The most common reason for a Carrier AC unit not working is a power supply issue. This can occur if the circuit breaker has tripped or if the fuse has blown, resulting in a loss of power to the unit. It is important to check the circuit breaker or fuse box and reset the breaker or replace the fuse if necessary.
Without a proper power supply, the AC unit will not function. Therefore, this is often the first aspect to investigate when troubleshooting a non-working Carrier AC system.
Additionally, a dirty or clogged air filter can restrict airflow, so check and clean or replace the air filter as per the manufacturer’s instructions. Clear away any debris around the outdoor condenser unit, such as leaves or dirt, and ensure that the condenser fan is operating correctly.
Low refrigerant levels can indicate a leak, so if the refrigerant is low, it may need to be replenished by an HVAC technician who can also inspect for any leaks. Faulty components like capacitors, relays, or fan motors can cause problems, and if suspected, it’s best to contact a professional HVAC technician for diagnosis and repair.
Finally, some AC units have safety switches that can trip if there is an issue, so refer to the unit’s manual or seek professional help to locate and reset any safety switches.

Why is my Carrier air conditioner not working?
If your Carrier air conditioner isn’t working, there are a number of potential reasons. First, check to make sure that the air conditioner is turned on and that the thermostat is set to “cool.” If the air conditioner is on and the thermostat is set properly, check to see if the condenser (the outdoor unit) is running.
When the condenser isn’t running, it could be because the power is off or because the condenser is frozen. If the power is off, check the circuit breaker or fuse box. Whether the condenser is frozen, turn off the air conditioner and wait for the ice to melt.
Once the ice has melted, turn the air conditioner back on and see if it works. If the condenser is running but the air conditioner isn’t cooling the house, it could be because the evaporator (the indoor unit) is frozen. If the evaporator is frozen, turn off the air conditioner and wait for the ice to melt.
Once the ice has melted, turn the air conditioner back on and see if it works.

Why is my AC on but not cooling?
One possible reason why your AC is on but not cooling is that the compressor isn’t working. The compressor is responsible for circulating the refrigerant throughout the AC unit, and if it isn’t working, the AC won’t be able to properly cool your home. Another possibility is that the AC unit is low on refrigerant.
If the unit is low on refrigerant, it won’t be able to cool your home as effectively. Finally, the AC unit might not be sized properly for your home. If the unit is too small, it won’t be able to properly cool your home.
