Follow these steps to find the cause of your electrical problem.
A plug-in appliance doesn't work
1. If a plug-in light doesn't work, try changing the bulb. For any other kind of appliance, first try plugging it into another socket. If it works, the original socket could be faulty and need replacing. If it doesn't, try again on a different power circuit (probably on another floor). If it works there, you might have a dead circuit.
2. If the appliance doesn't work in a socket you know is functioning, check the flex connections in the plug and replace the fuse - making sure it has the correct rating.
3. Still not working? The appliance may have an internal fault which needs some professional attention.
A Circuit is dead
1. Turn off all the lights or unplug all the appliances on the affected circuit. Turn off the main isolating switch at the consumer unit, and repair the circuit fuse or reset the circuit breaker or RCD. Then turn the main switch back on.
2. Switch on each light or plug in each appliance in turn to find out which item on the circuit is causing the fuse to blow or the circuit breaker to trip. When you find it, isolate the circuit again and check the fuse, the connections and the flex (see above).
3. If the fuse blows or the circuit breaker trips again, the fault may lie in the fixed wiring. Call a qualified electrician.
