The motor works fine and replacement of the new motor into the existing mounting brackets worked nicely. The hardest part of the whole replacement is getting access to the old motor in the attic and removing the fan blades from the old motor. Once the old unit is removed the rest of the replacement is rather simple. Once the wiring had been connected and electrical current restored it ran just as had been hoped. The hot weather has not arrived quite yet, but I feel confident the motor will work well. This appeared to be the exact replacement of the motor than had frozen. This should work nicely for anyone needing to replace a frozen attic fan motor.
