AC Compressor Not Working: Common Coastal Causes and Safe First Checks

As temperatures start to rise, you don’t want to have an AC compressor not working on the Oregon Coast. The good news is that the same symptoms may be due to an easier repair. By reaching out to our heating, ventilation, and air conditioning (HVAC) team for help, you can get professional diagnostics for common coastal issues.

Why is my AC compressor not working? To find out if your compressor is the underlying problem and your options for AC repairs in Bandon, read on.

Signs It Is the Compressor, the Fan Motor, or the Capacitor

Before you can get AC repairs, you first have to find out what’s wrong with your unit. As a general rule, you’ll notice the following symptom patterns for compressor, fan motor, and capacitor malfunctions.

• Compressor: A faulty compressor will likely be silent or fail to start. You may notice warm airflow and repeated tripped breakers. The system may also shut down unexpectedly.
• Fan: When the fan motor malfunctions, you may notice burning odors and rattling sounds. The fan may also stop spinning.
• Capacitor: If you have a compressor humming and not starting, it is likely due to the capacitor not providing the necessary start-up energy.

The Most Common Coastal Causes of Compressor Failure

From finding a condenser dead to having a salt-corroded contactor, coastal conditions cause added strain for your AC. If you’re wondering, “Why is my AC compressor not working?”, the following are some of the major causes of coastal compressor failures that may be at fault.

Pitted Contactor Points

In our coastal environment, salt air and humidity lead to contactor rust and pitting.

Failed Capacitor

Similarly, our climate can result in your coastal AC capacitor failure. This can look like a full compressor failure, which is why professional diagnostics are so important.

Thermal Overload From Fouled Coils

The accumulation of salt, sand, and moisture can cause fouled coils. Because these coils work less effectively, this leads to high refrigerant pressure and overheating. In turn, this added strain can cause the compressor to fail.

Refrigerant Loss From Corrosion-Related Leaks

Corrosion can cause refrigerant to leak out. This forces your compressor to work harder in order to circulate the refrigerant.

Actual Winding Failure

Due to the salty sea air, moisture can lead to electrical shorts and corrosion. All of these problems can result in premature winding failure.

Safe Checks To Make Before Calling

Before you call for professional compressor troubleshooting in Bandon, there are a few safe checks you can perform first.

• Reset the Breaker Once: Try resetting the breaker. However, you should only do this once. Recurring tripped breakers indicate an underlying electrical problem that should be resolved by a professional.
• Check the Disconnect: Make sure the safety switch near your outdoor unit is in the “on” position. There should not be visible signs of damage, such as rust, signs of burning, or melted plastic.
• Look for Visible Corrosion and Debris: Clogged units and corrosion-related damage can cause AC performance problems.

When To Stop and Call a Professional Technician

You should immediately shut off your AC and call for help if you notice the following symptoms.

• Burning odors
• Oil residue
• Repeated breaker trips

To determine the problem, our NATE-certified technicians will check your line voltage, capacitor performance, contactor performance, and winding resistance. The results of these tests will tell us if you need a new AC compressor or a different repair.
