Need help wiring switches to bathroom light and fan

Kid Quick

I'm still having issues getting mine to work. I wired everything like mentioned above but when I turn it on, the light switch works but the fan does not.

I have the one black wire marked (D) above going to the hot input on the switch and one of the black wires (that are split from (B)) going to the to the other input.

The red wire is going to the hot input on the fan switch and the other black (split from (B)) is going to the other input on the fan switch.

Also, I have a GFCI about a foot next to it that's not working anymore either. I rewired it and orignally, the box had four wires coming out of it, two black and two white. I verified that one of the black wires was hot and put that into the Line Hot input and the other black into the Load Hot input. I also put the other white wires into the other two neutrual inputs and finally wired the ground to the GFCI.

The green light comes on when I supply power to the unit but when I try to test the outlet, my tester gives me nothing at all. I'm not sure if these issues are related but I'm totally stumped on this one.

Make sure the neutrals(the 3 white wires under "A") are making good contact. Sometimes with moving the wire bundles around one of the neutrals may have slipped out of contact even though its still under the wire nut.

If you have good neutral contact, then undo all wires under "B", isolate your always hot wire from under "B" and touch this always hot wire to "F" to see if the fan comes on. All this does is bypass the switch. If fan comes on switch is defective. Unlikely but possible.

Post back and let us know...maybe post a picture of the way you have it set up now.

Or easier yet, with light off take the red wire and touch it to the always hot side of the light switch and see if the fan comes on.

Or turn the light on and then you can touch the red wire to either contact of the light switch.

quick question are the light and fan in the same unit.

OP:
2)From (your "B") the feed wire pair which currently has that stripped piece...
attach TWO new (not shown here) BLACK wires under that wirenut; discard the stripped piece.
3)Put one of these BLACK wires onto each of the two switches you want to use.
4)From the 3W (sw leg) D & E ... Put the RED wire onto one switch and the BLACK wire onto the other.
Done.

Tarheel: Thats exactly what was suggested in post #5. The poster said he did this(in post #16) and the light works but the fan doesn't. Sounds like a loose neutral???

TarheelTerp

did it work before?
is it getting power at the fan now?
if so... will that that power go on/off with the switch?
if not... there's a fault to track down.

Did it work before what? Before he decided to remove the timer and install a single pole switch? You would think the fan was operable.

Thats why I suggested he bypass the switch for the fan and also check that all the neutrals under "A" are in contact.

I'm at work right now so I'll work on these when I get home. I will also post pics showing the current setup.

@ hammerlane The light and fan is an all in one unit and all related wires coming into the same gang box.


@ Tarheelterp Yes, the fan did work (via timer dial) before I unplugged everything.

waiting for photos or your response to see if the loose neutral was the problem

Kid Quick

Yeah, I'm Alaska time so it will be a few hours still....

Dont mean to hijack but for TarHeel and Frenchelectician I started a thread on my timer switch situation:

Bath Exhaust Fan Timer Switch--2 Switches in Series

And kidquick...when you get home throw up some photos of your setup when you get a chance. Alaska time that is

Kid Quick

Good news!! I got it to work! I tightned up everything when I got home and turned back on the switch and it worked. Here's the pic of it after wiring it as mentioned above.



So as I mentioned in post my last post yesterday, I have the other problem where my GFCI is not working. I've rewired it and orignally, the box had four wires coming out of it, two black and two white. I verified that one of the black wires was hot and put that into the Line Hot input and the other black into the Load Hot input. I also put the other white wires into the other two neutrual inputs and finally wired the ground to the GFCI.

The green light comes on as seen below when I supply power to the unit but when I try to test the outlet, my tester gives me nothing at all. Any suggestions?

Kid Quick

Scratch that thought on the GFCI. It works. I didnt push the tester in far enough.


I think I'm good! Thanks again to everyone especially Tarheelterp and Hammerlane for all of the input.

hammerlane

The loose neutral strikes again...glad you beat it.

OK, so I've replaced switches in my second bathroom have discovered that when flipping the switch to my fan, the fan itself is very weak. It's almost like not enough power is going to the fan. This is actually the case for both fans now. Before I installed the new fan switches for both bathrooms, I double checked the fans and they both came on full blast.

Does this have something to do with the 15 vs 20 amp switches? (I installed 15 amp switches and I have no idea what was installed before) Or is it something else.

Any advice is appreciated.
