Carrier split ac indoor unit not working.

It is always a good practice to disconnect and isolate the power supply when you are troubleshooting the control board. Temporary malfunction of airflow direction can cause abnormal movement of the indoor unit louver. If the coil froze the fan could be working but the air wont go through the ice until it melts. The next most common step in ac troubleshooting is checking for a dirty air filter.

Air conditioning units cost a lot to repair and replace. Even if the system is correctly wired to the proper voltage issues can still occur depending on your electric service. If your carrier air conditioning unit won t turn on there likely is an issue with its power source. The indoor unit louver may not open or close due to obstacles around the louver or its unbalance during use.

The vast majority of mini split units require 208 230 volt service but there are some that will work with 115 volts. Most systems also include an indoor air handler unit usually a furnace or fan coil. Always make sure that your system is connected to the proper voltage.

If the fan isn t working that can cause the coil to freeze. The next step is to check the led light on the top of the remote control. Either the pcb is not sending current to the motors or motors have a problem. Check the outdoor cooling or condensing unit to see if it s running.

If you have another remote in the house that you use for another same brand split air conditioner you can try it on the unit that s not working. And while it s never convenient to have a broken air conditioner a yearly inspection and tune up can prevent future problems. If it is in the air conditioning mode check for ice around the evaporator coil and on the refrigerant lines at the indoor 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.

The indoor unit should include an air filter that traps dust dirt and other airborne particles. The swing is controlled by separate swings motors. If you are not sure get a qualified technician to check your unit. Airflow direction control may not be engaged with the universal remote control.

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