Downstairs lights not working but not tripped

Q: Why do I have power but no lights?

Its a problem if you have a sudden loss of power in the house—such as the lights going out—and the circuit breaker for those appliances and outlets hasnt tripped. The most common solution for losing the lights is a tripped breaker, and in most cases resetting the breaker is all you need to do.

Why is my lighting circuit not working?

Check the connections at the switch and make sure that they are tight. Be sure that the power is off to the circuit that you are working on. With the power shut off, check the wire connections at the light fixture and at the breaker panel to make sure they are all connected tightly.

Why would lights not work in one room?

Tripped breaker: The localized outage could be caused by a tripped circuit breaker. This can happen if a circuit is overloaded or has been spiked by a defective appliance. Unplug all of the appliances in the room, and check your breaker. Most homes or apartments have a breaker box with well-documented breakers.

Why did some of my lights go out?

More often, the issue is a blown fuse or tripped circuit caused by excessive electrical current flowing through the wires. The fuse or breaker will automatically cut off the current to prevent the wires from overheating and causing a fire.

Why do my upstairs lights keep tripping?

Circuit breakers can trip due to any number of problems. That can include water damage, frayed wiring, worn fittings, bad connections, faulty transformers or simply an electrical load that is more than the system can handle. The first step is to turn off all of the lights or appliances that the breaker controls.

How do I know if my light fixture is bad?

Touch the bulb at the bottom of the socket with the other lead. Record the reading. If it’s somewhere close to 120 volts, the fixture is good. If you get a reading of zero or one significantly less than 100 volts, the fixture is bad.

What if a room has no electricity?

Solution: Check the GFCI outlets throughout the house. Press the “Test” button and listen for a click – if it doesn’t happen, the outlet has tripped. Press the “Reset” button, which should restore the power to this outlet, and other areas of the home without power.

Why does only half of my outlet work?

A bad connection, outdated wiring, or a tripped circuit breaker can cause a malfunctioning outlet. But there are instances where only half of an electrical outlet works and the other one doesn’t. It can happen for multiple reasons, and it is wise to call an electrician to look into the issue.

What would cause a circuit breaker not to trip?

A circuit breaker can fail without tripping and is an indication it needs to be replaced. It can also mean there are wiring issues with the circuit itself, such as exposed/loose wiring, overheating, and unregulated voltage.

How do I know if my house circuit breaker is blown?

Circuit Breaker Warning Signs

Burning Smell in the Electrical Panel. One way to tell if you need a circuit breaker replacement is to sniff around and see if you smell a burning odor coming from the panel.
Breaker Will Not Remain Reset.
Physical Damage.
Breakers Tripping Frequently.
Old Age.

Why are the downstairs lights not working when all Upstairs are?

– MyBuilder Why are the downstairs lights not working when all the upstairs ones are??? On a different circuit, check your fuse box… Have you checked your main fuseboard to see if you’ve tripped a switch on the downstairs lights (assuming they are on a seperate circuit)?

Why are my lights not working in my house?

Is anything else not working?. Go to the consumer unit. See which circuit breaker or RCD has tripped. Re set it. If it immediately trips again call an electrician. It maybe that you have a split load board, or you upstairs and downstairs lights are on different circuit breakers.

Why can’t I get power to down stairs?

If you are unsure, it is best to have a qualified electrician check it out, (not a very big job) The house is generally split into different circuits for individual parts of the house.It is probable that the down stairs circuit has blown a fuse or got a fault on while the upstairs circuit is still fine,

Should I split my Fuse board to protect upstairs lights?

Your fuse board should be split and so upstairs lighting and downstairs power will be protected separately to the downstairs lighting and upstairs power. This is so you have either or if a fault does occur on one side of your fuse board causing it to trip.

Hi all,
So the plasterer was in the other day and took down the roses to do a proper job and now ever since then we have no lights upstairs at all. All the ones downstairs work...Not blaming him at all. Just one of those things. It might not even be related.
:
All the lighting is on one breaker and that is on. Have tried resetting it also.
I have checked all the wiring to all the roses that were moved upstairs and down and all seems secure.
If I push in the continuity screwdriver into the live of the landing lights (first one after hall downstairs) it lights up when the switch is turned on but still no actual light comes on.

I have replaced all the bulbs on the off chance they all blew upstairs at once!
Any ideas?
Many thanks as usual!
It is obvious to me that he has disturbed one of the wiring connections on to one of the ceiling roses and disconnected the circuit. It has to be that because there is no other explanation.
Normally the lighting for upstairs and downstairs would each be on their own circuit breakers.
The wiring for the upstairs lighting would take power from its circuit breaker to the first ceiling rose, and then from that first ceiling rose to the second ceiling rose, and then on to the third, etc.
If you have absolutely no lights at all upstairs, then the problem is with the first ceiling rose.
Make sure you have power in that first ceiling rose, i.e. 240V from permanent live to neutral. I'm pretty sure you'll find that it's not there, which is why neither it nor any of the following ceiling roses have power.
Not blaming him at all.
Why not? it's fairly obvious he's broken a connection somewhere!
Thanks very much for your reply.
Just to confirm all. The lights for the whole house are on one breaker.
And when I check the live for the landing light it does appear to have power (light on screw driver illuminates when switched turned on), but the light bulb does not come on. Should the neutral also cause the screwdriver to light up when on?
Cheers
Check to see if you're getting live on all the lights when switched on, if so it's likely to be a neutral that's become disconnected. And no, you shouldn't be seeing voltage on the neutral.

Ha well it had to be done. I guess it would have also happened if I did it
Your downstairs lights are obviously closest to your lighting circuit breaker, and then go on to the upstairs ones and then on to the landing light (or the other way round). Find the last downstairs ceiling rose and the first upstairs ceiling rose, and it'll probably be and open circuit between them - either on the live or the neutral.
You'll need to turn off the lighting at the circuit breaker and a avometer to test continuity, i.e. meter set to ohms.
Thank you
Yes you are right, I am getting live to all the upstairs lights.
What do you recommend I do now? Or is it time to give in and call a sparky?
In that case, your problem is with the neutral.
Test all the neutrals for continuity.
Obviously I know how to do this.... But how would you go about doing it?

Thanks for your help BTW.
Switch off the breaker before doing this. Use simple logic. Only check the wires in the ceiling roses that he took down. Nothing else could have been disturbed. Focus on the black wires next to the blue neutral wire in the rose and the red wires in the central loop terminal. If you tug each wire it should be obvious if it has become disconnected. You will find a disconnected neutral or one of the red lives is disconnected that just happens to be the loop out to all the rest.
You could probably find it with just a visual check without using a meter now we've narrowed it down to a neutral problem.
Cheers guys.
I went round and Actually gave them all a tug earlier and all appeared to be secure. I'll double check again.
The wires might be secure, but one of the screws may be on the insulation, rather than the copper.
The first thing you need to do is to throw that neon screwdriver away. You need a two-probe test device, or a multimeter. It looks like you have proved the appearance of a live supply to the rose(s), but you need to confirm the continuity of the neutral. You cannot do that with a neon screwdriver.

Then you do not know, for certain, that your plasterer has even connected the nine wires in every ceiling rose up correctly.
its easy for a trained electrician to get the wires mixed up, let alone someone who earns a living with just a trowel and a bucket.
So. My advice...buy a proper test meter (and learn how to use it) or get a proper electrician in to sort it out for you.
have you checked in the loft for any junction boxes
Hopefully the plasterer didn't get up there, but you never know.....
Thanks for the reply bazza.
The Plasterer didn't actually remove any wires just let them dangle.
I do have a multimeter. I will read up on how to use it.
No havnt been in the loft. Never have in the 4 years I've lived here. I think it's just full of insulation.
If the neutrals all seem fine in the roses. Do you think it's possible the weight of the light fixing might have tugged on the junction box in the loft? As he left them dangling for a whole that is?
Anything is possible. Unfortunately just a visual isn’t going to hack it. It needs an electrical test to confirm continuity.

Why are my lights out but breaker not tripped?

If one or more lights in your home have gone out and your circuit breaker isn't tripped, what could the issue be? One culprit could be a GFCI (Ground Fault Circuit Interrupter) outlet that has tripped. When experiencing electrical imbalances, GFCI outlets trip much quicker to protect people from electrocution.

Why are my down stairs lights not working?

There could be many reasons why, it could be something simple like your fuse has tripped. It could also be a loose connection in the consumer unit. If you have an old consumer unit with rewireable fuses i would check to make sure it hasnt blown.

Why are only half of my lights working in my house?

A damaged circuit breaker is one of the notorious causes of a partial power outage in many homes. The damage is commonplace during an overloaded electrical circuit or a short-circuiting from a faulty appliance or wiring. Diagnosing the problem isn't difficult since a blown fuse or a discolored switch is enough clue.

Why do I have power but no lights?
