Product review (4 stars): Very good but not exact replacement
The motor works and is almost identical to the one installed on my Sub-Zero 690/s but it is noisier since it spins at 1500 RPM while the original was 1300 RPM.  Also the fan blade that shipped with it was larger than the original and bent so I had to reuse the original blade.  The good news is that the original blade fit perfectly on the new motor.
