A malfunctioning AC compressor can be a frustrating problem, particularly in warm weather. If your air conditioner’s fan is running but it’s not cooling the air, it’s often an indication that the compressor isn’t working as it should. Several factors can contribute to this issue, ranging from electrical problems to issues with refrigerant levels. This article will explore the most common causes of this issue and how to fix it by getting your Riyadh AC repair services. If you want to repair your AC then you have to contact with us.
1. Faulty Capacitor
A common culprit for a compressor not turning on is a faulty capacitor. The capacitor plays a crucial role in supplying the initial power required to start both the compressor and the fan motor. If the capacitor malfunctions, it can prevent the compressor from receiving the voltage needed to operate. Symptoms of a bad capacitor include Humming sounds. The compressor attempted to start but failed. The AC unit blowing warm air.
Solution: To fix a bad capacitor, it will need to be replaced. Always ensure that the power is turned off before replacing the capacitor, and consult a professional if you’re unsure how to safely handle this repair.
2. Low Refrigerant Levels
If your AC compressor isn’t turning on, it may be caused by a refrigerant leak, leading to insufficient refrigerant levels. Without the proper amount of Refrigerant, the compressor can’t function effectively. The compressor relies on sufficient Refrigerant to maintain cooling. When levels drop too low, the system will fail to operate efficiently or even turn on at all.
Solution: A licensed HVAC technician can inspect the system for leaks and recharge the Refrigerant to the correct level. In some cases, a leak repair may be necessary before the Refrigerant can be recharged.
Faulty Thermostat
If the thermostat isn’t functioning correctly, it may fail to signal the compressor to turn on. In some cases, the thermostat may read incorrect temperatures, causing the compressor to stay off even when the AC is needed.
Solution: Verify that the thermostat settings are correct. If the thermostat is not functioning properly, it may require recalibration or replacement. A professional technician can help troubleshoot and fix thermostat issues.
Compressor Motor Issues
With time, the compressor motor can degrade due to age or excessive use, causing it to have difficulty starting or operating correctly. If the compressor motor struggles to start or makes a loud humming noise, this could indicate a motor failure.
Solution: If the motor is defective, it will most likely require replacement. Replacing the compressor motor is a complicated job, so it is best left to an experienced technician.
AC System Overheating
If your AC unit has been running continuously for a long period, the system could overheat, causing the compressor to shut down as a safety measure. This is especially true in units with blocked airflow or dirty components.
Solution: Give the system time to cool down and check for any obvious issues, like dirty filters or blocked vents.
Faulty Contactor or Relay
The contactor is a switch that controls power to the compressor, and the relay helps it turn on and off. If either of these components fails, it could prevent the compressor from operating.
Solution: A technician can test and replace a faulty contactor or relay.
Power Supply Issues
This could be due to a power surge, issues with the power supply line, or a malfunctioning electrical panel.
Solution: Ensure that your unit is properly plugged in, and check for any visible power issues.
When to Call a Professional
If your AC compressor is not turning on, and you’ve gone through the basic troubleshooting steps, it’s time to call a certified HVAC professional. Complicated issues like electrical malfunctions, refrigerant leaks, or compressor motor failures typically need professional attention.
Conclusion
A malfunctioning AC compressor can be caused by various factors, including a bad capacitor, low refrigerant levels, electrical issues, or even a dirty condenser coil. However, for more serious problems or if you’re unsure about any of the repairs, it’s always best to contact a professional to ensure the issue is properly addressed and avoid further damage to your unit.
