Why Is There No Power in One Room? (Gold Coast Guide)

You walk into the bedroom, flick the light switch — nothing. The lamp’s dead too. So is the bedside clock, and the phone charger. But the rest of the house? Fine. Lights on, TV running, kettle boiling.

This is one of the most common calls we get, and the good news is it’s almost never a sign that something catastrophic is going on. The bad news is that “almost never” is not the same as “never” — and once you’ve ruled out the easy fixes, the remaining causes are exactly the kind of thing that needs a licensed sparky to look at, not another YouTube tutorial.

Here’s how to work through it, what to check yourself, and how to know when it’s time to pick up the phone.

The direct answer, expanded

Australian homes are wired with separate circuits for different parts of the house. Your kitchen, your bedrooms, your living areas, your bathroom, your outdoor power points — most are on their own circuit, or share a circuit with one or two other rooms. Each circuit has a circuit breaker (and, in any home wired after 2000 or upgraded since, a safety switch) at the switchboard. When the circuit detects a fault, the breaker or safety switch trips and that circuit’s power gets cut. The rest of the house — on different circuits — keeps running like nothing happened.

So when one room goes dark, you’re not dealing with a whole-house power failure. You’re dealing with a single-circuit fault. And single-circuit faults have a fairly predictable set of causes.

First — is it actually one room, or one circuit?

This is where most homeowners get stuck. You say “one room has no power” and you mean “everything in the bedroom is dead.” But the circuit serving that bedroom might also serve part of the hallway, a power point in the next room, or the outdoor light by the back door. Knowing the actual extent of the outage tells you (and us) a lot about where to look.

Before you do anything else, walk the house. Check every light switch and every power point that’s near the dead room — including the room above it and the room below it if you’re in a two-storey. Make a mental list of what’s out and what’s working. If you find that a power point in the kitchen is also dead, you’ve got useful information: the circuit covers more than just that one room.

The other thing worth checking: is it the whole room, or just one outlet? If only one power point is dead and the rest of the room works, the fault is likely at that specific outlet, not the circuit. That’s a smaller (and often cheaper) repair.

The five most common causes of power loss to one room

In order of frequency for a typical southern Gold Coast home:

1. A tripped circuit breaker or safety switch. The most common cause by a wide margin. Something on that circuit caused enough leakage or overload to trip the protection at the switchboard. The fault could be temporary (an appliance briefly drew too much, the breaker tripped, you reset, you’re fine) or persistent (the appliance is still faulty, or there’s a wiring issue, and it’ll trip again).
2. A faulty appliance dragging the circuit down. Heaters, dehumidifiers, old TVs, gaming consoles, hair dryers, and clothes irons are common culprits — anything that draws hard current. The appliance develops an internal fault, leaks current to earth, and the safety switch does its job. The room loses power and stays out until the appliance is unplugged and the breaker is reset.
3. A damaged or burnt power point or wall switch. Older fittings, fittings damaged by a knock, or fittings that have been quietly overheating for years can fail. The whole circuit downstream of the failed fitting loses power. Common giveaway: scorch marks, discolouration, or a faint burning smell near a specific outlet.
4. Water ingress into an outdoor power point or fitting. Storm season on the Gold Coast (November to April) does this all the time. Rain finds its way 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. The rooms served by that circuit lose power until it’s dried out and the underlying seal failure is fixed.
5. A wiring fault inside the wall cavity. Rodent damage, a nail through a wall cavity from a hung picture, sun-perished cable in the roof space, or a loose connection inside a junction box. Less common than the other four, but the hardest to find — these faults need proper diagnostic equipment to locate.

How to safely check if it’s a tripped circuit yourself

You can do this part without opening anything dangerous. You are not opening the switchboard cover, touching any wiring, or removing any power points — just resetting switches and unplugging appliances.

1. Walk to your switchboard. Look at every circuit breaker and safety switch. You’re looking for any switch that’s flipped to OFF, or sitting halfway between ON and OFF. Take a phone photo — useful if you end up calling us.
2. Unplug every appliance in the affected room (and any other room on the same circuit, if you’ve worked out the extent). Lamps, chargers, TVs, kitchen appliances — all of it. Leave the wall switches in the ON position.
3. If you found a tripped breaker or safety switch, push it firmly to the OFF position first, then back up to ON. If it stays up, continue. If it won’t stay up, or trips again immediately — stop. Don’t keep trying. Call an electrician.
4. If the circuit reset successfully and the room has power again, plug appliances back in one at a time, leaving 5–10 minutes between each. If the breaker trips again when you plug something in, that’s your faulty appliance. Unplug it. Have it repaired or replaced.
5. If nothing was tripped at the switchboard, and the room still has no power, the fault is in the circuit itself — at a power point, a wall switch, or in the wiring. That’s not a DIY job.

If you’ve worked through these steps and the room still has no power, you’ve ruled out the easy causes. What’s left needs a licensed electrician.

When a single-room outage is dangerous (and when it’s not)

Most single-room outages are inconvenient but not dangerous — the circuit did its job, you reset it (or you didn’t), the room sits dark until it’s fixed. The system worked.

Any of these is a real fault that needs investigation. Repeated reset attempts in this situation aren’t fixing the problem — they’re delaying finding it, and in some cases making it worse.

What it means if the breaker won’t reset

If you flip the tripped switch up and it immediately snaps back down, or simply won’t stay in the ON position, the fault is still active. The breaker is detecting a problem the moment you try to restore power. It will keep doing this until the underlying fault is found and fixed.

This is the breaker doing exactly what it’s designed to do. It’s not faulty — it’s correctly refusing to put power back into a circuit that has a problem. Forcing it (some people try to hold it up) bypasses the protection and is how electrical fires start.

At this point, three things are most likely happening:

• A faulty appliance is still connected somewhere on the circuit (check you’ve unplugged everything, including hard-wired items like dishwashers, hot water elements, and outdoor lighting)
• Water is still present in an outdoor fitting and hasn’t dried out
• There’s a fault inside the wall — a damaged cable, a loose connection at a power point or switch, or a burnt junction

The last one is the most common cause we’re called out for when the breaker refuses to reset.

Is it a network outage or a property fault? How to tell the difference

This is worth checking before you call us — a network-side fault is Energex’s responsibility, not yours, and we can’t fix it. Here’s how to tell:

If the outage is just one room and the switchboard shows a tripped breaker — that’s a property fault, every time. Your home has power; one of its circuits doesn’t. That’s our territory.

What we typically find when called out on the southern Gold Coast

In 20+ years on the tools, the same handful of root causes come up over and over for single-room outages in southern Gold Coast homes:

• Burnt connections inside power points — especially in homes built between the 1980s and early 2000s, where the terminals on older outlets weren’t designed for the loads modern households put through them. A long-running hot connection eventually fails.
• Water-damaged outdoor power points and garden lighting — coastal homes near Palm Beach, Currumbin, and Tugun see this constantly. UV breaks down the gasket, salt air corrodes the terminals, the first big storm finishes the job.
• Failed RCDs that won’t reset — older safety switches can fail in the “off” position after years of duty. The circuit they protect is fine, but the device protecting it has died and needs replacement.
• Faulty appliances — usually old fridges, electric blankets that have been folded incorrectly, cheap chargers, and outdoor power tools with damaged cords.
• Rodent damage in roof spaces — rats and possums chew through cable insulation, eventually shorting a circuit. We see this most in older Burleigh Heads and Elanora homes with timber roof spaces.

Diagnosis isn’t guesswork — a licensed electrician uses an insulation resistance tester, an RCD tester, and sometimes a thermal imaging camera to locate exactly where the fault sits. Once found, you get a written quote with a fixed price before any repair work starts.

Can I fix this myself?

The diagnostic steps above — checking the switchboard, resetting a tripped breaker, unplugging appliances — are all legal and safe. Anything beyond that isn’t.

In Queensland, all fixed electrical work must be carried out by a licensed electrical contractor under the Electrical Safety Act 2002. You’re legally allowed to:

• Reset a tripped breaker or safety switch
• Press the quarterly test button on your safety switches
• Unplug appliances and check their cords for visible damage
• Replace a plug-in light bulb

You are not allowed to remove a power point or wall switch faceplate, touch any wiring, replace a power point or switch, or open the inside of the switchboard. Doing so voids your home insurance and creates a real safety risk to you and anyone in the property.

When the cause is older wiring (and what it usually costs to fix)

If your home is a 1980s or 1990s build and you’ve had multiple single-room outages over the past year or two, the cause is often the wiring system itself reaching end-of-life. Burnt connections become more common, RCDs start failing, breakers age out of tolerance, and the fault frequency creeps up.

The fix at that point isn’t another individual repair — it’s a partial or full rewire, often paired with a switchboard upgrade that brings the home up to the current Wiring Rules. We quote both options on site, fixed price, and explain honestly which one your home actually needs. Sometimes it’s a $200 power point swap. Sometimes it’s a $3,000+ rewire. The diagnosis tells us which, and we won’t sell you the bigger job if the smaller one will solve it.
