So what caused your air conditioner to stop working? Most likely, your AC system lost its charge of refrigerant. Or, due to an electrical fault, its compressor is not engaging when you turn on the system. Another possibility is that an internal obstruction is blocking the circulation of refrigerant.
When an AC suddenly stops working, the thermostat is usually the first thing you should check. Check the thermostat to see if it’s on. You can also try changing the temperature on the thermostat to see if that kicks the AC into operation. The location of your thermostat can also affect your AC.
The most common reasons could be a clogged filter, cooling fan problem, radiator trouble, or it could simply be that you need to recharge (regas) your air conditioning.
Why is my AC kicking on but not cooling?
If your air conditioner will turn on, and your thermostat is set properly, but your system is not cooling you may have a dirty or blocked air condenser. Your first step is to check the outside unit and clean around and remove any debris or weeds that are blocking air circulation.

Can a blown fuse cause AC not to cool?
It is possible that when the fuse of AC has blown, it can cause the entire system and functioning of AC to shut down because it cannot initiate cooling anymore.
How can you tell if your AC fuse is blown?
If there is the voltage on the “line” side, test for voltage on the “load” side of the fuses by placing the meter’s leads on the load wire lugs. If you read voltage on this side(220-240V), this means the current is flowing through the fuse. If you get a zero-voltage reading on the load, this means your fuse is blown.
The blown fuse will be apparent because the wire element within will have melted or burned from the higher electrical current. You can also use a test light or a multimeter to identify the dead fuse without having to pull it out. Both tools are affordable and easy to use.
Where is AC fuse located?
The fuse is a wire inside a glass casing, found in the disconnection box connected to your AC. The fuse is a protective measure meant to protect your air conditioner from electrical damage.

Can a fuse stop car AC from working?
There are several things that can cause electrical problems for your car’s air conditioning. These can include failed switches, a blown fuse, a problem with the control module or something else. Fuses can short out and make the A/C stop working or a loose connection can create an electrical short that is easily fixed.
The expense ranges from $30 to $300 for fuse replacement.
How do I reset my car AC?

Is there a fuse that controls AC?
When the summer heat is at its worst and you need your air conditioner the most, that’s when you’re most likely to experience a system breakdown. This is due to the fact that AC systems rely on fuses to operate, which are more susceptible to blowing out when temperatures are particularly high.
