  If your Haier Air Conditioner isn't cooling well, several factors could be the cause. Ensure the air filter is clean; it should be cleaned every 15 days. Check for obstructions blocking the inlet and outlet. Verify the temperature is set correctly, and that all doors and windows are closed. Direct sunlight can also impact cooling, so use curtains. Finally, consider if there are excessive heat sources or too many people in the room.

  Your Haier Air Conditioner won’t restart immediately after being stopped. To protect the system, there's a 3-minute delay. This protection circuit also activates if the electric plug is pulled out and reinserted, preventing immediate operation for 3 minutes.
