    Why does my Samsung AQ18A1QE Air Conditioner compressor and indoor fan stop in HEAT mode?
    • S
      Savannah KennedyAug 8, 2025
      In HEAT mode, the compressor and indoor fan of your Samsung Air Conditioner may stop intermittently if the room temperature exceeds the set temperature. This protects the compressor from overheating.

      If the indoor and outdoor fans of your Samsung Air Conditioner stop intermittently in HEAT mode, the compressor is operating in a reverse cycle to remove exterior ice.

      If the indoor and outdoor units of your Samsung Air Conditioner aren't linked correctly, check the link cable. Verify that the terminals are properly connected using the same number of cables for both units.

      Michelle AguilarAug 27, 2025
      If the compressor in your Samsung Air Conditioner stops intermittently in COOL or DRY mode, and the indoor unit fan speed decreases, this is likely to prevent the inside/outside air from freezing.

    Why is the compressor on my Samsung AQ18A1QE running when turned off?

      autumn64Sep 1, 2025
      If the compressor of your Samsung Air Conditioner's outdoor unit runs even when turned off in HEAT mode, it's likely because the de-ice function is active. The compressor will continue for up to 9 minutes to complete de-icing.
