Why Is There No Power in One Room? (Gold Coast Guide)
You walk into the bedroom and flick the light switch. Nothing. The lamp is dead too, and so is the phone charger. But the rest of the house is fine: lights on, TV running, kettle boiling.
This is one of the most common calls we get, and it is rarely a sign of anything catastrophic. Rarely is not never, though. Once the easy fixes are ruled out, the causes that remain are the kind that need a licensed electrician, not another video tutorial.
Here is how to work through it: what is going on, what you can safely check yourself, and when it is time to pick up the phone.
Why one room loses power and the rest of the house doesn’t
A home is not wired as one big loop. It is split into separate circuits, each protected at the switchboard by its own circuit breaker. As a rule, lights sit on one set of circuits and power points on another, and each circuit covers a group of rooms. When a circuit detects a fault, its protection trips and only that circuit goes dead. Everything on the other circuits keeps running as if nothing happened.
Most Queensland homes also have safety switches. According to the Electrical Safety Office, they have been compulsory in new Queensland homes since 1992, and on both power point and lighting circuits in homes built since 2000. The two devices do different jobs. The ESO puts it this way: safety switches protect people from electric shock, while circuit breakers and fuses protect the wiring from carrying too much current.
First: is it one room, or one circuit?
This is where most people get stuck. “One room has no power” usually means “everything I have tried in the bedroom is dead”. But the circuit feeding that bedroom might also feed part of the hallway, a power point in the next room, or the outdoor light by the back door. Knowing the real extent of the outage tells you, and us, where to look.
Before doing anything else, walk the house. Try every light switch and power point near the dead room, including the rooms above and below it in a two-storey home. Note what is out and what works. A dead power point in the kitchen as well tells you the circuit covers more than that one room.
Then check the other direction: is it the whole room, or one outlet? If a single power point is dead and the rest of the room works, the fault is most likely at that fitting, and replacing a failed power point is a smaller repair. If every power point is dead but the lights work, that is a slightly different fault. We cover it in power points not working but lights still on.
The five most common causes of no power in one room
These are the causes we check for first, starting with the simplest.
- A tripped circuit breaker or safety switch. Something on the circuit caused an overload or a leakage to earth, and the protection at the switchboard did its job. It can be a one-off, where an appliance briefly drew too much, or it can be persistent, in which case it will trip again. If yours trips repeatedly, safety switch testing finds out whether the device or the circuit is the problem. See also why a safety switch keeps tripping.
- A faulty appliance on the circuit. Heaters, dehumidifiers, hair dryers, irons and older kitchen appliances are common culprits. The appliance develops an internal fault, leaks current to earth, and the safety switch trips. The power stays off until the appliance is unplugged and the switch is reset. If you suspect one, an appliance safety inspection confirms it.
- A damaged or burnt power point or wall switch. A loose terminal runs hot, and a fitting that has been quietly overheating will eventually fail, sometimes taking everything wired after it on the circuit with it. The giveaways are scorch marks, discolouration or a faint burning smell at one outlet.
- Water in an outdoor power point or light. The Bureau of Meteorology puts Australia’s peak severe weather period at October to April. Rain gets into an outdoor power point, a garden light or a poorly sealed switch and creates a path for current to leak. The safety switch trips, and anything indoors on the same circuit goes dead with it. Properly sealed outdoor lighting and fittings stop it recurring.
- A wiring fault inside the wall or roof. Rodent damage, a nail or screw through a cable, heat-perished insulation in the roof space, or a loose connection in a junction box. This is the least obvious cause and the hardest to find without test equipment.
How to safely check a tripped circuit yourself
You can do this without opening anything. You are not removing the switchboard cover, touching any wiring or taking off any faceplates. You are only resetting switches and unplugging appliances.
- Look at the switchboard. Check every circuit breaker and safety switch for one that is flipped to OFF or sitting halfway. Take a photo on your phone. It is useful if you end up calling us.
- Unplug everything on the dead circuit. Lamps, chargers, TVs, appliances, all of it, in the affected room and any other room you found on the same circuit.
- Reset once. Push the tripped switch firmly to OFF, then back up to ON. If it stays on, carry on. If it will not stay on, or trips again straight away, stop there and call an electrician.
- Plug things back in one at a time. If the switch trips when a particular appliance goes back in, you have found the faulty appliance. Leave it unplugged and have it repaired or replaced.
- Nothing tripped and still no power? Then the fault is in the circuit itself, at a power point, a wall switch or in the wiring. That is not a DIY job.
When a single-room outage is dangerous, and when it’s not
Most single-room outages are inconvenient, not dangerous. The protection did its job and the room stays dark until the cause is fixed. The signs below are different. They mean something is actively failing, and they are a reason to call an emergency electrician instead of waiting.
Stop and call an electrician if you notice any of these
- A burning smell near a power point, a wall switch or coming from the wall
- Scorch marks, discolouration or melting on an outlet or switch plate
- Buzzing or crackling from a power point or switch
- Sparks when you plug something in or flick a switch
- A breaker that will not reset even with everything unplugged
- A breaker that resets, then trips again immediately
- Anyone getting a shock or tingle from an appliance or fitting in the affected room
- An outage that followed a storm or water leak on a circuit serving an outdoor area
Any of these is a real fault that needs investigating. Repeated reset attempts do not fix it. They delay finding it. If the sign is a smell, read what a burning smell from a power point means and leave that outlet switched off.
What it means if the breaker won’t reset
If you push the switch up and it snaps straight back down, or it will not latch in the ON position, the fault is still there. The device is detecting a problem the moment power is restored, and it will keep doing so until the fault is found and fixed.
That is the protection working as designed. It is not a faulty breaker. Do not hold it on, tape it up or keep flicking it. At this point, one of three things is usually going on:
- A faulty appliance is still connected somewhere on the circuit. Check for anything plugged in out of sight, such as a dishwasher, rangehood or outdoor lighting
- Water is still sitting in an outdoor fitting and has not dried out
- There is a fault in the wall or roof: a damaged cable, a loose connection at a power point or switch, or a burnt joint
Leave the switch off and get the circuit tested.
Network outage or property fault? How to tell the difference
Worth checking before you call anyone. A fault on the network side is Energex’s to fix, not yours and not ours.
| What’s happening | Network fault (Energex) | Property fault (your wiring) |
|---|---|---|
| How much is out | The whole house, sometimes the whole street | One room, or a few rooms on the same circuit |
| Neighbours’ power | Often out as well | Working normally |
| Switchboard | Nothing tripped, everything looks normal | Usually a tripped breaker or safety switch |
| Who to call | Energex on 13 62 62, or check the outage finder | A licensed electrician |
Energex takes power outage calls on 13 62 62 and publishes live outages on its outage finder. Fallen powerlines are a separate emergency line, 13 19 62. If the whole house is out, start with what to do during a power outage. If one room is dead and the rest of the house has power, the supply is reaching your home and one of its circuits is not passing it on. That is a property fault.
What we find in Gold Coast and SEQ homes
After 20+ years on the tools, the same handful of root causes keep turning up behind single-room outages:
- Burnt connections inside power points. A terminal works loose, runs hot for years, then fails. It shows up most in established suburbs such as Burleigh Heads and Elanora, where the original fittings are carrying far more load than they were installed for
- Water-damaged outdoor power points and garden lights. Coastal homes around Palm Beach, Currumbin and Tugun are hard on outdoor fittings. UV breaks down the gasket, salt air corrodes the terminals, and a heavy storm finishes the job
- Safety switches that have failed. An older device can fail in the off position. The circuit behind it is fine, but the device protecting it needs replacing
- Faulty appliances. Old fridges, electric blankets, cheap chargers and outdoor power tools with damaged cords
- Rodent damage in roof spaces. Rats chew through cable insulation, and the damaged cable eventually shorts the circuit
Finding the fault is not guesswork. We use an insulation resistance tester and a safety switch tester, and where a connection is running hot, a thermal imaging scan shows exactly where. Once it is located, you get a fixed-price quote before any repair starts.
Can I fix this myself?
The checks above are legal and safe: looking at the switchboard, resetting a tripped switch, unplugging appliances. Beyond that, it is electrical work, and in Queensland electrical work must be done by a licensed electrician under the Electrical Safety Act 2002. You can:
- Reset a tripped circuit breaker or safety switch
- Press the test button on your safety switches, which the ESO recommends doing every three months
- Unplug appliances and check their cords for visible damage
- Change a light bulb
You cannot remove a power point or switch faceplate, touch any wiring, replace a power point or switch, or work inside the switchboard. The ESO lists replacing a light switch and installing a power point as unlicensed electrical work, with penalties of up to $40,000 for individuals, and warns that an insurer may refuse a claim for damage caused by it. Our guide to what you can legally do yourself in QLD has the full list.
When the cause is older wiring (and what drives the cost to fix it)
If the same home has had several single-room outages over a year or two, the cause is often the installation itself reaching the end of its life. Burnt connections become more common, safety switches start failing, and the faults come closer together.
At that point another one-off repair is not the fix. The options are a partial or full rewire, often paired with a switchboard upgrade. What it costs depends on how much cable has to be replaced, how accessible the roof space and wall cavities are, and the condition of the switchboard, which is why we quote it on site at a fixed price. We explain the factors in the cost to rewire a Gold Coast home.
Sometimes the answer is a power point swap, sometimes it is a rewire. The testing tells us which, and we will not sell you the bigger job if the smaller one solves it.
Frequently asked questions
Why does just one room lose power and not the whole house?
Because a home is wired as separate circuits, each protected by its own circuit breaker or safety switch at the switchboard. When one circuit faults or trips, only the lights or power points it serves go dead. Everything on the other circuits keeps running, which is why the rest of the house looks normal.
What if the breaker resets but the power doesn’t come back?
Then the fault is likely downstream of the breaker, at a power point, a wall switch or in the wiring itself. The circuit is live at the switchboard, but a connection somewhere along it has failed. That is not something to open up yourself. It needs a licensed electrician to locate and repair.
Can a single appliance really take out a whole room?
Yes. A faulty appliance leaking current to earth will trip the safety switch on its circuit, and every power point on that circuit loses power until the appliance is unplugged and the switch is reset. Heaters, dehumidifiers, older kitchen appliances and outdoor power tools with damaged cords are common culprits.
Why does only half a power point work?
A double power point has two outlets, and one can fail without the other. Usually the contact or internal connection behind the dead outlet has worn or burnt out. The fault is at that one fitting, not the wider circuit, so it is normally a smaller repair. Stop using it until it is replaced.
Should I call Energex or an electrician if one room has no power?
Call an electrician. Energex looks after the network up to your property, so it is the right call when the whole house or street is out, on 13 62 62. When one room is dead and the rest of the house has power, the fault is inside your own wiring or switchboard, which is a licensed electrician’s job.
Is it safe to keep resetting a breaker that keeps tripping?
No. Reset it once, with everything on that circuit unplugged. If it trips again or will not stay on, the breaker or safety switch is detecting a live fault, and repeated resets only delay finding it. Leave it off and have the circuit tested by a licensed electrician.
How much does it cost to fix no power in one room?
It depends on the cause, which is why we do not quote a figure before seeing it. A faulty appliance costs nothing to fix beyond unplugging or replacing it. A failed power point is a quick swap. A wiring fault inside the wall takes longer to locate and repair. Every job is quoted at a fixed price on site before any work starts.
Still no power after a reset? Call us. We find the fault on site and quote a fixed price before any repair begins.
