Common Issues
The following problems are not a malfunction and in most situations will not require repairs.
Issue Possible Causes
Unit does not turn
on when pressing
ON/OFF button
The Unit has a 3-minute protection feature that prevents the
unit from overloading. The unit cannot be restarted within
three minutes of being turned off.
The unit may change its setting to prevent frost from forming
on the unit. Once the temperature increases, the unit will start
operating in the previously selected mode again.
The set temperature has been reached, at which point the
unit turns off the compressor. The unit will continue operating
when the temperature uctuates again.
The indoor unit
emits white mist
In humid regions, a large temperature difference between the
room’s air and the conditioned air can cause white mist.
Both the indoor
and outdoor units
emit white mist
When the unit restarts in HEAT mode after defrosting, white
mist may be emitted due to moisture generated from the
defrosting process.
Troubleshooting
The unit changes
from COOL/HEAT
mode to FAN
