How Do I Know If My Furnace Blower Motor is Bad?

Sep 24

The furnace blower motor is responsible for circulating air throughout your home. If the motor goes bad, it can cause a number of problems.

The truth is, it’s not easy to tell if you have a bad blower motor. Oftentimes, we only realize there’s an issue when our furnace Yukon OK stops working entirely.

To know if your furnace blower is bad and needs repair, you have to look out for these signs:

Strange Noises Coming From the Furnace

If your furnace is making a strange noise, it can be alarming. After all, your furnace Yukon OK is one of the most important appliances in your home, and you rely on it to keep you warm and comfortable during the colder months.

But don't panic just yet! Some of the most common reasons for furnace noises and what you can do to fix them.

  • Loose Parts

Over time, parts inside your furnace especially on the blower can loosen and begin to rattle around, causing all sorts of strange noises.

The good news is that this problem is usually easy to fix. Simply open up your furnace and tighten any loose screws or bolts that you see. If you're not comfortable doing this yourself, you can always call a professional HVAC technician to do it for you.

  • Debris in the Blower

If dirt starts getting stuck on the blades of the blower wheel or inside its motor itself, you’ll notice strange noises from your furnace. As grime interferes with its normal operation, it may lead up to an excessive sound level from your unit

  • Worn-Out Bearings

In some cases, strange furnace noises may be caused by worn-out bearings in either the blower motor or fan belt pulley. When these bearings become worn out, they will start to make squealing or grinding noises as they try to rotate.

If this is the case with your furnace, you'll need to replace either the bearings in your blower motor or your fan belt pulley (or both). This is a repair that's best left to a professional HVAC technician, as it involves working with delicate parts inside your furnace Yukon OK.

Furnace is Running But No Air is Coming Out

The most obvious sign of a bad blower motor is when you can't get enough airflow. This could be due to clogged filters, leaky ducts, or capacitors that are all symptoms but also potential problems with your cooling system if left unaddressed!

To diagnose this issue, you should schedule routine maintenance with an expert who knows what the job entails.

Inconsistent Heating

This can be caused by a number of things, including a blockage in the vents or a problem with the motor itself. If you have an older home, it's also possible that the ductwork is simply worn out and needs to be replaced.

Either way, this is a problem that should be addressed as soon as possible to ensure your comfort and avoid further damage to your home.

High Energy Bills

Your energy bill is like a report card for your home’s energy use. The higher your bills are, the more wasteful your home is likely to be. A sudden increase in your energy bill could be a sign that your furnace blower is bad and needs to be replaced.

The furnace blower is responsible for circulating heat throughout your home. If it isn’t working properly, your furnace will have to work harder to heat your home, which will use more energy and result in higher bills.

Furnace blowers typically last about 10 years, so if yours is nearing the end of its lifespan, it may be time to replace it.

Burning Smell

If you notice a burning smell coming from your furnace, it's important to shut it off immediately and call a professional. This could be a sign of a serious problem with the blower motor.

A few things could cause a burning smell around your furnace, and the blower is one of them. If the blower is going bad, it could be causing the motor to overheat, which would create a burning smell.

Other potential causes of a furnace-related burning smell could include:

  • A clogged air filter

  • Dust or dirt built up in the fan housing or on the blades of the fan

  • A problem with the belt that drives the fan

  • A problem with the motor itself

If you're experiencing a burning smell near your furnace, it's best to call in a professional to diagnose and repair the issue.
