Furnace Blower Motor Replacement
I would replace the motor with a 4 speed PSC motor. Psc motors have more starting torque than non PSC motors and use less electricity to run and start, because they are more efficient. These motors are usually 4 speed however a few are 3 speed. you may want to check the capacitor since the motor will not run if the capacitor is bad and capacitors cost a lot less than a motor.
