An air conditioning unit can be considered a “best friend” in the scorching summer heat as it keeps the abode airy and odor-free. But what if the system malfunctions? Especially when the compressor doesn’t go ahead? Your AC compressor is a significant part of the cooling equipment, and if the compressor does not work, the whole system will not cool your house. You don’t have to worry! In the following guide, we will explain what an air conditioner compressor is, why air conditioner compressor not turning on, and how you can get it fixed. We have comprehensive information on everything you need to know, whether you are a novice or simply want to be enlightened about your AC system. Let’s begin!
What is an Air Conditioner Compressor?
The compressor is the main component of your AC system, likely running very hot, so you will want it to be running well. It must take place for the cooling process to happen. This is why compressor problem troubleshooting is so important!
Why Your Air Conditioner Compressor Not Turning On
Power Supply Problems
If the compressor won’t turn on, the power supply is the first thing to look into. At times, the circuit breaker is tripped which results in your AC system having its power supply cut off. You may be able to fix the problem by resetting the breaker. You should also check for loose or damaged wires that may be broken off from the power.
Thermostat Issues
The air conditioner is controlled by the master (regulator) of the thermostat. If set improperly, it may also run the motor too fast or slow so that the compressor will not start. This may seem elementary, however, check that the thermostat is turned up to “Cool” and that the temperature settings are lower than the ambient room temperature. It may also be found that the batteries that are mounted need replacing. In addition to that, this is not complicated at all and cannot be done just by changing them to new ones or by getting a new digital program thermostat.
Faulty Capacitor
The capacitor is an outstanding product that enables the compressor to start with the additional energy it needs. If it is broken, the compressor cannot run. In this case, the capacitor can seem swollen or even leaking. A professional can perform this task. Nonetheless, it is a typical repair.
Overheating
Overheating can happen if there is not enough airflow, and it will result in the shutting down of your compressor which will further protect itself. When the outdoor unit is dirty or there is no airflow around it, it may be the occurrence of this problem. Cleaning the unit and clearing off the area are the things that can keep the unit from overheating.
Refrigerant Problems
Refrigerant is the only thing that cools your home. The problem is that the cooling compressor will not work due to low refrigerant levels or leaks. Symptoms of a refrigerant problem include ice on the coils, a hissing noise, or inadequate cooling. The problem of refrigerant is something you’re better off having a professional deal with, as the solution may be too dicey for you to attempt on your own.
Electrical Failures
An air conditioner has relays, contactors, and wires, which are like a path that carries the electricity from the compressor. If these parts fail, the compressor will not start. To check electrical problems, a licensed technician is trained to do so, and that is the best option.
Compressor Failure
If something is wrong with the AC that is causing it to not pump out cold air, it could be the compressor. This is a critical matter because the replacement of the compressor can be quite costly. If your compressor is not generating any noise or vibration, there could be a high chance it is no longer functioning. If you’re unsure, a technician can guide you on whether to go for repair or buy another unit.

Step-by-Step Troubleshooting Guide
Step 1: Check the Power
Inspect your circuit breaker and reset it if it’s tripped. Make sure the AC unit is plugged in properly. If you find damaged wires, call a professional electrician to fix them.
Step 2: Adjust the Thermostat
Set your thermostat to “Cool” and lower the temperature. If the thermostat doesn’t respond, try changing the batteries or upgrading to a new model.
Step 3: Clean the Outdoor Unit
Turn off the power and remove any dirt, leaves, or debris from the outdoor unit. Use a hose to clean the coils gently. This improves airflow and prevents overheating.
Step 4: Inspect the Capacitor
Look at the capacitor for signs of damage like swelling or leaks. If it looks faulty, you’ll need a professional to replace it.
Step 5: Look for Refrigerant Leaks
If you see frost on the coils or hear a hissing sound, there might be a refrigerant leak. Only a licensed technician should handle refrigerant repairs.
Step 6: Call a Professional
If you’ve tried all these steps and the compressor still won’t turn on, it’s time to call an HVAC technician. They can diagnose complex issues and recommend the best solution.
Preventive Maintenance Tips for Your AC System
Keeping your AC system in good shape can prevent compressor problems in the future. Here are some tips:
- Schedule Regular Servicing: Have a professional inspect and clean your AC system at least once a year.
- Replace Filters: Dirty filters block airflow, making the compressor work harder. Replace them every 1-3 months.
- Keep the Outdoor Unit Clear: Remove leaves, dirt, and debris from around the unit to ensure proper airflow.
- Monitor Refrigerant Levels: Ask your technician to check the refrigerant during maintenance visits.
