Need home electrical advice.

[wallenba]

Just left my master bedroom. When I switched off the overhead light, it flickered a bit at first. Curious I switched it back on, but now it won't go off. Not making any sparks, smoke or anything else. I opened the breaker and closed it again, same thing.

My back is a mess, and I'm not the best at electrical. What is the more likely source of trouble, the switch or the fixture? Hardware store is closed here now. I did back out the bulbs, but the fixture might still be hot. What's the risk going to bed tonight?

Bad switch. If switch worked power to light would go off.
If older home, does it have aluminum wiring? Don't use back stab, put wiring under screws. Spend more than $2 for your next switch, get quality.

The problem probably lies in your switch.
If you back the lamps out I can't see any danger.

^this. Get a good Leviton switch and avoid the quik stabs in the back

All of the above and MAKE SURE THE BREAKER IS OFF before you attempt to replace the switch.

But that will take all the sport out of it

It's just 110.

[wallenba]

Just about to test that, but don't know if my method will be safe. I plan to screw the bulbs back in till lights come on. Then, open the breaker, disconnect the switch, close the breaker to see if the lights go off.

Yeah, rightttttt.
Ever been bitten real good by 110? I have, it is not fun. Also been bitten by 440, that hurts!

All the time Nolan, working in electrical panels tends to get ya use to it ........ Not a good thing

I agree, its probably the switch. Or the connection at the switch. Removing the load (taking the bulbs out) removes most of the hazard. Changing switches is pretty easy with a few basic tools. I'm old school and do nearly everything hot. Get a flashlight and turn the breaker off, remove the old switch and go buy one like it. Its important to match the switch. Most bedrooms will be a single pole switch (2 screws + the ground), but some larger rooms will have a 3-way (3 screws + a green ground). If its a 3-way switch, take note which wire is on the black or gold screw and the green screw. The other 2 wires can go on either of the remaining screws.

Disconnected the switch with the lights on. Opened the breaker. Lights are out. Logic says switch. Get one tomorrow.

I have a healthy fear of home electrical. When I was seven, my mother found me on the kitchen floor with a butter knife in my hand. Yep... the toast was burning because it got stuck when it tried to pop up. "I'd done that a lot of times I told her, that never happened before". Didn't even blow a fuse. I don't think they had GFI's in 1959.I was banned from the kitchen for many years.

Yes, house was built in 1952, same age as me, 63.

Things don't look right inside that box. Both (only two wires) connected to the switch are black. There is a white wire tucked away in the back. Can't see where that goes. Wires are copper.

Probably wired with 2 conductor wire. Outlets use 2 or 3 prong plugs?
Switch should kill the juice to the fixture if you only have the 2 wires connected to the switch.

[Handloader109]

Do you have two switches that turn on the lights in the bedroom? I expect not, would be common in living room, but not in bedroom. No telling being that old. I'd rewire new switch same as old and be done with it.

[jcren]

Your switch wiring is normal, the black wire is switched and the white wires should be wire-nutted together. Use previously discussed caution and snug wire screws firmly and give her a shot. And yes, 440 3-phase bites much worse than 110!

I was working on a VCR with the power supply exposed on one side. I laid on hand over the fuse, the other over chassis ground and started to flip it over. Got halfway and realized I was across the line... finished flipping it then cussed a bit. Part of working on electronics, getting zapped. 110 doesn't even bother me. Mt dad was an electrician and his fingers were so callused and used to it he would lick his finger tips and brush them across exposed wires to see if the are live.

I agree, bad switch, pretty common failure and very easy to replace. 2 wires, can't put them on backwards(doesn't matter which terminals they go on as long as they are opposite contacts). I would just swap it with power on but getting zapped doesn't bother me.

Yeah, rightttttt.

The outlets all have 3 prong receptacles. That doesn't mean much. The house passed inspection in the bath and kitchen when I bought it. I hired an electrician when we did the kitchen. He showed me that the GFI's were not wired. They redid the bath too.

Handloader109, just the one switch. Going to rewire it as before. Thanks for holding my hand here guys.
