Hi, this is a 5 ton unit you have. Is this L6 code coming from the indoor units circuit board? If so, remove the panel where you see this if there is a red led light that is blinking. It may kill power if you remove the blower panel as most have a kill switch for safety to shut all down when removed. To have the power on to check things you will need to tape this switch down good. I am not sure on your unit where you see this L-6 code, but on the panel there should be a trouble shooting chart telling you what this code is telling you. I know on gas furnaces they will tell you the problem. If this code is at the thermostat, you will need to go through the manual for programming it and it will say. Is the system cooling good, no problems that you have found? You might do what I have asked and if its on the stat check the manual. If you don't have one, get the name, Model, Serial numbers from the stat and call a appliance parts house not a sales show room, but a place that sell parts and they can look it up on there computer and tell you what the code is for that stat. Unless the unit has stopped cooling completely, I wouldn't worry to much, but would do your best to find out. If you can, let me know where you are seeing this code and how the system is working. This would be helpful for me. Please be kind when you go to rate me as that would be very kind of you. Please keep me posted on this unit. I will be around here if you need more help.
