[sneaquie]

Not having too much luck with this reefer. Maybe I shouldn't have bought a 10 year old reefer trailer! Any help would be appreciated on these alarm codes.:o

Code 5 is ambient air sensor (usually found up near blower on top left hand side of unit.)
code 13 is sensor check.
Before discarding sensor check connection thoroughly.
