AC problems cause headaches for home and business owners. One common problem with air conditioners is the fan motor. Knowing the causes of fan motor failure and the signs it is failing is critical. Prompt repairs will get the air conditioner up and running again and ensure the motor works effectively so further breakdowns are less likely to occur. 

Signs an AC Fan Motor Is Failing

When it comes to AC and heater repairs, learning about the signs of problems helps owners take prompt action. Owners who notice the following signs need to call for immediate repair. Technicians will check the AC fan motor to determine if it can be repaired or needs replacing. 

· The fan will not start even though the air conditioner is on. When the fan will not start, there is often a fault in the motor. Air cannot circulate when the fan will not turn. The air conditioner will not function without the motor.

· Motor problems can also occur when the fan continues to run even though the air conditioner has been shut off. Owners should never ignore a constantly running fan because it can signal significant problems with the motor. 

· The fan may only rotate very slowly. Fans need high velocity to circulate cool air throughout the home. If the fan is barely turning, this is a sign the motor is failing. Often, this is a sign the motor bearings are failing and need replacing. 

· The fan may also run intermittently. Sometimes the motor performs, and other times it refuses to come on. Intermittent fan issues require a professional diagnosis to find the cause. Technicians will discover if the fan motor needs repair or replacement. 

· A buzzing sound occurs when the fan is turned on, but the fan does not respond. The buzzing sound sometimes indicates an overheating motor. Call a technician to find the problem and correct it for improved function. 

What Causes AC Fan Motors to Stop Working?

There are many reasons air conditioner fan motors may stop working. Understanding the reasons will help owners know when to seek professional repairs. 

· Power issues are common and will cause an AC fan motor to stop working abruptly. When the air conditioner system starts overheating, it may trip a breaker and prevent the fan from working. Always check the power supply before proceeding further. 

· Capacitors can malfunction and cause a fan motor to stop working as it should. Capacitor failures are one of the top reasons fan blades do not spin. A technician can check the capacitor and determine if it needs a replacement. 

· The compressor contractor can also go bad and cause motor failure. The compressor contractor sends the electrical signal to the fan so it starts working. These can wear out over time and need a replacement. 

· The AC motor can also burn out. These motors will last 10 to 15 years before going out. Once they burn out, they need a replacement so the fan can begin working again. 

Seek Professional Repairs

Owners should not take a DIY approach to AC repair. There are many complicated parts. Those without the proper knowledge and tools could find themselves with a problem. Call professional HVAC technicians, and they can come out and diagnose and repair the fan motor issue without delay.
