About the Blower Motor

Since the furnace's blower motor is the component that circulates the cooled air through the home's venting, a defective blower motor will result in the central air conditioner not blowing enough. You can use a multimeter to test the blower motor for electrical continuity, a continuous electrical path present in the motor, as well as determine if power is reaching the motor. You can also try turning the blower wheel by hand. If the wheel does not turn freely, it's likely the motor bearings have seized and the blower motor will need to be replaced.
