No Power in One Room: How to Diagnose It

The whole house has power, but one room is dead — no lights, no sockets, or sometimes the lights work and only the sockets are out. It is one of the most common calls we get in Accra, and the good news is that it is almost never a whole-house problem. It is a single circuit. Here is how to think about it, what you can safely check yourself, and when to stop and call a licensed electrician.

First: Make It Safe Before You Investigate

If at any point you smell burning, see scorch marks on a socket, or feel heat from a switch or outlet, stop. Switch off at the main breaker, do not use that room, and call us the same day on +233 23 063 0022. A dead room is usually harmless; a dead room with a burning smell is not. Everything below assumes there is no heat, no smell, and no visible damage.

Why One Room Goes Dead

A house is wired in separate circuits, each protected by its own breaker in the consumer unit (the board). When one circuit fails or trips, only the rooms and sockets on that circuit lose power — the rest of the house carries on. So a single dead room nearly always points to one of these:

A Tripped Circuit Breaker

The most common cause. A breaker has switched itself off to protect the circuit — because of an overload, a faulty appliance, moisture, or a short.

A Failed Socket or Connection

A burnt-out socket, a loose terminal, or a connection that has worked itself loose over years of heat and vibration. Common in older Accra homes and anywhere rainwater has reached an outdoor or wall socket.

A Faulty Appliance Pulling the Circuit Down

A single failed appliance — a fridge, a water heater, an AC unit — can trip the circuit it sits on every time it is plugged in.

What You Can Safely Check Yourself

You do not need tools for the first steps, only your eyes and the board.

  1. Go to the consumer unit. Look for a breaker that has flipped to the “off” or middle position while the others are “on”. That is your dead circuit.
  2. Switch off everything in the dead room — unplug appliances, turn off the lights at the wall.
  3. Reset the breaker once. Firmly off, then on. If it holds and power returns, plug appliances back in one at a time. If the breaker trips again when you plug in a particular appliance, that appliance is the fault — leave it unplugged and have it checked.
  4. If the breaker trips again immediately with nothing plugged in, stop. That is a fault in the circuit wiring or a socket, not an appliance. Do not keep resetting it.

That last point matters. A breaker trips to protect you. Resetting it over and over without finding the cause is the dangerous option — that is exactly the situation it exists to prevent.

When to Stop and Call

Call a licensed electrician if:

These need electrical fault finding — tracing the actual fault with test instruments rather than guessing. We find which socket, junction, or length of cable has failed, and fix the cause so it does not come back.

What It Costs — Honestly

A call-out starts indicatively from around GH₵200. The repair itself depends entirely on what the fault turns out to be — a single socket is quick; a loose connection buried in a wall, or wiring that has degraded, takes longer. No honest electrician in Ghana can quote the repair before seeing it, so we diagnose on site and give you the price before we start the repair, never a surprise after.

A Note on Older Homes

If your house was wired more than twenty years ago and you are getting repeated dead-circuit faults across different rooms, the issue may not be one socket — it may be ageing wiring reaching the end of its life. In that case a one-off repair is a patch, not a fix. We will tell you honestly if that is what we find, and what a house rewire would involve, so you can decide rather than keep paying for the same fault.

The Bottom Line

A single dead room is almost always one tripped circuit, one failed socket, or one bad appliance — rarely a crisis. Check the board, reset once, isolate the appliance. But the moment a breaker refuses to hold, or you smell or feel heat, stop investigating and call.

Electricals Ghana has found and fixed these faults across Greater Accra since 1987 — Energy-Commission-licensed electricians who test rather than guess. Call +233 23 063 0022 and describe what is dead; we will give you an arrival window.
