Broan bath fan light

Hi,
I have just installed a Broan model 744 bath fan/light. It is a combination recessed style. It worked fine for about 5 minutes, then the light went out.
When the unit cooled down after about 5 minutes after turning it off I turned it back on and the light worked. but it went off again after about 5 minutes. The fan works fine. I am not sure what is happening, but I really do not want to tear our the drywall and paint job in the ceiling that I have just installed. Maybe I should check these units before I install them, but it does work fine for about 5 minutes. Maybe the light is getting to hot. I tried several different bulb and it is the same for all of them.

Probably you cross the wire, read the manual, check the wire first.

connect all the white wires together, connect the black wire from the hot source to the one side of the switch and connect another side to the light, this is for the light. and do the same for the fan.

the factory use either red or the black for hot,white for the neutral and green for the ground.

I hope this can help you.

It sounds like the fan blade may be loose on the motor shaft. You can purchase a new motor for this fan online.

I purchased a Broan 744 light/fan combo. I want to wire the light and fan to separate switches. Do I use single pole switches and how do I wire up the switches?


Here is a link to the instruction manual. Page three shows a wiring diagram for separate switches.

This is the Switch NuTone Broan recommends for that fan.

Looking for repacement globe for bath room exaust fan


Hi there, What I would do without knowing what kind of exhaust fan you have is Google it online. Or, if you have the make, model number, etc., and take it down to your nearest home depot, lowe's, etc., or heating and supply company close to you. These are pretty common exhaust fans, so you should have no problem finding a replacement. Good Luck with this, and if you have an other problem regarding your fan, feel free to contact me and I'd be willing to help you out.  - Jim
