3 Signs Your Furnace Blower Motor Needs Replacement

In the winter, your furnace keeps your Trussville, AL, house warm. And the last thing you want is for it to break down when you need it the most. Let’s take a look at three telltale indicators of a furnace blower motor malfunction.

1. Weak Airflow

This is the first and most noticeable sign that the blower motor is malfunctioning. It might or might not imply that you require a new motor. If there’s no or very little airflow originating from the vents, the fan may be faulty or blocked.

It’s likely that dust and dirt have blocked your motor, or that it has a defective capacitor or that the air ducts are leaking. If the motor has overheated, become soaked with moisture or has reached the end of its useful life, it may need replacement. If you have poor airflow, an HVAC expert can diagnose the problem.

2. Rising Energy Costs

The blower motor is the most energy-intensive component of a central HVAC unit. If you have an adjustable speed blower in your heating system and it’s not blocked with dirt, the motor may be wearing out and nearing the end of its life.

Dirty blowers work hard to pump conditioned air through the ductwork, but this could also be an indication of a failing blower. It’s also an indication that your ductwork may have a significant leak.

3. Unusual and Loud Noises

Normally, the furnace emits a faint, unnoticeable buzzing sound that does not bother you. If you detect anything besides this echoing from your furnace’s vents, it’s time to turn off the furnace and contact a furnace technician to either fix the fan blades or replace them. Blower motor overheating could induce this issue.
