Carrier Split Ac Indoor Unit Not Working

Your ac system is more than just the outdoor unit sitting by the side of your home.

Carrier split ac indoor unit not working.

If the swing function on the split ac is not working there can be 2 reasons for this. It is always a good practice to disconnect and isolate the power supply when you are troubleshooting the control board. Feel for air coming out of the vents. 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. And while it s never convenient to have a broken air conditioner a yearly inspection and tune up can prevent future problems. The swing is controlled by separate swings motors. The next most common step in ac troubleshooting is checking for a dirty air filter.

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 vast majority of mini split units require 208 230 volt service but there are some that will work with 115 volts. A split air conditioner is also commonly known as ductless split or mini split where there is an outdoor unit and an indoor unit. Poor performance in both heating and cooling modes an insufficient refrigerant level is the leading cause of reduced ac efficiency and performance.

If your carrier air conditioning unit won t turn on there likely is an issue with its power source. Either the pcb is not sending current to the motors or motors have a problem. Make sure the main power. Check the outdoor cooling or condensing unit to see if it s running.

If it is in the air conditioning mode check for ice around the evaporator coil and on the refrigerant lines at the indoor unit. Always make sure that your system is connected to the proper voltage. The next step is to check the led light on the top of the remote control. Even if the system is correctly wired to the proper voltage issues can still occur depending on your electric service.

If the air conditioner responds to this remote you know that the other one is faulty and needs to be replaced. If you are not sure get a qualified technician to check your unit. If the fan isn t working that can cause the coil to freeze. 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. If the coil froze the fan could be working but the air wont go through the ice until it melts. Airflow direction control may not be engaged with the universal remote control. Air conditioning units cost a lot to repair and replace.
