4 Reasons Why AC Compressor Not Working But Fan Is Running

A malfunctioning air conditioner can quickly turn your home into an uncomfortable environment. One common issue homeowners face is when their AC compressor fails to work while the fan continues to run. This can leave you puzzled and seeking answers. In this blog post, we will explore the four main reasons behind this problem and provide you with insights to help you understand what might be causing it. If you are in need of professional AC service in Springboro area, Comfort Solutions Heating/Cooling & Duct Cleaning is here to assist you.

Here Are The Reasons

  • Thermostat Issues
    One of the first things to check when your AC compressor fails to start is the thermostat. The thermostat serves as the control center for your air conditioning system, and if it malfunctions, it can prevent the compressor from turning on. Ensure that the thermostat is set to the cooling mode and at the desired temperature. Additionally, check if the thermostat is receiving power and if the wiring is properly connected. If you’re unsure how to handle thermostat troubleshooting, it’s best to rely on the expertise of professionals, such as Comfort Solutions Heating/Cooling & Duct Cleaning, offering reliable AC repair services in Springboro.

  • Capacitor Problems
    The AC compressor relies on capacitors to start and run efficiently. There are two types of capacitors in an air conditioning system: the start capacitor and the run capacitor. If either of these components fails, it can result in the fan running while the compressor remains idle. Faulty capacitors are a common issue that can be diagnosed and resolved by experienced technicians. If you suspect capacitor problems, it’s crucial to seek professional assistance.

  • Electrical Issues
    Electrical problems can also cause your AC compressor to stop working while the fan continues to run. Faulty wiring, a blown fuse, or a tripped circuit breaker can disrupt the electrical supply to the compressor, leading to its inactivity. These issues require technical knowledge and expertise to identify and resolve. Comfort Solutions Heating/Cooling & Duct Cleaning has a team of skilled technicians who can diagnose electrical problems accurately and offer effective solutions for AC repair in Springboro.

  • Refrigerant Leaks
    Another reason for an AC compressor not working properly is refrigerant leaks. The refrigerant is responsible for cooling the air in your AC system, and when there is a leak, the refrigerant level drops, affecting the compressor’s functionality. A low refrigerant level can trigger safety mechanisms that prevent the compressor from turning on while the fan may continue to operate. Detecting and repairing refrigerant leaks requires specialized tools and knowledge, making it essential to rely on professionals like Comfort Solutions Heating/Cooling & Duct Cleaning to handle the task.


When your AC compressor fails to work while the fan continues to run, it’s crucial to address the issue promptly to avoid further discomfort in the heat of summer.
