Possible Causes
The unit has a 3-minute protection feature that
prevents it from overloading. The unit cannot be
restarted within three minutes of being turned off.
In Cooling and Heating Models: if the Operation
light and PRE-DEF (Pre-heating/ Defrost)
indicators are lit up, the outdoor temperature is too
cold, and the unit's anti-cold wind is activated in
order to defrost the unit.
The unit changes its setting to prevent frost
from forming on the unit. Once the temperature
increases, the unit will start operating again.
The set temperature has been reached, at which point
the unit turns off the compressor. The unit will resume
operating when the temperature fluctuates again.
