Most furnaces have a direct drive motor that is connected to the squirrel cage fan by a shaft. Others use a belt-driven system, where the motor is attached to a pulley and fan drive belt, which turns the fan. In both cases, the belt can stretch or slip over time, preventing the blower motor from turning the fan at the proper speed. Often, this can be fixed by tightening or replacing the belt.

A squealing blower motor is often caused by dust or dirt in the motor bearings or a lack of lubrication. The motor will work extra hard to function, which can cause it to overheat and create an electrical short or emit an unusual burning smell. Modern blower motors have electronics that prevent them from overheating, and they usually shut down to protect themselves. A professional can clean the motor and lubricate it, which will resolve the squealing and allow it to operate normally.
While there are some DIY kits available, it’s usually best to leave this job to a professional. They will be able to locate the right parts and install them quickly and easily. Most importantly, they will know what is needed to ensure that your new blower motor is compatible with your existing unit.
If you decide to take on this project yourself, be sure to disconnect the power from the blower motor before beginning. You’ll also need a set of standard tools like screwdrivers and socket wrenches, along with hub pullers (optional). Once the panel that conceals the blower assembly is removed, loosen one side of the capacitor bracket screws and remove the capacitor from the bracket. Slide the new capacitor into place and replace the screws.
Once the new blower motor is in place, connect the wires to the control/circuit board. Match the colors of the wires to their color-coded terminals on the new motor, and attach them using wire nuts. Finally, reconnect the grounding wire, which is most often green, to the motor housing.
