Why my Samsung Air Conditioner does not operate at all?

  Jaime BrownAug 22, 2025
  Your Samsung Air Conditioner might not be operating because the power plug isn't properly connected. Ensure it's securely plugged in. Also, check if the auxiliary power switch (MCCB, ELB) is turned on. If it's off, the air conditioner won't work even if you press the power button. Remember to turn the auxiliary power switch on 6 hours before starting operation after an extended period of disuse. If the air conditioner is turned off by the Timed off function, turn it on again by pressing the power button.

  If your Samsung Air Conditioner's wireless remote control isn't working, first check if the batteries are discharged and replace them with new ones. Ensure that nothing is blocking the remote control sensor. Strong light from fluorescent bulbs or neon signs may interfere with the remote control, so check for any nearby.

  If your Samsung Air Conditioner isn't cooling or warming enough, check the set temperature. In Cool mode, if the set temperature is higher than the current temperature, cool air won't come out. Press the Temperature button to set it lower (minimum 18°C). In Heat mode, if the set temperature is lower than the current temperature, warm air won't come out. Press the Temperature button to set it higher (maximum 30°C).

  Warm air may not be coming out of your Samsung Air Conditioner if the outdoor unit is designed for cooling only. In this case, warm air won't come out even if you select the Heat mode. Also, ensure that the remote control supports both cooling and heating. If it doesn't, use a remote control that does.

  The temperature on your Samsung Air Conditioner may not be changing because it could be running in Fan mode. In Fan mode, the air conditioner controls the set temperature automatically, and you cannot change it.
