How to Know If Your AC Compressor is Working?

To tell if your ac compressor is running, check if the compressor clutch engages and listen for a humming noise. The compressor clutch should spin with the pulley when the ac is turned on, and the humming noise indicates that the compressor motor is running.

Air conditioning is a necessity, especially during hot summer months. However, a malfunctioning ac system can cause a lot of discomforts. If you feel that your ac isn’t cooling your home, it could be due to a faulty compressor. The compressor is responsible for transferring the refrigerant gas from the evaporator to the condenser coil, where it cools down.

Therefore, it’s essential to keep the compressor in good working condition, and the first step is to confirm whether it is running or not. In this article, we will guide you on how to tell if ac compressor is running to help you diagnose the problem quickly.

There are three ways to test if your ac compressor is running: checking the ac clutch, listening for unusual sounds, and using a manifold gauge set to measure pressure.


Common Causes Of Ac Compressor Failure

The ac compressor is an essential component of your air conditioning system, and if it’s not running, your ac won’t cool your home. Common causes of ac compressor failure include electric faults, refrigerant leaks, clogged orifice tubes, and blocked condensers.

Electric faults occur due to damaged wiring, blown fuses, or broken relays. Refrigerant leaks can result from corroded lines or seals, while clogged orifice tubes can restrict the flow of refrigerant, causing the compressor to work harder and eventually fail.

Finally, a blocked condenser can prevent heat transfer, leading to overheating and compressor failure. If you suspect your ac compressor is not running, it’s best to contact a professional hvac technician to diagnose and fix the issue.

Steps To Fix A Faulty Ac Compressor

One way to determine if your ac compressor is functioning properly is to listen for a humming sound. If you don’t hear anything, check the electrical system for faulty wiring or a blown fuse. Recharging the refrigerant may also be necessary if it is low.

If these steps don’t work, replacing the compressor might be required. Before installing a new compressor, flush out the entire ac system to ensure it is clean. It’s crucial to remember that working with air conditioning systems can be dangerous, so seeking the help of a professional is recommended if you are unsure of what to do.
