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
