An air conditioner compressor drawing high Rated Load Amps (RLA) can be a cause for concern and might lead to potential issues if not addressed promptly. The RLA is the maximum current that the compressor is designed to draw under normal operating conditions.
Here are some reasons why a compressor drawing high RLA can be problematic:
Overheating: A compressor that draws high RLA may be working harder than it should, leading to increased heat generation. Over time, this can cause the compressor to overheat, which may result in premature wear and tear or even compressor failure.
Reduced Efficiency: High RLA indicates that the compressor is consuming more electricity to operate. This can lead to decreased overall efficiency, resulting in higher energy bills and increased strain on other components of the air conditioning system.
Compressor Stress: A compressor operating at high RLA is under increased stress, potentially leading to accelerated wear on its mechanical components. This stress can cause parts to wear out faster, shortening the compressor's lifespan.
Potential System Shutdown: Many air conditioning systems have built-in safety mechanisms that can shut down the system if the compressor draws excessively high current. This is done to protect the unit from damage, but it can leave you without cooling until the issue is resolved.
Several factors can contribute to a compressor drawing high RLA, such as:
Refrigerant Leaks: Low refrigerant levels can cause the compressor to work harder to maintain the desired cooling, leading to higher RLA.
Dirty Condenser or Evaporator Coils: Dirt and debris on the coils reduce heat exchange efficiency, forcing the compressor to work harder to achieve the desired cooling effect.
Blocked Airflow: Obstructions to the airflow, such as a clogged air filter or blocked vents, can cause the compressor to draw higher current.
Mechanical Issues: Internal mechanical problems within the compressor can also lead to increased RLA.
If your air conditioner's compressor is consistently drawing high RLA, it's essential to have it inspected and repaired by a qualified HVAC technician. They can diagnose the root cause of the issue and perform the necessary repairs or maintenance to prevent further problems and ensure the air conditioning system operates efficiently and reliably.
