Furnace Blower Motor Not Working: Top Causes

Are you having issues with warm air circulation in your home? Call professionals from Green Energy Mechanical Inc. to service your furnace blower motor.  

Your home’s HVAC system produces essential indoor air control that combats seasonal temperature extremes. Various fans and motors in your system distribute this air throughout your property.

If your furnace blower motor is not working, you’ll immediately notice issues with heating your home. When your system malfunctions, call Canton’s furnace repair service to address the issue. Our professionals will restore your blower motor fan and ensure warm air flows throughout your residence.

What Is a Furnace Blower Motor?

The furnace blower motor transports warm air from your furnace to the rest of your home. This blower fan maintains consistent air distribution by expelling warm air from the furnace to your ductwork. A broken furnace blower motor will cause significant temperature drops within your home during winter.  

Top Causes of a Broken Furnace Blower Motor

Knowing the top reasons why your furnace blower motor is not working helps professionals provide appropriate repair services. From electrical problems to mechanical issues, these top causes of furnace blower motor problems cause temperature control issues in your home.


Overheating causes issues with any home comfort system. Furnaces that work at less than optimal levels for too long or struggle with efficiency issues may produce more heat during operation. These systems will likely suffer problems from overheating.

A furnace blower motor that overheats could fail altogether. Thus, it may require more downtime or function ineffectively to compensate for overheating.

Water Damage

Leaks and flooding within your home can cause issues for many systems. Water can threaten your furnace blower motor’s structural integrity and electrical components.

Corrosion and rusting on your blower motor might eventually lead to a complete breakdown. Furthermore, short-circuiting from water damage will inhibit your furnace blower motor.

Blown Fuse or Tripped Breaker

While blown fuses and tripped breakers are usually temporary issues, these occurrences will immediately shut down the functionality of your furnace blower motor. Reset your furnace circuit breaker to try resolving this issue.

Bad Capacitor or Faulty Motor Bearings

The motor bearings and capacitor within your furnace blower motor provide the ignition and maintenance functions for this HVAC component. A bad capacitor won’t allow the furnace blower motor to start. Motor bearings limit friction within your system and ensure that the furnace blower motor functions without issue.

Mechanical Problems

Major mechanical problems within your furnace blower motor’s complex parts can cause inhibited functioning and complete breakdowns. In order to identify the malfunctioning mechanisms, call professionals to inspect your furnace blower motor and system.

Expired Blower Motor Relay

The blower motor relay functions as the on-and-off switch for your system. If this component fails, your furnace blower motor won’t have the appropriate trigger to power on and supply your home with warm air.

Troubleshooting for Furnace Blower Fan

Your furnace blower fan might be suffering a complete breakdown, but it could also be experiencing a brief malfunction. Certain inhibited components could cause a temporary pause in blower motor functioning that limits comfort within your home interiors. These quick troubleshooting steps will help you distinguish between a minor malfunction and a complete breakdown.

Check Wires and Power Supply

Check your furnace blower motor’s wires and power supply immediately when you notice problems. Loose connections, broken wires, short circuits, and tripped breakers will shut down your system but may only require a quick fix.

Inspect Vents and Filters

Your vents and filters can accumulate dust and debris that obstruct air cycling. Ensure your return vent remains unobstructed and provides clean air through the entire cycle of your indoor air. Additionally, replace filters monthly to avoid limited functionality from dust and dirt buildup. 

Check Thermostat Settings

Your thermostat triggers the heat exchanger, enabling indoor heating. Inaccurate thermostat settings will prohibit this trigger and proper functioning.

Turn the System Off and On

Shutting down and repowering your HVAC system might provide the only necessary fix for furnace blower motor issues. Try restarting your system if you notice warm air flow suddenly ceasing within your home.
