Don't Let A Broken Fan Break Your Air Conditioner

Posted on: 16 August 2022

One of the most important parts of an air conditioner is the fan. This part of your AC blows the air after it has been chilled through the use of refrigerants. If the fan stops working, you'll want to have it repaired as soon as possible because a malfunctioning fan can cause your AC to become damaged. 

Why a Broken Fan Can Kill Your AC

When the fan is not working properly in your AC, this can create issues with airflow. As a result, the compressor might overheat and fail. This can lead to the death of your AC unit. Most AC units will have two fans. One is located on the inside and the other is located on the outside.

The fan that is found inside your home is called the blower and is contained within the air handler unit. The purpose of this fan is to blow cold air into your home. Meanwhile, the outdoor fan exists to circulate air through the outside condenser coils. Unfortunately, when either of these fans stops working, it can be difficult to determine what is causing the defective fan due to how complex an AC unit is.

Replace the Filter

Before contacting a repair technician, make sure that the air filter doesn't simply need to be cleaned or replaced. Some AC air filters are disposable and other AC air filters must be removed and washed. If you do not replace or clean your AC filter, it will become clogged with dirt and will disrupt the airflow of your AC unit.

Repair Broken Fans

The fan itself might have become damaged. For example, the fan might have a broken fan blade. Repairing a broken fan blade can be dangerous especially if the fan turns on while the unit is being repaired. Therefore, you'll never want to perform the repairs yourself and will instead want to hire a repair technician. 

Check the Power Supply

The air conditioning repair technician will try to determine if there are any power supply issues. The fan relies on electricity to remain operational. The repair technician will check the circuit breaker to make sure that it hasn't been tripped. If a fuse is blown, it will need to be replaced by a professional that is experienced with working with your brand of air conditioners.

Look for Other Issues

There are various other problems that can arise such as a frozen condenser coil, a burned-out evaporator, a burned-out motor, or a malfunctioning compressor. Once the technician finds out why the fan isn't working, they'll be able to repair or replace your unit.

Summer is Upon Us – Is Your AC Working?

Hi. My name is Laurie Waters. The HVAC contractor was just out at our house last week and did I ever get a lesson from him. You see, we had a warm spell hit and I went to turn our air conditioning on for the first time since last summer. Much to my dismay, it wasn’t working. All I got was a blast of warm air. The fan was bringing the outdoor heat inside. Thank goodness it wasn’t anything major. My unit needed Freon. While he was here, the contractor taught me how to do some routine maintenance around my unit, vents, and filters. I’m going to share this information with you. I hope you find it to be useful.
