Heater fan and element not working
My heater fan stopped working a few months ago. After checking it out, I also found the heating element was not working. There is voltage at the pin connector for the heater assembly so I bought a replacement heating element and fan motor. I've just installed them, hooked them back up and still nothing.... Any suggestions?
I just replaced the heating element -- took less than 5 minutes. While my heater was out of warranty, Broan promptly sent a replacement unit once I sent them a photo of the registration number and date on the side of the unit.

Should there be continuity between the fan hot lead and the heater hot lead?
Hi Broan rep! Nice product, but I have a question.
I just had my unit mechanically installed, and then I wired it up per the manual. But before hooking up the power, I put a resistance meter across the switches to make sure everything was wired up right. I checked for no connection across each of the three switches with them all off. That was fine. All neutrals and grounds showed continuity.
With the light switch off there was no continuity between power and the light lead until the switch was closed, and then there was zero resistance. Good. Neither the fan nor heater hot leads showed continuity to the light hot lead.
When I put the meter across the fan switch with the fan switch on and the heater switch off, I got continuity to the fan lead. But I also showed continuity to the heater lead!
So I pulled the wires from the switch, and I still have continuity at the switch box between the fan hot lead and the heater hot lead! That can't be right, can it? And they are separate cables, and since one is 2-12 and the other is 3-12 I know I got the right ones. So the only place they could be connected is inside the unit, right? Is it supposed to be like that?
Please let me know if this is correct before I put power on, it just doesn't seem right.
Thanks for the reply, but it's OK, I got it hooked up and working fine. Since the fan and heater/fan both go to a common neutral in the switch box, with the wires lifted there will be a path from the fan switch up to the fan, down through it's neutral; back up through the heater/fan neutral, through that sub-assembly, and then back down through it's power lead. The resistance of the two is in series, but since fan motors and heating elements are basically shorts to the meter's DC, it only looked like there might be a problem. I do appreciate the fast, courteous response, though.
