Air conditioner compressor may keep running when turned off due to a faulty thermostat, capacitor issues, or refrigerant problems. It's essential to consult a professional to diagnose and resolve the issue for efficient cooling and energy conservation.
Experiencing the perplexing issue of your air conditioner compressor persistently running even after being turned off? If the hum of your AC unit has left you scratching your head, you're not alone. In this guide tailored for beginners, we'll unravel the mysteries behind this common problem and provide simple, actionable solutions to bring relief to both your overheated home and your puzzled mind. Stay cool as we navigate the troubleshooting steps and shed light on what might be causing your AC compressor to defy the off switch.
If your air conditioner compressor keeps running when you turn it off, the compressor is likely overloaded. You'll need to reduce the load on the compressor by either reducing the number of appliances turned on at once or reducing the size of your living space. If you cannot reduce the compressor load, you may need to have it serviced.

Causes of an air conditioner compressor that keeps running
There are a few reasons your air conditioner compressor may keep running when you turn it off. Here I'll explore seven potential causes of this problem.
1. Improperly Sized Unit
If your AC unit is too small, it will have to work harder to cool your home, which will cause the compressor to run more often. On the other hand, if your unit is too large, it will cool your home too quickly and turn off before the humidity can be removed from the air, which will also cause the compressor to run more often.
2. Dirty Air Filters
If your air filters are dirty, the airflow to your AC unit will be restricted. This will cause your unit to work harder to cool your home, which will make the compressor run more often.
3. Dirty Condenser Coils
If the condenser coils on your AC unit are dirty, the unit will have to work harder to cool your home, which will cause the compressor to run more often.
4. Refrigerant Leaks
If there is a leak in your AC unit's refrigerant line, the unit will not be able to cool your home properly. This will cause the compressor to run more often to compensate for the lack of coolant.
5. Thermostat Issues
If your AC unit's thermostat is not set properly, the unit will not be able to cool your home properly. This will cause the compressor to run more often to compensate for the incorrect temperature setting.
6. Incorrectly Wired AC Unit
If your AC unit is wired incorrectly, it will not be able to function properly. This will cause the compressor to run more often to cool your home, but the unit will not be able to do so correctly.
7. Fan Issues
If the fan in your AC unit is not working properly, the unit will not be able to cool your home properly. This will cause the compressor to run more often to compensate for the lack of airflow.
How to troubleshoot and fix an air conditioner compressor that keeps running when turned off
If your air conditioner compressor keeps running when turned off, there could be a few different reasons. In this article, we'll go over seven possible solutions to this problem so that you can get your AC unit up and running again in no time.
1. Check the thermostat settings.
One of the most common reasons an air conditioner compressor will keep running when it's turned off is incorrect thermostat settings. For example, if the thermostat is set to "On," the compressor will continue to run even when the AC unit is turned off. To fix this, simply change the setting on the thermostat to "Off."
2. Check the air filter.
Another possible reason your air conditioner compressor keeps running when it's turned off is that the air filter is dirty. A dirty air filter can cause the compressor to overheat, which will cause it to keep running even when the AC unit is turned off. To fix this, simply clean or replace the air filter.
3. Check the evaporator coils.
Another possible reason your air conditioner compressor keeps running when it's turned off is that the evaporator coils are dirty. Dirty evaporator coils can cause the compressor to overheat, which will cause it to keep running even when the AC unit is turned off. To fix this, simply clean the evaporator coils.
4. Check the condenser coils.
Another possible reason your air conditioner compressor keeps running when turned off is that the condenser coils are dirty. Dirty condenser coils can cause the compressor to overheat, which will cause it to keep running even when the AC unit is turned off. To fix this, simply clean the condenser coils.
5. Check the outdoor unit.
Another possible reason your air conditioner compressor keeps running when it's turned off is that the outdoor unit is dirty. Dirty outdoor units can cause the compressor to overheat, which will cause it to keep running even when the AC unit is turned off. To fix this, simply clean the outdoor unit.
6. Check for leaks.
Another possible reason your air conditioner compressor keeps running when it's turned off is that there are leaks in the system. Leaks can cause the compressor to overheat, which will cause it to keep running even when the AC unit is turned off. To fix this, simply repair any leaks.
7. Check the voltage.
Another possible reason your air conditioner compressor keeps running when it's turned off is incorrect voltage. If the voltage is too low, the compressor will overheat, which will cause it to keep running even when the AC unit is turned off. To fix this, check the voltage and ensure it is correct.
If your air conditioner compressor keeps running when turned off, there could be a few different reasons. In this article, we've gone over seven possible solutions to this problem. Try one of these solutions and see if it fixes the problem. If not, try another solution until you find one that works.
Preventative maintenance tips for keeping your air conditioner compressor in good working order
An air conditioner compressor is a vital part of the air conditioning system in your home. The compressor is responsible for circulating the refrigerant throughout the system. A well-maintained air conditioner compressor will last many years, but if it is not properly cared for, it can break down prematurely.
Here are ten tips for preventative maintenance of your air conditioner compressor:
- Check and clean the air filter regularly. The air filter protects the compressor from dust and debris. If the air filter is dirty, it can restrict airflow and cause the compressor to overheat.
- Keep the area around the air conditioner compressor clear of debris. Debris can block airflow and cause the compressor to overheat.
- Inspect the air conditioner compressor for signs of wear and tear. If the compressor is damaged, it can leak refrigerant and cause the system to fail.
- Lubricate the air conditioner compressor regularly. This will help keep the compressor running smoothly and reduce wear and tear.
- Check the electrical connections to the air conditioner compressor. Loose or damaged wires can cause the compressor to overheat or fail.
- Inspect the air conditioner compressor for leaks. Leaks can allow refrigerant to escape, which can cause the system to fail.
- Test the air conditioner compressor regularly. This will help to ensure that the compressor is working properly and can prevent problems before they occur.
- Replace the air conditioner compressor if it is not working properly. A damaged or defective compressor can cause the entire system to fail.
- Have a qualified technician service the air conditioner compressor regularly. This will help keep the compressor in good working order and prevent problems before they occur.
- Follow the manufacturer's recommendations for the air conditioner compressor preventative maintenance. These recommendations will help ensure the compressor is properly maintained and can last for many years.
