Power Points Not Working But Lights Still On? Here’s What That Means
It feels like a contradiction — the room is lit, everything looks normal, but nothing you plug in works. It isn’t a contradiction, and it isn’t random. It’s your wiring doing exactly what it was designed to do.
Why lights stay on when power points die
Australian homes are wired with lighting and power outlets on separate circuits, each with its own protection at the switchboard. That’s deliberate. If a fault on the power circuit also killed your lights, you’d be diagnosing a problem in the dark — so the two are kept independent.
The practical result: a tripped breaker, tripped safety switch, or fault on the power circuit takes out your outlets while the lighting circuit carries on untouched.
Start here: how much is actually dead?
Before touching the switchboard, walk the house and test a few outlets. The scope of the outage narrows the diagnosis more than anything else you can do:
| What’s dead | Likely cause | Urgency |
|---|---|---|
| One outlet only | That outlet itself — worn contacts, loose or burnt terminal | Book a service |
| Several outlets, one area | That circuit — tripped breaker, or a fault at one point affecting others downstream | Book a service |
| Every outlet, lights fine | Tripped safety switch or breaker covering the power circuits | Try a reset first |
| Started after rain, outdoor outlet involved | Water ingress tripping the safety switch | Needs investigation |
| Any dead outlets plus burning smell, heat, or scorching | Active fault | Call now |
Knowing which row you’re in before you call saves diagnostic time and, on a call-out, money.
What’s safe to check yourself
- Rule out the appliance. Try it in an outlet you know works. If it fails there too, the appliance is the problem, not your wiring.
- Map the dead zone. Test outlets through the house and note which work. This is the single most useful thing you can tell an electrician.
- Check the switchboard. Look for any switch sitting off or halfway. Power circuits are usually labelled separately from lighting.
- Unplug everything on the affected circuit before resetting — if a faulty appliance caused the trip, resetting with it still plugged in just trips it again.
- Reset once. Push the switch firmly to off, then back on. If it holds, plug appliances back one at a time with a few minutes between each. Whichever one trips it is your culprit.
- If it won’t hold, stop. Repeated resetting against a live fault is how a manageable problem becomes a dangerous one.
That’s the limit of what’s legal and safe. Removing an outlet faceplate or touching wiring is licensed electrical work in Queensland regardless of how simple it looks — covered in our guide on what you can legally do yourself.
The five causes we actually find
- A tripped breaker or safety switch. The most common by a wide margin, and often triggered by a specific appliance — a heater, kettle, or something with a developing internal fault. If it resets and holds, that was it.
- A faulty appliance leaking to earth. The safety switch is doing its job. The unplug-and-reintroduce sequence above finds it.
- A failed or burnt-out outlet. Outlets have a service life. Internal contacts wear, terminals loosen, and connections degrade — particularly on outlets that get heavy plug-in traffic. This is the usual answer when exactly one outlet is dead, and replacing the outlet is usually a same-visit fix.
- Water in an outdoor outlet. Very common on the Gold Coast, especially through storm season. Rain gets into an outdoor GPO, current leaks to earth, and the safety switch isolates the entire circuit — including indoor outlets sharing it. The tell is timing: it started during or after wet weather.
- A loose or degraded connection in the wiring. Least common, most serious. A loose terminal at an outlet or in the switchboard can isolate everything downstream of it — and the loose joint generates heat. This is the one that turns into a fire risk if left, and it’s why a dead circuit with no obvious cause shouldn’t just be left alone.
When it’s urgent rather than annoying
Turn the circuit off and call — don’t keep resetting
- Any burning smell near an outlet or the switchboard
- An outlet that’s warm to touch, discoloured, or showing scorch marks
- Buzzing or crackling from an outlet or the board
- Sparking when you plug something in
- A breaker that trips again immediately with everything unplugged
- Anyone receiving a shock, however minor, from an appliance or outlet
If there’s a burning smell involved, our guide on what to do about a burning smell from a power point covers the immediate steps. For the wider picture on what counts as urgent, see what’s considered an electrical emergency.
Why it keeps happening
If this is a recurring problem rather than a one-off, the cause usually sits upstream of the outlets themselves:
- An overloaded circuit. Modern households run far more on power circuits than the boards of twenty or thirty years ago anticipated. A circuit close to its limit trips whenever demand peaks.
- An aged safety switch. RCDs drift out of calibration over time and start tripping on leakage well below the threshold. Covered in our guide on why safety switches keep tripping.
- Too many circuits behind one safety switch. Small background leakage from many devices pools and creeps toward the trip point. Our guide on RCDs versus RCBOs explains why per-circuit protection avoids this.
- Deteriorating wiring. In older homes, insulation degradation produces intermittent faults that come and go with heat and humidity.
Repeated trips on the same circuit are worth diagnosing properly rather than resetting indefinitely. The reset is treating the symptom.
Frequently asked questions
Why do my lights work but power points don’t?
Australian homes are wired with lighting and power outlets on separate circuits, each with its own protection at the switchboard. It’s deliberate — so a fault on one doesn’t leave you diagnosing the problem in the dark. A tripped breaker or safety switch on the power circuit takes out your outlets while lighting continues normally.
Can I fix a dead power point myself?
You can safely check the switchboard, unplug appliances, and reset a tripped switch once. Removing the outlet faceplate, testing terminals, or touching any wiring is licensed electrical work in Queensland with no DIY exemption, regardless of how straightforward it looks.
Why did several power points stop working at the same time?
Usually one fault, not several. Outlets on a circuit are often wired in sequence, so a failed connection at one point cuts supply to everything downstream of it. It can also mean the breaker or safety switch protecting that circuit has tripped.
My power points stopped working after rain — why?
Water has almost certainly got into an outdoor outlet or fitting on that circuit. The moisture creates a path for current to leak to earth and the safety switch isolates the whole circuit, including indoor outlets sharing it. It’ll often work again once things dry out, but the underlying seal failure is still there and will recur next storm.
The breaker resets but trips again straight away — what does that mean?
The fault is still live. The breaker is detecting it the moment power is restored, which is exactly what it’s designed to do. Stop resetting — repeatedly forcing power back into a faulty circuit is how a manageable problem becomes a dangerous one. Leave it off and call an electrician.
How much does it cost to fix a dead power point?
Depends entirely on the cause. A faulty appliance costs nothing to resolve — you unplug it. A failed outlet is a straightforward replacement. A wiring fault takes longer to locate and repair. Every job is fixed-price quoted on site before work starts, so you know the number before committing.
