Hisense Portable Air Conditioner Not Cooling – Troubleshooting

It is a law that whenever you come across any issue then it is important to first define the problem and then jump to its fix. This approach will help you to solve the problem more quickly. Secondly, it will give you a proper understanding regarding the problem. So before anything else, it is important to first carry out some basic troubleshooting.

1. Checking the Power to Unit

The very first thing to check is whether your air conditioner is getting enough power or not. As soon as you press the power button the lights and fan should receive power.

2. Checking the Electrical Plug

In your built-in breaker, there should be a test and reset button present. You first need to press the test button in order to trip the breaker and then you need to push the reset button firmly. Lastly, turn on the air conditioner and run a test.

3. Checking the Power Outlet

Most importantly, you need to check the power to the outlet as well. Make sure that the wall switch isn’t turned off and the breakers in your household electrical panel are working fine.

4. Checking the Mode Setting

Many air conditioners have three settings; Dry, Fan and Cool. You need to make sure that the AC is set to cool mode. Secondly, you need to turn the air conditioner thermostat below room temperature so that the system gets activated. The system will take some time before starting the cooling cycle.

5. Fan Hurdles

Another important thing is to check the fan grills for obstruction. Take a flashlight and flash it into the openings of the fan. If you find any obstruction then remove it immediately.

6. Checking the Water Tank

You will notice that there is a warning indicator present which will indicate you immediately when the internal tank is full. If your AC shuts off suddenly and beeps then a full water tank is usually the reason behind it. What you need to do is hold the unit and pour out the water present in it. But you need to be extra careful as portable ACs are heavy.

7. Checking the Error Codes

In case you see an error code on the display, you need to immediately interpret its meaning by consulting your user manual. As soon as you are aware what the error code means then you need to find its solution and apply it without wasting any time.

Troubleshooting Guide for Poor Performance

If the problem isn’t with your AC but its performance then there are different troubleshooting steps that you need to carry out. Set the AC mode to “Cool” and wait for the compressor to start. It will take 60-90 seconds to power up.

Check the air temperature that is flowing out of the top of the unit and the air flowing into the evaporator coil behind the top filter grill at the back. If the air temperature is hot then follow the below-mentioned steps to improve its performance.

  • If you haven’t cleaned your air conditioner for quite some time then I insist you take out the filters carefully and use a blower or a soft-brush to clean them.
  • Next you need to check the evaporator coil, if there is any frost build-up then you need to remove it immediately.
  • Lastly, you need to check the exhaust hose for blockage and kinks. Hot air should get out of the vent so that the air conditioner can blow cold air.

Troubleshooting Guide for Improving Efficiency

Now comes the troubleshooting steps related to improving efficiency. Carry out the below-mentioned steps in order to improve your air conditioner’s performance.

  • Place the vent hose in such a place where it remains straight and short. This way the heat will get out easily.
  • Make sure that the air hose isn’t damaged because it is responsible for carrying out the heat you are trying to get rid of.
  • If there is any type of leakage present in the window bracket then the air will leak out of the hose joint. This will eventually decrease the performance of your air conditioner.
  • Ensure that the AC is placed somewhere where there is less sunlight as direct sunlight can add 10% heat to the room. Insulate your windows with curtains or shades to get rid of this issue.
  • You need to close the windows and doors of your room when the AC is on. If you don’t do this then eventually the cold air will leak out from the room.
  • After insulating your doors and windows, you need to insulate the outside of the air hose as well. This can create an improvement in the performance of your Air Conditioner.
