Modern air conditioning… it’s a lovely thing on a hot, humid summer day to go inside and experience respite from the heat. That’s why it’s so frustrating to turn on your air conditioner only to discover that the fan isn’t working and the temperature in your home is rising. But before you lose your cool over your HVAC Fan Not Working, take a few minutes to troubleshoot and determine if it’s an issue you can fix yourself or if you need to call your local Bluco HVAC specialist at (929) 447-2077 for professional HVAC repair near me.

HVAC Fan Not Working

Know where to look. A split-system central air conditioner has two fans: one inside and one outside. The furnace or air handler contains a fan, or “blower.” It blows cold air into living spaces and draws return air into the system to be cooled by the evaporator coil. The outdoor unit contains an outdoor fan, sometimes called a condenser fan. It pushes air via outdoor condenser coils to remove home heat. If either of these fans stops working, fix it to prevent significant, costly cooling system problems.

WHY THE CENTRAL AIR CONDITIONING FAN IS NOT WORKING

Before assuming the problem is caused by a faulty fan, spend a few minutes evaluating whether other faults with your air conditioning system may be to blame. Your central air conditioner is a complex system with numerous components, and several difficulties could account for a working AC fan. Here are a few that might apply to your situation:

1. Bad Capacitor

A faulty capacitor is one possible cause for your AC fan to stop working. The capacitor is a little cylinder that gives energy to the motor of your AC machine. It is responsible for starting the air conditioner and delivering additional electricity to keep it running.

 

Indicators of a faulty capacitor include:

 

  • AC not turning on 
  • Air conditioner turning off by itself 
  • System not producing chilly air 
  • Cooling System creates a whirring sound

 

The capacitor can be examined with a screwdriver or a tiny stick. Gently slide the stick between the vents and lightly press the fan blade. If the fan starts and continues to spin on its own, the capacitor is defective.

2. Broken Motor

The condenser fan motor on your air conditioner rotates the fan’s blades to draw outside air across the condenser coils. This process transforms heated refrigerant gas into a cool liquid, ultimately supplying your home with cool air. Fan failure is usually caused by a defective motor, which should be serviced or replaced soon.

3. Frozen Evaporator Coil

Non-working air conditioner fans may indicate a frozen evaporator coil. The evaporator coil is housed within the air handler unit (furnace or fan coil) and removes heat and humidity from the incoming interior air. The evaporator coil may freeze due to a malfunctioning indoor blower fan, insufficient refrigerant charge, low outside temperatures, or other system failures. A frozen evaporator coil may stop a blower fan, so a local Bluco professional should examine and fix it.

4. The Compressor Isn’t Working

Many of the above-discussed faults can ultimately destroy the compressor. The exterior unit’s compressor circulates refrigerant through copper tubing and coils. If your air conditioner is silent yet the power and thermostat are on, it may have a broken compressor. Compressor replacement is a significant task that a professional and experienced HVAC expert should complete. This will certainly raise the question of whether it’s time to replace the entire device or do the necessary repair.

5. Air Filter Is Blocked

A dirty, blocked air filter is another common and simple-to-repair cause of a central air conditioner fan that will not operate. Your system’s air filter captures dust, debris, and other airborne pollutants to maintain cleaner indoor air and cooling system components. A blocked air filter can decrease airflow so much that it seems like the indoor fan isn’t working. In extreme circumstances, reduced airflow can shut down the entire system. If this is the case, the issue should be remedied by cleaning or replacing the air filter.

6. The Breaker Has Tripped

Check the power supply and whether the thermostat is proper. Check three spots to be sure the problem isn’t with the power supply. First, make sure the AC’s main breaker hasn’t tripped. The outside equipment should have its 220v circuit. If that’s not the issue, check the air handler (furnace or fan coil) in your home for a light-looking power switch. If not, verify the outdoor power disconnect. Usually installed near the outside unit in a separate box. Ensure it’s on. In the case that this box’s fuse blows, contact a Bluco contractor.

Consider a power surge as a possible reason for a tripped circuit breaker. If the system continues to trip the circuit breaker, turn it off and contact an HVAC professional.HVAC Fan Not Working
