General Advice

  • Get as much information about the problem as you can.
  • If an electrical socket is not working is it just the one socket not working or are no electrical sockets working? Are all ceiling lights not working or just one?
  • If a boiler is not working, do the TV and tumble-dryer work? Have all supplies, to the house, been lost, or just to one circuit or one appliance?
  • Is the problem something that is happening regularly? Is there a history of electrical problems in this room, on this circuit or in this house?
  • Is it always the same bulb, fuse or RCD (Residual Current Device) that blows?
  • Always check RCDs even if you think the RCD is not the problem.
  • If in any doubt please contact BRH Electrical for free advice.

RCD (Residual Current Device) Has Tripped And Won’t Reset

  • The problem in almost never the RCD; the problem will be an appliance causing the RCD to trip.
  • Unplug all electrical appliances, for instance TVs and kettles – does the RCD reset now? If yes, one of the appliances is at fault; if no, call a qualified electrician.
  • If the RCD resets after unplugging all the electrical appliances, plug each appliance back in, one at a time, to find out which appliance is causing the problem.

Electric Or Gas Boiler Not Working

  • Check the fuse, gas boilers sometimes have electrical supplies, the fuse will be near the boiler or on the main fuse board.
  • If replacing the fuse does not solve the problem call an electrician or gas engineer.

Free-Standing (Table Or Floor) Lamp Not Working

  • Replace the bulb.
  • If replacing the bulb does not work remove the supply to the lamp and clean the inside of the bulb holder – scrape with a knife or screwdriver. The bulb holder often becomes ‘oxidised’ (Black in colour); this prevents good electrical contact between the bulb and bulb holder.
  • Is the power cable in good condition? Has it been damaged?
  • Table and floor lamp troubleshooting tips.

Recessed Light (‘Down Light’) Problems

  • Recessed lights (down lights) use many different voltages. Is the bulb voltage rating correct? Compare the problem bulb, or bulbs, with bulbs that work OK – are they the same?
  • Recessed lights (down lights) have many different wattage ratings. Is the bulb wattage rating correct? Compare the problem bulb, or bulbs, with bulbs that work OK – are they the same?
  • Is something covering the bulb housing, for instance loft insulation? Overheating causes many different problems.
  • Home lighting troubleshooting tips

Ceiling Light Not Working

  • Replace the bulb.
  • Many ceiling lights have transformers to change the input voltage to the bulb, this may be causing the problem. The transformer will be in the ceiling space or loft.
  • The problem could also be the wiring to the bulb holder – wiring securely connected? Good state of repair?
  • Home Lighting Troubleshooting Tips
  • Downlight transformers

 

Lights Flickering

  • Usually a poor electrical connection.
  • If one light or bulb check the wiring to the light or bulb (bulb holder); wiring securely connected? Good state of repair?
  • If one light or bulb check the wiring to the switch; securely connected? Good state of repair?
  • If more than one light or bulb check the RCDs
  • If more than one light or bulb call a qualified electrician; the problem is likely to be at the RCD panel or in the earth or neutral line (poor wiring).
  • Home lighting troubleshooting tips

Recessed Light (‘Down Light’) Stops Working But Later Starts Working

  • Probably the electrical safety ‘cut-out’ operating.
  • Usually due to overheating. Is something covering bulb housing, for instance loft insulation? Incorrect bulb wattage – what wattage are the other bulbs, is the problem light the same wattage?
  • Home lighting troubleshooting tips

One Light Is Brighter Or Dimmer Than The Others

  • The obvious – are the bulbs the same wattage?
  • Poor wiring to the bulb holder – wiring securely connected? Good state of repair?
  • Home lighting troubleshooting tips.

One Bulb Blows More Often Than Others

  • Bulb wattage – is the bulb correct wattage, what wattage are the bulbs that don’t blow so often?
  • Poor wiring to the bulb holder – wiring securely connected? Good state of repair?
  • Home lighting troubleshooting tips.

Electrical Socket Not Working

  • Are all electrical sockets not working or just the one?
  • If no electrical sockets are working has an RCD tripped of a fuse blown? Check fuses. Check the RCDs.
  • The problem could also be the wiring to the electrical socket – wiring securely connected? Good state of repair?
  • Is the switch in a good state of repair? Does the socket look damaged? Does the socket look discoloured? Replace the electrical socket if the socket is in a poor state of repair.

 

 Tumble Dryers

  • Not working at all. Is the supply to the tumble-dryer OK? Plug another appliance into the electrical outlet – does this appliance work? If the tumble-dryer does not have a plug but is ‘hard-wired’ (flex outlet) into a supply there will usually be a small light in the surround of the supply outlet at the wall – is the light on? Is there a fuse – has the fuse blown?
  • No hot air (not hot). Has the tumble-dryer overheat switch tripped? This often happens if you stop the tumble-dryer before the ‘cool air’ part at the end of the cycle (Usually the last 10 minutes or so). There is usually a reset button on the back of the tumble-dryer.
