Common Problems with the Hisense Portable Air Conditioner
#1 Front Display Screen of Air Conditioner is Blank
You may be surprised to see a blank screen on your Hisense portable air conditioner. Most air conditioners have LED screens that function as a control board, and where you can see the aircon settings in a convenient way.
When the LED screen is blank, it can mean one of three things: (1) the screen is dimmed, which is a setting you can activate or deactivate using the remote control; (2) the screen is on screensaver mode, and will light up once you change a setting on your AC unit; or (3) the screen is experiencing a computer glitch that may be resolved by pressing the reset button.
#2 Air Conditioner Not Blowing Cold Air
If the air conditioner is blowing hot air instead of cool air, check first if your AC unit is on a cool mode or a fan mode. A fan mode may not necessarily cool the air, but instead circulates the air in your room, therefore it takes on the temperature of the room air.
If your AC is on cool mode, but still won't blow cooling air into the room, then check your air filter. It may be dirty, which restricts the air flow in the unit, causing the warm air to flow into your room. Cleaning the filter should help cool the room air. Use a vacuum cleaner to clean the coils and vent hose as well.
#3 Air Conditioner Won't Operate
If your AC unit won't power on or operate at all, check the power cord first. Is it securely plugged into the wall? Are you having an electrical blackout? Had the circuit breaker tripped? These electrical issues may be the causes for your AC not working. Make sure the power cord is tightly plugged into the electric socket, and that the circuit breaker is functioning well.
#4 Air Conditioning Unit and Remote Control Miscommunication
Miscommunications between your portable air conditioning unit and its remote control may be due to low batteries in your remote control. Low battery power will cause the control board to lose its connection with your unit, which is why you may have a difficult time changing fan speed or cooling modes.
Change the batteries of your remote control, and make sure you're facing the remote directly towards the unit for the best connectivity. Remove any obstructions between the remote and your unit as these may hinder the connection.
How to Reset Your Hisense Air Conditioner
Reset Point: Power Button
Restarting your Hisense portable air conditioner may help fix most of the common issues you may encounter while using your unit. To restart your Hisense portable air conditioner, power the unit off, then unplug the power cord from its socket. Wait for 30 seconds, and plug the unit back in to power it on.
Your unit should reboot, and potentially fix any glitches, issues, or common problems with your unit. However, simply restarting your air conditioner will not fix a dirty AC, or flip a tripped breaker, which needs to be done manually.
Hisense Portable Air Conditioner Troubleshooting Guide
#1 Check the Error Code
Check the error code flashing on the screen of your portable air conditioner. The code should inform you of the problem with your unit, which you can narrow down by cross-referencing the error code with the owner's manual. Follow the troubleshooting steps that follow to fix the issue with your aircon.
#2 Clean the Air Filter, Drain Line, and Exhaust Hose
Cleaning your AC unit will help fix and prevent common AC issues. Clean the filter, drain line and pan, and exhaust vents thoroughly once every two weeks, or as needed. Portable AC units are relatively small, so they may require more frequent cleaning than wall-mounted or window units.
