I'm replacing a 30+ year old fan/light in powder room. Old wiring is 4 wires: black, red, white and ground. There are two separate switches, one for fan other for light.
The new fan instructions call for a "dual control" switch with common romex (black,white, and ground) feeding it. This dual control thing then just splits up the hot wire. Any reason I can't wire the whites together, the black to the fan and the red to the light? I'm assuming the black and red are hot.
PS Both fans are NuTone if it matters.
The old wiring most likely was:
White common neutral for fan and light.
red and black switched hots, one from each switch, one for fan and one for light.
I don't know what this "dual control" is and how it would work with only black and white, but I don't see why you couldn't use the existing switches and wiring.
