5 Signs of a Bad Furnace Blower Motor in Pittsburg, TX
Your furnace relies on the blower motor to draw in cool air and push out heated air to regulate the climate in your Pittsburg, TX, home. Let’s explore five tell-tale signs that your furnace has a bad blower motor.
Burning Smell
Pay attention to any burning smell that your HVAC system produces when it runs a heating cycle. One possible cause is a blower motor that overheats. Like any other burning issue, this can damage components and even cause a fire in extreme circumstances.
Screeching or Squealing Noise
Seized bearings that allow the fan to rotate may cause a screeching or squealing noise. This may happen when there isn’t sufficient lubrication, so it’s important to schedule routine furnace maintenance.
Insufficient Airflow
When you have a failing furnace blower motor, you may experience two different issues with insufficient airflow. Initially, the motor may not spin as quickly, reducing the airflow through the system. In later stages, it may not spin enough to produce noticeable airflow from your supply vents.
Spiking Energy Bills
Your energy bills tell you a lot about how your HVAC system operates. Watch for any unusual increases from one month to the next. Significant and unexplained changes may indicate a problem with your furnace, including the blower motor.
Additionally, you may notice more subtle changes when comparing year-over-year data. Compare each month to the same month the year before to account for seasonal variation.
Overheating Furnace
If you’re not paying close attention to the supply airflow, a bad furnace blower motor could cause your system to overheat. If the safety mechanisms don’t work properly, the high-limit switch will trip and shut the system down. You can tell if this is the case based on the trouble codes from the blinking light in the furnace control box.
