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 before consulting a service technician. 

The diagnostic codes, displayed in the indoor and outdoor units, are listed in Table 15

.
