Burned Out Light Bulb

At times, a ceiling fan seems to spark when a light bulb has burnt out.

If your fan has an incandescent light bulb, the filaments fail when a surge of electricity emerges, as a result, it makes a popping sound and a bright flash before it burns out completely. You will be able to notice when a bulb will be burned out due to its popping sound and flash and it does it only once.

If this happens, you have to unscrew the bulb, see the wattage and replace the bulb with a new bulb that comes with the same watts. You need to ensure that you screw the new one firmly but not too tightly, you can flatten the tab in the socket by using a heavy hand that gives energy to the light.

You need to switch off the power to the fan before changing the light bulb to be safe. Turning off the power will keep you safe from the electric shock.

Short Circuit

If you see true sparks coming from the housing of the fan and the light bulb also burns out, there is a great chance that you have a short circuit in the wiring. In this case, the breaker to the room will flip off, in this case, you should leave it as it is until you get professional help.

A short circuit is a result of two wires touching each other that should not, giving a new, shorter path for the power to travel. This new path downgrades the resistance to the flow of electricity, which causes more heat. This production of heat is the reason why a short circuit is called a fire hazard.

It is a professional task to fix a short circuit, as it includes the involvement of complicated electrical work alone. However, if you want to do it, you have to switch off the breaker in the room, take down the fan from the ceiling, and search for the wires that are blackened or melted.

In some cases, the exposed wires will be visible to you because of the falling-off cap which can result in worn wire insulation.

You’ll have to repair the wiring, reassemble the fan, and examine every light bulb socket for damage that may be a result of the short circuit. At times, the heat from the short circuit can fuse the light bulbs into the socket, if that is the case, you should get a professional to come to fix the problem.

Causes of a Short Circuit

Any of the following things can result in short circuits:

  • Old or damaged wire insulation 
  • Loose electrical connections 
  • Household pets such as mice, squirrels, rats
  • Old or broken appliances
  • Outdated wiring (more than 40 years or older, often aluminum)

Generally, when wires get loose or frayed, the danger of a short circuit is increased. If you observe any broken or frayed electrical cord, you need to unplug it immediately so it may not result in a short circuit.

Why Short Circuits Are Dangerous

Short circuits can happen but they are very dangerous. When a short circuit happens, the electrical system of the home has a built-in protective reflex to turn off the breaker to that room. If you see a breaker is flipped off automatically, you should get a professional assistance and leave the breaker as it is.

Consequences of Leaving a Short Circuit Unfixed

If your short circuit remains unfixed, the heat resulting from the shorter path of electricity will build up and spread, more likely to put the house on fire. You need to keep the breaker to that room flipped off if there is a short circuit in your house, call a professional electrician to solve the problem.
