What to do if the Timer LED is on but my Samsung Air Conditioner won't turn on?
The timer is activated, and the unit is in ready mode. Cancel the timer operation for normal operation.
Why doesn't my Samsung MH052FVEA Air Conditioner cool when the room is hotter than the set temperature?
This can happen after a 3-minute delay when the compressor is re-operated, or when power is turned on.
What to do if my Samsung MH052FVEA Air Conditioner's compressor stops intermittently in COOL or DRY mode, and the fan speed decreases?
The compressor might be stopping intermittently, or the indoor fan speed might be decreasing, to prevent the inside/outside air from freezing, depending on the inside/outside air temperature.
Why does my Samsung Air Conditioner's compressor stop intermittently in DRY mode?
In DRY mode, the compressor operation is automatically controlled depending on the room temperature and humidity.
Why does the compressor and indoor fan stop intermittently in HEAT mode on my Samsung MH052FVEA?
To protect the compressor from overheated air in HEAT mode, the compressor and indoor fan will stop intermittently if the room temperature exceeds the set temperature.
Why do the indoor and outdoor fans stop intermittently in HEAT mode on my Samsung Air Conditioner?
In HEAT mode, the compressor operates in a reverse cycle to remove exterior ice. The indoor and outdoor fans do not operate intermittently for within 20% of the total heater operation.
Why is the compressor of the outdoor unit operating when my Samsung MH052FVEA Air Conditioner is turned off in HEAT mode?
When the unit is turned off while de-ice is activated, the compressor continues operation for up to 12 minutes (maximum) until the deice is completed.
What to do if my Samsung MH052FVEA indoor and outdoor units do not operate properly?
Check the terminals to ensure the indoor and outdoor units are properly linked by the same number of cables and that the connecting position on the terminal is correct.
