Unless you are familiar with the BASICS of REFRIGERATION...
" ERROR CODE means it is "Out of ORDER
Broken: Needs repair.
By searching the internet "split A/C " It defines a
COMPRESSOR overload protection

SAVE your equipment FROM SELF DESTRUCTION.
detail sheet (below)
Is the heart of MOST modern refrigeration systems.
In a SPLIT system it is the outside unit with the FAN
that should be running when the COMPRESSER is
in action. Typically then compressed & COOLED
REFRIGERANT is then piped into a cooling element
LIKE MOST REFRIGERATORS where the
cooling takes place (expansion valve and evaporator).
Treated AIR (indoor) is then blown through the
evaporator... cooling the room and warming the
refrigerant (which continues to cycle back to the
outside unit where the compressing cycle
continues until the INSIDE temperature is
achieved... (thermostat on the wall)
pretty much means EVERYTHING but those combined refrigeration units seen WORLD-WIDE
HANGING OUT OF WINDOWS... or on roof-tops with DUCTING for
" to be pumped where needed.
Similarly heat pumps
simply have reversible valves...
which turn the coils around (functionally).
There too are split-system
(inside/outside) & combined units.
