I installed a Heat Light Vent for a customer and it worked for a while and then quit. He bought a new one and I took the blower and the element out of it and installed it in the old one. What I found is that the element would work but the blower wouldn't and vis-versa. The blower had an electronic board in it which I assume had something to do with why it was acting funny. It is a Harbor Breeze. Has anyone ever had this same issue?
Is it something I am doing?

I never use the cheap fans from Lowes or Home Depot. I also have not wired a fan/light in years but I ud=sed to do them all the time. Nutone- never had much trouble with them. Is the unit vented properly?

Well this is embarassing and probably doesn't apply to your situation, but years ago I would have trouble with fan motors. We tried removing motors on roughin and reinstalling on trimout to protect from dust and paint but didn't seem to help much.
The motors in question were mounted to a bracket, from the bracket a threaded stud was used to attach light reflector with attached socket. We were tightening nut too tight, evidently putting motor in a bind.
Well it was a long time ago, now I make different mistakes.

I long time ago I installed a heat/fan/light in a bath room and pushed the flex duct up into the attic but the HVAC guys never ran it over to the soffit so it never was vented outside, the insulators went right over it and this cause it to over heat in heat mode, it wound up over heating the thermo-fuse in the motor winding and the motor quit so we had to replace the fan and we ran the duct over to the soffit to make sure it got done.
So with that said, is it vented properly? if not it maybe could take out this electronic control board?

If element is on and blower is not it will take out the high limit (usually a one time thermal fuse) and then it will do absolutely nothing. You need to find out why element and blower are not operating together as they should.

Im confused, what does the vent have to do with the heater part of the unit?
