E403 – Cold Weather Shutdown - Samsung RC090MHXEA Service Manual

E403 – Cold weather shutdown
E403 is a very, very rare error where the compressor refuses to kick in because the
temperature outside AND inside is too cold, it all comes down to where the remote controller
is located (If located in an unheated space, you'll find this fault). You'll also find this fault if you
have left the power off to the outdoor unit in cold weather for a long period of time.
