Car Ac Compressor Not Working But Fan is Running

Last Updated on June 24, 2023 by Ryan

If the AC compressor is not working but the fan is running, then it is likely that there is an issue with the system’s electrical circuit. This could be caused by a faulty relay or a blown fuse. It could also be due to a wiring issue such as a loose connection or short in one of the wires leading to and from the compressor.

If nothing appears visibly wrong, then it may be necessary to use an ohmmeter to check for continuity in order to locate any issues with connections between components of the system. Lastly, if all else fails, consulting with an experienced HVAC technician would be recommended in order to find and fix whatever problem exists within your car’s AC compressor system.

If you’ve noticed that your car’s AC compressor is not working but the fan is running, it could be a sign that something more serious is going on. The compressor plays an important role in cooling the air and circulating it through your vehicle, so if it isn’t functioning properly, this can lead to uncomfortable driving conditions and even safety hazards. It’s best to have a professional take a look at your system as soon as possible so they can diagnose the issue and make any necessary repairs.

Why Does My Ac Fan Come on But Not the Compressor?

If your AC fan is running but the compressor isn’t, it could indicate an issue with the unit’s electrical system. The most common cause of this type of problem is a faulty capacitor or contactor. The capacitor helps start and run the compressor, while the contactor controls power to the fan and compressor.

If either of these components fail, then neither will get enough electricity to operate properly. Other potential causes include a blown fuse in your AC’s outdoor unit, loose wires on the circuit board, or even a bad thermostat setting. If you are unsure how to fix any of these issues yourself, it is best to call an HVAC technician for assistance as they have specialized tools and knowledge needed for proper diagnosis and repair.

Why is My Ac Compressor Fan Spinning But Not Cooling?

It is possible that a few different issues could be causing your AC compressor fan to spin without cooling. The most common cause is inadequate refrigerant levels; if the coolant level in the system has fallen due to a leak or other problem, the fan will run but won’t cool because there isn’t enough refrigerant left in the system to absorb heat and transfer it outside. Other potential causes include problems with internal components such as an electrical issue, a bad capacitor, or a faulty thermostat.

In some cases, clogged air filters may also prevent proper airflow and reduce cooling efficiency. If you’re having difficulty pinpointing the issue yourself, it’s best to call an HVAC technician for help diagnosing and repairing your AC unit so you can get back up and running quickly!

Will an Ac Fan Work If the Compressor is Bad?

No, an air conditioning fan will not work if the compressor is bad. The compressor is responsible for compressing and circulating refrigerant throughout the system, which creates a cooling effect by absorbing heat from inside the home. Without a working compressor, there is no way to circulate this cooled refrigerant through the system and therefore the AC fan will not be able to generate any cooling effects.

What Causes an Ac Compressor to Stop Working in a Car?

A car AC compressor is one of the most important components in an air conditioning system. It is responsible for pressurizing and compressing the refrigerant that circulates through the AC system, cooling your vehicle’s interior. When a car AC compressor stops working, it can be due to a variety of reasons ranging from mechanical issues such as worn out internal parts or seals, to electrical problems like bad fuses or wiring.

Compressors may also fail if they become clogged with dirt and debris buildup or experience extreme temperature changes. In some cases, low levels of Freon can cause an AC compressor to stop working as well; this should always be checked first when troubleshooting any issue with your car’s air conditioning system.

Ac Unit Not Working But Fan Blowing

If your air conditioner is not working, but the fan is blowing, it could be due to a number of factors. The most common cause is an issue with the compressor or condenser; if these components have failed, then they may need to be replaced in order to restore function to your AC unit. Additionally, electrical issues such as blown fuses or tripped breakers can also cause this problem.

If you suspect either of these causes, contact an HVAC technician for assistance and repairs.

Window Ac Compressor Not Working But Fan is Running

If your window AC unit’s compressor is not running but the fan is, it could be due to a few different things. It may be caused by an electrical issue such as a blown fuse or tripped circuit breaker, a defective thermostat, or even an issue with the motor itself. If you suspect that any of these are causing your problem, it’s best to contact a professional HVAC technician for assistance.

Can Ac Capacitor Run Fan But Not Compressor

Yes, an AC capacitor can run a fan motor but not a compressor. The ac capacitor helps the fan motor start up and keep running by providing it with the necessary power to rotate the blades. At startup, the capacitor supplies extra current that is needed for the initial push of power to get the fan going.

However, due to its low voltage output, an AC capacitor cannot provide enough energy to start or keep a compressor running.


In conclusion, it is important to note that when a car air conditioning compressor is not working but the fan is running, then the issue could be due to several different factors. This can include problems with the electrical components, wiring issues, leaks in the system and more. If you think your car A/C compressor may have an issue it’s best to take it to a professional who can diagnose and repair any potential problems quickly and safely.
