How to Care for Your HVAC Condensor Motor

Jul 5th 2022

In the outdoor unit of your air conditioner, there are a few crucial components for facilitating the heat transfer that makes AC possible. In distinct, you will find the condenser fan motor. When an AC system is on the fritz, the culprit is an extreme overheating fan motor. Regular care of this part can help diminish potential issues and keep your home's indoor temperature comfortable all year round.

It is important to ensure you perform proper cleaning and maintenance on these pieces and, in particular, look out for any issues with your condenser fan motor.

Extend the life of your HVAC system with a helpful guide to properly caring for your condenser fan motor; read out this helpful contrivance.

HVAC Condenser motor fan: How does it work?

The HVAC system's condenser fan motor, compressor, and condenser coil are all located in the outdoor condensing unit. This unit is responsible for keeping the AC unit cool while running. The condensing unit's motors are vital to the cooling process, as it's what turns the fan that blows the air across the condenser coil, which in turn cools the refrigerant, making it liquid rather than a gas. When the motor overheats, the HVAC will no longer have a way to cool itself and can cause the system to fail.

Common Causes Of An Overheating Condenser Fan Motor:

A few technical issues can cause a condenser fan motor to overheat. The most common issues include:

  • The motor can go bad; if it is incorrectly sized in the unit, it is likely to malfunction.
  • If the fan blades are not installed correctly, airflow may be impeded, and the motor may overheat.
  • An incorrect start run capacitor or incorrect sized fan blades may cause oversampling.
  • Poor airflow can also result from obstructions near the unit, such as weeds, leaves, shrubs, and garden furniture.
  • Dirty oil can prevent the unit from warm air, which will adequately cool the home; the coil should be clean annually.
  • Refrigerant leaks can develop in the condenser and the leading to it. Insufficient refrigerant can result in adequate cooling and stain on the compressor, leading to a breakdown.

Telltale Sign Overheating:

The condenser fan motor overheats when they arrive at roughly 150 degrees. Fahrenheit; upon overheating, the motor will stop running, halting the HVAC system and potentially damaging other crucial components. Following are the few signs that your condenser fan motor was maybe overheating.

  • The top of the outdoor unit is hot to the touch.
  • The alarm sounds can hear like buzzing and humming can be heard from the outdoor unit.
  • A strong odor emanates from the outdoor unit.
  • The AC system suddenly cut out.
  • The AC system runs but is no longer distributing the cold air.

Prevention For Overheating:

The best way to care for your AC condenser fan motor is by having an HVAC technician. The knowledgeable technician prevents issues from arising down the road by clearing the outdoor unit of debris, lubricating the motor to mitigate wear-and-tear caused by friction, and inspecting components that are a sign of damage.

Final Words:

This article will be helpful to you if you are already tired of HVAC problems of AC because we give all the indications and prevention for it.
