Exact fitment
This power unit was an exact fit for an obsolete/discontinued ceiling fan that no longer worked. Rather than replace the entire unit, cut into the plaster, mount onto the rafters, and connect to the old ductwork, I was able to keep my existing fan and save a lot of headache.
If you own the old Broan/NuTone vent fan, then this is a huge timesaver.

Bad part?
It worked only 2 days. Luckily thermal sensor stripped. Opened for inspection and found too much of black burning smoke.
Solution: put back old unit, replaced original defected sensor. It is working nicely with old part unit and new sensor, nice color of flames of blue ish looking.
Got picture, emailed and no responding!

Supply house was as helpful as possible for this old ceiling
I was unable to get exact dimensions of the part I needed I took a chance and with some minor modifications I was able to make the part fit.
