Several factors can cause poor cooling. Check if the air filter is dirty and clean it if necessary. Ensure there are no obstacles blocking the inlet and outlet. Verify that the temperature is set correctly. Make sure all doors and windows are closed. Use curtains to block direct sunlight. Reduce heat sources or limit the number of people in the room.
What to do if my Haier HSU-12LV03 does not work at all?
If your Haier Air Conditioner isn't working, check whether the power plug is properly inserted. Also, check if there is a power failure or if the fuse has blown out. Ensure the power supply is working correctly.
Why is my Haier HSU-12LV03 making noise?
Your Haier Air Conditioner might make different noises during operation. A swishing or gurgling noise is typically refrigerant flowing in the system. A cracking noise comes from the casing expanding or shrinking due to temperature changes. If you hear a big noise from air flow, check if the air filter is too dirty.
Why does my Haier HSU-12LV03 not restart immediately?
Your Haier Air Conditioner is designed to wait for 3 minutes before restarting after being stopped. This protects the system. Wait for 3 minutes before attempting to restart the unit.
Why does my Haier HSU-12LV03 generate smells?
