Rotate the blower sheave by hand, holding the belt in location however keeping your fingers from getting captured in between the belt and the pulley-block. The belt needs to slip right into location.
Fit the brand-new belt onto the motor pulley-block. Then you can re-tighten the tension once the belt is in place. Examine the maker's requirements for proper tensionin most cases, the belt ought to deflect about an inch when you press down on it. Finally, some fan motors and fans require oiling; some have actually sealed bearings.
2 things can cause a blower to run constantly: the space thermostat or the limitation switch located on the furnace just below the plenum (package that disperses heated air to all the ducts). The limit switch turns off the heater if the air in the plenum gets too hot.
