Question: Does this model replace the 763 RL?  Same duct size, etc.?
Document: We recently had to replace our vent fan in the bathroom. I had no idea which one to get. Luckily the additional pictures made this one an easy selection. My husband had no problem installing the fan. It works well and isn't too loud.
I replaced a similar model that had burnt itself out. Once that was removed and I had this one in place, it was a very simple operation to reconnect. The instructions were actually pretty helpful!
Need to replace twenty year old units when house was originally built. Got assistance from OEM and this unit fit perfect, replaced one completely ( housing and fan), just replaced fan and light housing. Amazon delivered another great product on time and as advertised
Mine looks just like the one pictured...square with vents on all 4 sides. While I was talking to the customer service lady, she told me that the unit changed a couple of years ago. I'm guessing when that guy ordered, the amazon pic was the old model and they shipped him the new one.
I had to order replacement exhaust fans for my 2 bathrooms and Amazon was the only place I could find the exact model needed.They are very easy to install and so much quieter than the old ones. I would reccomend this seller to anyone looking for an exaust fan due to their very wide selection.
This was fairly easy to install, however you must have access to the space from an attic to do it easily. Well built and easy to assemble. It is very quiet, and does a good job. The slightly bowed light diffuser allows the light to be spread over the bathroom very well. Subject to the installation issue, I recommend this unit.
This product replaced an existing fan with same CFM specification. The pleasant surprise came when the fan was turned on for the first time. It was barely audible. Great value.
This fan replaced the one I had and fit great. It is better than the old one.Better light. Price was right. Thanks
These were installed in my home when it was built four years ago. Now they're loud and barely move any air at all. Don't waste your time - pay for a more expensive unit like a panasonic whisperlite. The difference is night and day.
There is no real provision for aligning the other 3 sides with the ceiling surface.If there were a competition for how not to design a quiet fan unit, I believe these Broan designs could easily win the grand prize.I have plastered caulk all over mine to secure and dampen the metal joints.
Answer: no
