ease of service, the systems are equipped with diagnostic code

display LEDs on both the indoor and outdoor units. The outdoor

diagnostic display consists of two LEDs (Red and Green) on the

outdoor unit board and is limited to a few errors.

The indoor diagnostic display is a combination of flashing LEDs

on the display panel or the front of the unit. If possible, always

check the diagnostic codes displayed on the indoor unit first.
The diagnostic codes displayed on the indoor unit are listed in

Table 8.
