Common Causes of AC Blower Fan Failure

Common Causes of AC Blower Fan Failure

Most homeowners do not have a good understanding of how their HVAC system works, and it isn’t something that you need to be aware of in detail either. You want the system to work correctly and cool your home during the summer months. This is where you need the services of a proven HVAC contractor in San Antonio.

We at Air Texas are here to handle all your air-conditioning installation, maintenance and repair requirements. However, it is always a good idea to have some basic understanding of the system and what can go wrong with it. Here we are going to talk about the fan motor, which is a crucial component of your air conditioning unit.  

 What Is A Fan Motor In Your Hair Conditioning Unit?

This is a simple yet crucial component of any air conditioning system. It is part of the system that pumps air to your unit. Without this air circulation, the AC will not cool your home. Because the fan motor is a very hard-working part, it experiences significant wear and tear, which can result in frequent replacement or repair. If the fan motor breaks down, your air conditioning system will stop blowing cold air; this is something you do not want to deal with during the summer months. 

Signs That Your AC Fan Motor Is Failing

  1. You find that the fan doesn’t start even when you switch on the air conditioner

This is a clear indication that the fan motor is faulty. If the AC runs without its fan circulating, that can cause freezing of the evaporator coils, which can cause severe damage to your system. At this point, you need to switch off the system and call in a San Antonio HVAC technician. 

  1. The fan continues to operate even after you have shut off the air conditioner

This is another common problem caused by a malfunction in the thermostat. The technicians will replace the thermostat to get the system up and running. If the thermostat is not at fault, the technician will check whether the relay switch might be the issue.

  1. The fan is functioning however it is rotating slower than usual

If the blades are not moving as fast as they should, the fan will end up generating a very weak airflow which indicates a failing capacitor or that the bearings have to be oiled.

  1. The fan runs erratically

This could mean one of two things. Either the motor is heating which is causing a cutout, or there could be a loose connection or wire, and the technician will determine what is causing the problem.

If you notice any of these problems in your HVAC system or if you hear a buzzing or rattling sound emerging from the condenser unit when you switch it on, call local experienced HVAC contractors in San Antonio without delay.
