Always make sure that your system is connected to the proper voltage. If the air conditioner responds to this remote you know that the other one is faulty and needs to be replaced. Your ac system is more than just the outdoor unit sitting by the side of your home. If the swing function on the split ac is not working there can be 2 reasons for this.

If your carrier air conditioning unit won t turn on there likely is an issue with its power source. If the coil froze the fan could be working but the air wont go through the ice until it melts. The next step is to check the led light on the top of the remote control. The indoor unit louver may not open or close due to obstacles around the louver or its unbalance during use.

Unfortunately air conditioners do break down leaving you stuck with rising temps and repair costs. Feel for air coming out of the vents. If you are not sure get a qualified technician to check your unit. If your mini split air conditioner or heat pump is not working also look for the error code that will show on display and use that code to identify the problem.

Most systems also include an indoor air handler unit usually a furnace or fan coil.

It is always a good practice to disconnect and isolate the power supply when you are troubleshooting the control board. A split air conditioner is also commonly known as ductless split or mini split where there is an outdoor unit and an indoor unit. Temporary malfunction of airflow direction can cause abnormal movement of the indoor unit louver. The indoor unit should include an air filter that traps dust dirt and other airborne particles.
