# AC Unit Not Turning On – Causes & Fixes
When the air conditioner in your home or office isn’t turning on even after you have made all the necessary checks, the very first thing you need to do is determine the cause of the problem. In some cases, the AC may be simply underpowered or not be set up correctly. In other cases, the problem could be more serious, such as an internal system malfunction or damage due to a power surge. Regardless of the issue, understanding the causes and possible fixes for an AC unit not turning on can help you get your unit up and running again.
## Common Reasons Why Your AC Unit May Be Not Turning On
There are many potential causes for an AC unit not turning on, including:
### Power Issue
The very first thing you should check when your AC is not turning on is the power source. This includes checking the main power cord to make sure it is securely plugged into a working outlet, as well as checking the circuit breaker to ensure the AC unit hasn’t been tripped. If there is no power reaching the unit, the issue could be a loose connection, faulty wiring, or a blown fuse.
### Compressor Malfunction
If the AC compressor doesn’t kick in when you turn the AC unit on, it could be caused by any number of issues. These include a faulty capacitor, worn out start capacitor, faulty compressor wiring, and a defective compressor.
### Blocked System
Sometimes, a blocked system may cause the AC not to turn on. This is often due to a blockage in the return line, which can occur due to a buildup of dirt and debris. Additionally, the refrigerant line may be blocked due to clogs from algae or microbial growth, or due to blockages resulting from a puncture or other damage.
### Loss of Charge
If your AC unit isn’t turning on, the unit may have lost its charge due to a leak in the refrigerant component of your AC. This can occur due to an aging system, a punctured line, or an improper installation.
## Ways to Troubleshoot Your AC Unit
Once you have determined the potential cause behind an AC unit not turning on, the next step involves troubleshooting and correcting the issue. Depending on the cause, you may be able to resolve the problem yourself.
### Check the Breaker and Power Source
If the AC unit suddenly turns off, the cause might be a tripped breaker or a missing power switch. Check the breaker to ensure it hasn’t been tripped, and check that the power switch is in the “On” position.
### Clean Supply & Return Lines
If the supply and return lines of the air conditioner are clogged with dirt and debris, the system won’t turn on. In most cases, this can be remedied by using a vacuum cleaner or air compressor to clear any blockages or debris.
### Check for Refrigerant Leaks
If your AC system has lost its charge due to refrigerant leaks, you will need to evaluate the system and its components to determine where the leak may be located. If the leak is small, it may be possible to repair it without needing to replace any parts.
### Check Condenser Unit
For systems where the compressor does not start, check the condenser unit to ensure that it is functioning correctly. Make sure that the motor is securely connected and that the fan is free of any debris.
## Advice & Things to Consider
No matter what type of issue you are facing with your AC, it is always best to get it checked and serviced by a professional before attempting to fix the issue yourself. A qualified technician will be able to accurately evaluate the system, diagnose the issue, and provide the appropriate solutions. Furthermore, they will also be able to recommend the right parts and equipment to properly repair the issue.
