That depends on exactly what the candidate means by "burnt out" but it is a red flag that warrants asking some deep and probing questions. If it's just shorthand for "I was tired of my old job", fine, that's not a problem, probably. If it's actually incapacitating or the candidate has a history of such, well, that would be very concerning. I've been in the throes of long-term burnout before and I know very well how hard it is to get anything done when that happens.
