In this video I show you how to diagnose and repair a light switch that is no longer working. These methods will help you differentiate between whether there is an issue with the switch itself or the wiring.

Have you ever had this issue come up? What did you do?

@yvonnejackson1696 4 месяца назад

I just mindlessly replaced the switch. That worked fine but I never thought about maybe saving myself a trip to the hardware store by checking the wiring.😖

@bobhall5893 4 месяца назад

Not a switch, but I did have a GFCI outlet go bad after only about a year. It would not reset, and all wiring checked out fine. Stuff happens!

@Bonkrr 4 месяца назад

I replaced over a dozen switches for a client a few months ago. They wanted to go to the newer style flat switches. Ended up having to swap out 5 of them a second time, Must have been a bad day at the factory.

1990's Maintenance manager for a set of buildings in Glendale, CA...Electrician went to work on a wall outlet. Cut the power...was surprised when second set of plugs "sparked" on him... Turns out the wall plug had TWO circuits wired to it! Was pleased to see you checked both sets of plugs!

@JustinSpakable Месяц назад

What an idiot. If an electrician sees two different wires into a Recep, you're gonna check both wires and the Recep for a broken tab. He got what he deserved

Actually as an electrician we change bad switches almost everyday. They don't make them like they used to.

I've had to replace several in my house that's only 10 years old.

@denattheoakleyoutpost6740 4 месяца назад

Actually, I have had single pole switches go bad over the years in many different houses. Usually, they would get soft or intermittent. I keep a few around. It’s a 5 minute swap out so I just replace it and move on.

@retirementpirate3665 4 месяца назад

I just replace the switch first and then troubleshoot second if I have a similar problem. However, this would not be practical for a RU-vid channel.

@gnic76 4 месяца назад

Hi, thank you for this video! This will help with a diagnosis on a bathroom fan. I'm a homeowner of a 100 year old house trying to navigate fixes. I have some knob and tube wires on another line. The line is really old and I'm wondering how to work with it to rewire an old receptacle. I'd rip it out the wiring and have it replaced, but as a single mom it's beyond my budget. Could you make a video on older wiring? 😬🙏 What's a safe load?

@gnic76 4 месяца назад

Just an observation.. Being 120v light switches are a wiper type contact, I would expect more to fail over time as a LED current load is less. The older resistive bulbs would put a heavier load on switch which helped keep the internals clean.

@frannova 4 месяца назад

Exactly. I have replaced three switches, all on circuits with one led bulb.

@sziltner 4 месяца назад

I installed 2 new LED light panels in my kitchen replacing the old fluorescent light fixtures. Later I noticed the panels would flicker. I replaced both the cheap 3 way light switches with commercial duty switches. NO MORE FLICKERING!

@HowToHomeDIY 4 месяца назад

Yup. These things are getting cheaper and cheaper in quality. Thanks for the feedback!

The risk is likely to be minimal in this example, does anyone retail a breaker lockout for residential distribution panels?

@JCWren 4 месяца назад

It might have been interesting to do a tear down on the switch to see exactly why it failed.

@johnsee7269 4 месяца назад

Wow! The Fluke equivalent was about $290 or over thrice the price of the Klein. Snap-on was about $225...

@LuisHernandez-zi3nt 4 месяца назад

Hello, I have a three way switch that powers my ceiling fan but isn’t receiving enough power. The voltage reading is very low close to 1. I checked all the cables look fine and the switches are fine as well. What other trouble shooting could I do?

@JustinSpakable Месяц назад

Make sure the neutrals are tied together and making a good connection. And check the connections to the fan, as well. Might have to take the fan down and make sure you didn't lose the neutral or the hot up there. Good luck

@johnalderson1370 3 месяца назад

I have a switch that won't turn the light off. Any idea what the problem would be there? I just put in a new light fixture. And now the lights won't turn off from the sweat

@JustinSpakable Месяц назад

Sounds like a bad switch or the switch leg is tied into the hot bundle.

@kevinland534 4 месяца назад

Is there an easy way to trace a wire back to it's source? I have a switch in my house that when I throw the switch, nothing happens. It's not connected to any outlets either. I opened up the cover and see that there are wires connected but I'm not sure to what exactly. Another issue is that I have an outlet that is high up in my closet that has a large plug connected to it. My guess is that it's for the house alarm or maybe the fire alarm? How can I tell what that may be?

@HowToHomeDIY 4 месяца назад

You could use a toner like this one that I use amzn.to/3wQHeUO. It puts a signal through the line once attached and the probe can detect it through the drywall to the source. If you get one just make sure to follow the directions. It is pretty easy to use.

@TacoDaddy-mr8ig Месяц назад

How can I find what breaker controls the switch without turning off random breakers?

@JustinSpakable Месяц назад

You'd need a circuit tracer. Which isn't cheap. It's probably best to just start flipping breakers

@richg3411 4 месяца назад

A great lesson on a bad switch. Why would I have a switch when turned on energizes a device, but when that same switch is turned off, the device will not de-energize?

@HowToHomeDIY 4 месяца назад

@daveray44 4 месяца назад

For showing the continuity, could have tested the new switch before wiring it in place

@HowToHomeDIY 4 месяца назад

Could have, but it’s a new switch and I’ve never had an issue with a new one. But might have been a nice addition to the video to show what it would look and sound like. Appreciate the feedback!

@daveray44 4 месяца назад

@HowToHomeDIY That was my intent of my comment. I, as well, wouldn't feel the need to test a new switch, but showing this applied in a video could be of a benefit. BTW, I really do enjoy your videos!

@JCWren 4 месяца назад

@@HowToHomeDIYThat was a new switch? The area around the lower hot screw looked like it was beat to hell. I was wondering why you were installing what appeared to be a used switch.

@jeffwilder7117 4 месяца назад

As a retired electrician I have seen those ‘skinny’ single pole switches go bad. They are junk. Made to fail IMO. I always buy the upgrade, fat switch. It’s more of a commercial grade. A little more expensive but do it once and done.

@HowToHomeDIY 4 месяца назад
