Replace exhaust fan with fan & light?

I'd like to replace an old bathroom fan with one that has a nightlight in it. But, I'm guessing that the wiring for the fan only will not operate both the fan and a light, unless there is such a thing as a high tech switch that can operate both with basic wiring. Am I right?

wiring troubles 4 wires 2 white 1 blue and 1 black

    If I have a blue and a black with 2 white wires at the fan/light can I assume that the blue and black are hots and the whites are simply the neuterals.

    If the power supply is at the switches supplied by ( 2 wire conductors black, white and copper ground) in order to have seperate control of my fan and light could I not attach the wires in the folowing maner.

    Using 3 wire between the switches and fan/light combo

    Switch one and two connected to the power black pigtailed together. The white neutral from supply to the two whites at the fan /light connected together. From the fan the black wire to switch one and the blue to red to switch two.

Let's say you originally only had one switch (to operate the fan). And at the fan you have only one black, one white, and one ground (bare or green). You can still put in a fan/light combo. but both the light and the fan will always come on together when you flip the switch. To do this you'd connect the black from the switch to the black AND the blue on the fan and connect the white from the switch to both whites on the fan and connect the ground from the switch to either a green or bare wire on the fan or to a green screw on the fan housing somewhere (whatever is available).

I have 2 switches going to my Broan Vent Fan. There is no Red wire from both switches. Fan & lights/nightlight work. How can I get the nightlight just work without turning on the lights?

you will need to have 3 conductor/gnd wire pulled for switch box to fan/light. install a tandem single gang twitch. this will require an electrician.

Replacing double light switch.

The switch you bought may be wired different. You need to identify the incoming power lead this will be connected to a brass screw that should feed both switches, the light will be on one switch and the fan on the other switch. If you have a red/black/white wire going to light/fan the the red will go one switch and the black on the other switch. You have purchased a double switch with no jumper built into switch. You can correct this by placing a jumper wire between the switches, this will be your power feed from home now the 2 switches will work. You may get the fan and light position mixed, but simply reverse the wires on the switches. You are not the first person to buy the wrong switch, they all look the same.

I'm trying to install this Woods 59008 automatic fan timer in the bathroom. My old on/off switch only has three wires....and I that a light switch next to that. The woods 59008 has a red, black, white...

Sure George.

These in-wall timers have extra wire to operate the electronics located inside timer.
You said your old switch has 3 wires.
The new timer can only replace on-off switch that has 2 brass screws and a green screw.
If old switch has 2 brass screws and a dark screw, that is a 3-way switch.
Typically a 3-way switch is found at both ends of hallway.
The Woods 95008 countdown timer is not made to replace 3-way:

Here's what to do:
1) Switch has 2 wires (plus bare ground wire). Take switch wires and connect them to timer-black-wire and timer-red-wire. Choose either one for now.
2) In back of electric box are white wires twisted together and covered with wire nut. Connect timer-white to these wires. This wire will power timer electronics.
3) If electric box does not have white wires described above, then connect timer-white to bare ground, along with timer-green wire.
4) Turn on electricity, and push override button located below the OFF button. If lights come on, timer is wired correctly. If lights do not come on, then reverse timer-red and timer-black wires.

Our switch for the ceiling fan burned out today. Instead of getting the same type of switch (rotary knob with push on/off) I bought a Pass & Seymour combination toggle switch (dual on/off toggle...

The wire to the ceiling fan are meant to send voltage to the fixture only and are not usually wired to control both the light and the fan independently. In order to do that, you may have to pull another set of wires to the switch box and then connect them to the light circuit in the box where the fan is. In regards to the other wiring that you mentioned, it makes no sense that the wires go to the stove fan and the bathroom fan unless those wires are source wires that carry the incoming voltage.

GE on/off timer for a bathroom fan - switch has four wires Green - ground White - neutral Black - power Blue - lead My fan has two - white neutral and black lead I have tried...

I would guess that the black wire on the timer is the power in and blue is the power out to the fan (hook it to the black wire going to the fan) The other colors are right.

How do I install a Pass & Seymour Nightlight/ Outlet? I used to have one regular outlet with 2 receptacles and two sets of hot & neutral wires. When I attempted to install the NIghtlight/ Outlet,...

The wires that you taped up are most likely the wires that feed that outlet and the outlet that isn't working anymore in the bathroom. The proper way to fix your problem would be to do one of the following:
Turn off all electrical power to that circuit. If you are unsure, turn the whole panel off. The inconvenience of resetting your household clocks isn't worth your life.

1) If the screws on your new outlet have spaces for two wires, reattach the disconnected wires under the same screws as the ones feeding the new outlet.
2) Cut yourself a 8" piece of black, white and green or bare copper wire. Disconnect the wires feeding the new outlet. Twist all three wires together, color to color and twist a wirenut on each connection. You should have the three black wires twisted together, the white wires twisted together and the green or bare wires twisted together. Now take the 8" wires and reconnect them to the outlet. Black going to the bronze screw, white going to the silver screw, and green or bare going to the green screw.
