Why is my Dux Comfort DUXHCS72 Air Conditioner not cooling or heating well?

  Natalie RobersonJul 30, 2025
  There are several reasons why your Dux Air Conditioner might not be cooling or heating effectively. It could be due to an inappropriate temperature setting, so ensure you set the temperature correctly. A blocked air filter can also cause this issue, so try cleaning it. Check if any doors or windows are open and close them. Make sure that neither the air inlet nor the outlet of the indoor or outdoor unit is blocked; clear any obstructions. Also, the compressor's 3-minute protection might be activated, in which case you should wait.

  If your Dux Air Conditioner doesn't start, there are a few things you can check: First, there might be a power cut, so wait for the power to be restored. Second, the unit may have become unplugged, so check that the plug is securely in the wall receptacle. Third, the fuse may have blown, so replace the fuse. Fourth, the battery in the remote controller may be exhausted, so replace the battery. Finally, the time you have set with timer may be incorrect, so wait or cancel timer setting.
