When the AC compressor starts, but suddenly shuts off after just a few seconds, it might be one of the most aggravating issues with your air conditioning system.
Numerous things, from straightforward electrical difficulties to more complicated problems with the compressor or refrigerant levels, can contribute to this problem. In this post, we’ll look more closely at some of the typical reasons of this ac compressor starts then shuts off and offer some solutions.
What Causes Your AC Compressor to Start and Then Shut Off?
There are several reasons why your AC compressor might start and then shut off:
- Electrical problems: If there is an issue with the electrical system in your air conditioning unit, it could cause the compressor to start and then shut off. This could be due to a faulty capacitor, a blown fuse, or a problem with the wiring.
- Low refrigerant levels: The refrigerant in your AC system plays a critical role in cooling your home. If the refrigerant levels are low, it can cause the compressor to start and then shut off. This could be due to a leak in the system or a problem with the compressor itself.
- Blocked air flow: If the air flow in your air conditioning system is blocked, it can cause the compressor to start and then shut off. This could be due to a clogged air filter, blocked vents, or a problem with the blower motor.
- Dirty condenser coils: The condenser coils in your air conditioning unit help to release the heat that is absorbed by the refrigerant. If these coils are dirty or blocked, it can cause the compressor to start and then shut off.

How to Fix Your AC Compressor That Starts and Then Shuts Off?
The first step in fixing your AC compressor that starts and then shuts off is to identify the underlying cause of the problem. Here are some steps you can take:
- Check the electrical system: Make sure that the electrical system in your air conditioning unit is working properly. Check the capacitor, fuses, and wiring to make sure that everything is in good condition.
- Check the refrigerant levels: If your AC system is low on refrigerant, it could be due to a leak or a problem with the compressor. You will need to have a professional HVAC technician diagnose and fix the problem.
- Check the air flow: Make sure that the air flow in your air conditioning system is not blocked. Check the air filter, vents, and blower motor to make sure that everything is working properly.
- Clean the condenser coils: If the condenser coils are dirty or blocked, it can cause the compressor to start and then shut off. Use a soft brush or compressed air to clean the coils and improve the flow of air.
Electrical issues, low refrigerant levels, obstructed airflow, or filthy condenser coils are just a few of the potential causes of your AC compressor cycling on and off. You must locate the root of the issue and take proper action to resolve it in order to solve it. In some circumstances, you might need to contact a qualified HVAC specialist to identify and resolve the issue.
Your air conditioning system can work more smoothly and efficiently with regular cleaning and maintenance, which can help avoid this issue from ever arising.
