Is your Frigidaire air conditioner not cooling your home like it used to? One common reason could be that the compressor isn’t turning on.
Without the compressor running, your AC can’t push cool air, leaving you stuck in the heat. If you’ve noticed your unit humming but no cold air, or it won’t start at all, you’re probably wondering what’s wrong and how to fix it.
Keep reading, because understanding why your Frigidaire air conditioner compressor isn’t turning on can save you time, money, and frustration. Let’s dive into the most common causes and what you can do about them.
Common Causes Of Compressor Failure
The compressor is the heart of your Frigidaire air conditioner. It pumps refrigerant through the system to cool your home. When the compressor fails to start, the whole unit stops working. Understanding the common causes of compressor failure helps you spot problems early. This can save you time and money on repairs.
Power Supply Issues
Power problems are a common cause of compressor failure. A tripped circuit breaker or blown fuse can cut off electricity. Loose or damaged wiring also stops the compressor from running. Check your power source and electrical connections first.
Thermostat Problems
The thermostat controls when the compressor turns on. A faulty or miscalibrated thermostat may not send the right signal. This can prevent the compressor from starting. Test or replace the thermostat if it shows wrong temperatures.
Capacitor Failure
The capacitor helps the compressor start and run smoothly. When it fails, the compressor struggles to turn on. You may hear a humming noise or no noise at all. Replacing a bad capacitor often fixes the problem.
Refrigerant Leaks
Low refrigerant levels cause the compressor to overheat. Leaks reduce the cooling power and stress the compressor. Look for oily spots or hissing sounds near pipes. Fix leaks and recharge refrigerant to protect the compressor.
Contactor Malfunctions
The contactor sends power to the compressor motor. If it sticks or burns out, power cannot reach the compressor. This stops it from starting. Inspect the contactor for signs of damage or wear and replace if needed.

Diagnosing Compressor Issues
Diagnosing issues with your Frigidaire air conditioner compressor can save time and money. The compressor is key for cooling your home. If it doesn’t start, the whole system fails. Simple checks can reveal common problems. Follow these steps to find the cause.
Checking Electrical Connections
Start by examining the electrical connections. Loose or damaged wires can stop the compressor from working. Turn off power to the unit before checking. Look for burnt wires or corrosion on terminals. Tighten any loose connections carefully. Faulty wiring often causes compressor failure.
Testing The Capacitor
The capacitor helps the compressor start and run smoothly. A bad capacitor can prevent the compressor from turning on. Use a multimeter to test its electrical charge. If the reading is low or zero, the capacitor needs replacement. This small part often causes big problems.
Inspecting The Thermostat
The thermostat controls the temperature setting. A broken thermostat may not send the signal to start the compressor. Check if the thermostat is set correctly. Replace batteries if it uses any. Test the unit by adjusting the temperature to see if the compressor responds.
Measuring Refrigerant Levels
Refrigerant cools the air inside your home. Low refrigerant levels can stop the compressor from working. Use a gauge to measure the refrigerant pressure. Leaks cause low levels and can harm the compressor. Call a professional if the refrigerant is low or leaking.
Quick Fixes To Try At Home
When your Frigidaire air conditioner compressor won’t start, some fixes might help. These simple steps can save time and money. Try these at home before calling a technician. They are easy to do and often solve the problem quickly.
Resetting The Circuit Breaker
Check the circuit breaker panel first. The breaker may have tripped. Flip the switch off and then on again. This can restore power to the compressor. Sometimes, a reset fixes electrical glitches.
Replacing The Capacitor
The capacitor helps start the compressor motor. A faulty capacitor stops the compressor from running. You can test it with a multimeter. Replace it if it shows no charge. This part is inexpensive and easy to swap out.
Cleaning The Condenser Coils
Dirty coils block airflow and strain the compressor. Turn off the unit and clean the coils gently. Use a soft brush or garden hose. Clear coils improve cooling and help the compressor work better.
Adjusting The Thermostat Settings
Check if the thermostat is set too high. Lower the temperature setting to start cooling. Make sure the thermostat is on “cool” mode. Sometimes, a simple setting change gets the compressor running again.
When To Call A Professional
Knowing when to call a professional for your Frigidaire air conditioner compressor saves time and prevents damage. Some problems need expert tools and skills. Trying to fix these issues alone can be risky and may cause more harm.
Handling Refrigerant Safely
Refrigerant is a key part of your air conditioner. It cools the air by moving heat outside. Handling refrigerant requires special training. It is harmful to breathe and damages the environment. Professionals have the right equipment to manage refrigerant safely. Do not try to refill or fix leaks yourself.
Complex Electrical Repairs
Electrical parts control the compressor’s power. Problems like broken wires or faulty capacitors need expert attention. Working with electricity can cause shocks or fires. A professional knows how to test and fix electrical issues correctly. Leave electrical repairs to trained technicians to avoid injury and damage.
Compressor Replacement
The compressor is the heart of your air conditioner. If it stops working, it might need replacement. This job is heavy and requires special tools. Removing and installing a compressor involves careful handling of parts and fluids. A professional can replace it safely and ensure the system works well again.
Preventive Maintenance Tips
Preventive maintenance keeps your Frigidaire air conditioner running smoothly. It helps avoid compressor issues before they start. Regular care extends the life of your unit and saves money on repairs.
Regular Cleaning Schedule
Clean the air filters every month. Dust and dirt block airflow and strain the compressor. Wipe down the exterior and remove debris near the unit. Clean coils at least twice a year to improve cooling.
Seasonal Inspections
Check the system before summer and winter seasons. Look for signs of wear or damage on wires and parts. Tighten loose connections and replace worn components. Testing the compressor early prevents sudden failures.
Monitoring System Performance
Listen for unusual noises or vibrations. Monitor cooling efficiency and energy use regularly. Notice any changes in temperature or airflow. Early detection of problems helps keep the compressor working well.
