The blower on a furnace can quit working for several reasons, such as electrical issues, an overheated motor, mechanical failure and control board problems. Have a professional inspect your system before the heating season comes so you don’t run into issues when you need your furnace most. At the same time, staying aware of the issues your furnace blower can face can help you know when exactly it’s time to call for repairs.
Electrical Issues
Electrical issues with a blower motor can occur in several ways. One way involves a failed capacitor, which can result in the blower motor operating at a lower RPM range, becoming too hot or short cycling.
Control Board Problems
The control board toggles the blower motor on your furnace on and off, among other operations. If it breaks down, the blower won’t operate like it should.
Mechanical Failure
Worn bearings and belt issues are two very common mechanical issues that can cause a blower motor to quit working. A loud blower is often the result of worn bearings, which may occur as the motor ages. Problems with the belt might cause your furnace’s blower to stop working if the belt becomes loose, damaged or broken.
Overheated Motor
A blocked air filter can lead to an overheated blower motor. Fortunately, most blowers come equipped with safety features that automatically turn them off when they overheat. A lack of lubrication may also contribute to motor failure in a blower since it increases friction, which generates heat.
