750 Broan® Ventilation Fan w/ Light and Night Light
The 750 is the suggested replacement but not an exact replacement for the 8662. The 750 has a housing size of 9" x 9" with a 4" round duct. The ceiling cutout is much larger to accommodate the installation of the grille assembly. The 8662 used a housing size of 10-3/8" diameter with a 4" duct size.
