It is a freezing winter night. Your basement heating machine turns on. You can hear the gas fire burning. But no warm air comes out of your ceiling vents. The heavy wheel that pushes the air is completely dead. You need to know the furnace blower motor replacement cost to get your house warm again. We will help you understand this expensive repair and how to find the best parts.
What The Motor Does
Pushing The Air
Your basement heater has a giant metal wheel inside. This heavy wheel pushes the warm air into your rooms. It also pushes the cold air during the summer. This heavy wheel needs a very strong electrical motor to spin fast. We call this the main blower motor. If this heavy motor dies, your entire house will stay cold.
Signs Of A Broken Motor
A dying motor makes terrible sounds before it stops completely. You might hear a loud scraping noise like metal rubbing on metal. You might hear a loud electrical humming sound. Sometimes you might even smell hot melting plastic. Read our Furnace Making Buzzing Noise Causes And Easy Fixes guide to learn about these scary sounds.

DIY Maintenance Tip
Save Your New Motor
A dirty paper air filter is the number one reason these heavy motors burn up. A clogged filter blocks the air. The heavy motor has to work twice as hard to pull the air through the thick dirt. It gets dangerously hot and melts the inside wires. You must change your cheap paper filter every single month to protect your expensive new motor. Read our Master Your Furnace Filter Direction Arrow Merv Ratings Guide to do it right. You can also visit the EPA Indoor Air Quality page to learn how clean filters help your lungs.

Why Motors Break Down
Old Age And Rust
These heavy motors spin millions of times every single year. The metal parts inside rub together constantly. They use special oil to stay slippery and quiet. Over ten years, this special oil dries up completely. The metal parts grind together and create a massive amount of heat. The motor locks up and cannot spin anymore.
Water Damage
Sometimes your summer cooling coil drips water onto the heavy motor. The cold water causes terrible orange rust on the shiny metal parts. The rust destroys the smooth spinning action. Check the Energy.gov Home Heating Systems page to see how a clean dry machine lasts much longer.

FAQ
How much does a furnace blower motor replacement cost?
A professional heating worker will usually charge between $350 and $700 total to buy a brand new heavy motor and install it safely in your basement.
Can I just fix the old broken motor?
You cannot fix a burned electric motor because the tiny copper wires inside are completely melted together and ruined forever.
What happens if the motor capacitor goes bad?
If the small starting capacitor breaks, the heavy motor will just hum loudly and get very hot because it does not have the power to start spinning.
Will a completely dirty air filter ruin my new motor?
Yes, a choked paper filter makes the new motor work way too hard which causes it to overheat and melt the internal wires in just a few months.
Should I replace the metal fan wheel too?
You only need to replace the metal wheel if the small blades are bent or covered in thick rust that throws the heavy wheel out of balance.
Conclusion
A dead fan motor makes your house very uncomfortable. You must listen for loud grinding sounds or humming noises from your basement. Check your paper air filter to make sure it is totally clean. Look for dripping water inside the metal box. A professional worker will install a brand new motor safely for about $500. Use our HVAC Services page to schedule a fast repair visit right away.
