Samsung AC Troubleshooting




Trouble: The operation is not done




Cause and reason:

  1. Is the power off or the power unplugged?
  2. Does it stop because it is the completion time?
  3. Unplug and plug again the power source for 2 minutes.

Trouble: The wind comes out but the heating/cooling is not performed.

Cause and reason:

  1. Is the filter clogged with dust or dirty?
  2. Is there any direct light on the outdoor unit or any obstacle against it?
  3. Is the selected temperature too high? Lower the selected temperature lower than the current one (during cooling).
  4. Is the selected temperature too low? Raise the desired temperature than the current one? (during heating)
  5. Is the “Fan only Mode” operation?

Trouble: The remote control does not operate

Cause and reason:

  1. Is the battery run out?
  2. Is the battery inserted in the wrong way(+, -)?
  3. Is the detection part of the indoor unit blocked?
  4. Does it interfered with the radio of neon sign?

Trouble: The wind volume is not adjusted

Cause and reason:

  1. Is the operation selected among one of Auto / Dry / Turbo / Sleeping?
  2. The temperature setting is not required since the wind volume set automatically.
  3. Check again at the state of Cooling / Fan only / Heating.

Trouble: The temperature is not set

Cause and reason:

  1. Is the operation selected among the Dry / Turbo / Sleeping / Fan only Mode. Since the temperature is automatically set, the temperature setting is not required.
  2. Check again at the cooling / heating state.
  3. The standard temperature ±2˚C during the automatic operation

Trouble: The operation lamp continues to be flickering

Cause and reason:

  1. Push the Operation / Stop button.
  2. Unplug and plug the power source.

Trouble: The immediate operation starts without control of remote control when plugged

Cause and reason: It is the case that the auto restart function works. Auto restart function is the convenient function where the operation state is memorized in the Memory IC during the blackout and the operation restarts when the power comes back
