LED burnout is the least common cause of Carrier status light failure — but it's also the cleanest to confirm and the easiest to deal with. If you've ruled everything else out, this is probably where you are.
What LED Burnout Actually Looks Like
True LED burnout means individual LEDs stop illuminating. You might see a pattern with gaps — most of the dots lit, one or two dark. Or in a full burnout, the entire unit is dark with no response at all.
The unit will otherwise be in perfect condition: no cracked housing, no water behind the lens, no wiring issues, no installation problems. It's just used up. These units are in service 24/7 in all weather conditions — they eventually wear out.
Rule Everything Else Out First
Before calling it LED burnout, confirm the other causes aren't in play. The checklist is short:
If all of those check out and the unit is still dark, you're looking at LED burnout. At that point the unit needs to be replaced — there's no field repair for a burned-out LED array.
Warranty note
LED burnout is the failure mode most likely to be covered under warranty — there's no ambiguity about what caused it. If the unit is still within the warranty period, document the other checks before submitting the claim to show the failure wasn't caused by installation error or physical damage.The Replacement
