As a service to our valued customers, we are happy to provide tips on handling common electrical problems. These don’t necessarily require a service call by an electrician.
- There is a short circuit.
- There is an overloaded circuit.
- The circuit breaker is broken.
Short circuits occur when two electrical wires accidentally touch each other. A short circuit will immediately cause one of your circuit breakers to trip off or one of your fuses to blow.
To fix a short circuit, ask yourself this question: “What was happening right before the short circuit?” If you had just plugged something into a receptacle (outlet) or turned on a light or an appliance, then this gives you a clue as to what caused the short.
If you just plugged in an iron, for instance, you can simply un-plug the iron and then re-set the circuit breaker or replace the fuse. If everything is now OK, then your electrical system is fine – and it’s time to get a new iron!
If, however, you can’t find anything plugged in which is causing the problem, then it’s time to call a good electrician to locate and repair your short circuit.
Overloaded circuits occur when too much power is running through an electrical wire. To protect the wire, the circuit breaker does its job by detecting the overload and tripping off. The solution to this problem is to remove some of the appliances that are connected to the overloaded wires. You may wish to add a new set of wires so that you can supply power to all your appliances. For this, you’ll need a good electrician.
Broken Circuit Breaker
Sometimes circuit breakers just wear out and need to be replaced. A knowledgeable homeowner with electrical skills can do the job. Otherwise, hire a good electrician.
Resetting Circuit Breakers
The first thing to understand is that a circuit breaker can have tripped off even when it looks like it’s in the “ON” position. This is because a circuit breaker will sometimes trip off internally, without the “ON/OFF” handle flipping to the “OFF” position.
This is what to do when you have a loss of power that you suspect may be caused by a tripped circuit breaker.
- Shut down any computer equipment that may be affected by a loss of power.
- Go to your circuit breaker panel and firmly flip the first breaker OFF and then back ON again.
- Do the same thing with each circuit breaker until you have flipped all of the circuit breakers OFF and then back ON again.
- Now check and see whether the device that didn’t have power is now back on again.
- If your power has been restored, you’re done! If your power is still out, it’s time to call an electrician.
- Note: About 25% of all electrical power problems can be solved using the above technique. Good Luck!
However, if a dimmer is REALLY warm or hot to the touch, this indicates a safety problem, and you should call an electrician who is knowledgeable about lighting issues
- Dimmer Warning – Two things to be careful about with dimmers:
- Never connect a regular dimmer to low-voltage lights, paddle fans, or any kind or motor. These devices require special dimmers.
Never exceed the recommended wattage of the dimmer. Regular dimmers are rated for a maximum of 600 Watts. This is equal to 10 sixty-Watt light bulbs, or 6 one hundred Watt bulbs.
NOTE: You can also buy higher-wattage dimmers for connecting more than 600 Watts to one dimmer.
When the top of the fuses is made of glass, many people think that they can look at the metal piece inside and see if it is broken. THIS IS NOT ALWAYS TRUE.
The best way to handle a suspected blown fuse is to simply replace it. If the power comes back on, great! If it doesn’t, then you should call an electrician who is good at troubleshooting.
The idea of a GFI receptacle is that if there is the slightest electrical problem, the (ground fault interrupters) GFI immediately shuts off the power. This is an important safety feature.
When you lose power to a receptacle in a kitchen, bathroom, garage, or outdoor area, check to see if it’s a GFI receptacle. If it is, press the “TEST” button, then press the “RESET” button. If the GFI shuts off power repeatedly, plug in a different appliance to test whether the problem is the first appliance or the GFI itself. If the GFI is defective, call a good electrician.
Hint: You may have a receptacle that has lost power in a kitchen, bathroom, garage, or outdoor area but it’s not a GFI. It may be “protected” by a GFI that has tripped off somewhere else. You can check for this situation by making sure that all the GFIs in your kitchen, bathroom, garage, and outdoor areas are working properly.
Lights don’t turn on for the below basic reasons:
- The bulb is bad. This is more common than one might think. Try replacing a questionable light bulb with a new one. If that doesn’t work, before giving up, try using a bulb from another light fixture that you KNOW is working.
- The switch to the light is bad. The switch will need to be replaced.
- The light fixture is broken. Usually it is easiest and least expensive to simply replace the fixture. However, many light fixtures can be repaired if it is desired.
- No power.
- The time clock for the light is not set for the correct time or is broken. Re-set the time or replace the broken time clock.
- If the light fixture is activated by a photo-cell, the photo-cell is out of adjustment or broken. Adjust or replace the photo-cell.
- Fluorescent, Mercury-Vapor, or High-Pressure-Sodium Lights. These kinds of light fixtures all use an electrical ballast to energize their special light bulbs. If the light is humming loudly or has an “electrical odor,” or if the light just doesn’t turn on, the ballast may need to be replaced.
Lights Not Turning Off
- The switch to the light fixture is broken. Replace the switch.
- The time clock for the light is broken or out of adjustment. Set the time clock to the right time. If it won’t stay adjusted, replace the time clock.
- If the light fixture is activated by a photo-cell, the photo-cell is either out of adjustment or broken. Adjust or replace the photo-cell.
Lights Blinking On And Off
There are two main reasons for lights blinking on and off:
- A photo-cell is out of adjustment. Adjust the photo-cell.
- Some light fixtures that are recessed into the ceiling have a built-in thermal protector that automatically shuts off the light when the fixture gets too hot. Use a lower wattage bulb for a lower temperature.
Flickering Fluorescent Lights
There are three reasons fluorescent lights flicker:
- For a few moments when they first turn on, the bulbs will flicker until they warm up. You will notice this more on colder days. Just wait a few moments for the bulbs to warm up.
- The fluorescent bulbs are old. Replace them.
- The fluorescent ballast is old. Replace it.
Bulbs Burning Out Too Quickly
Here are the three reasons bulbs can burn out quickly:
- The wattage of the bulb is too high. This is very common. Most light fixtures with glass covers have a maximum rating of 60 watts per bulb. It is very common for people to put in 75 watt or even 100 watt bulbs. The result is bulbs burning out much too quickly. Use the correct wattage bulbs in all your light fixtures.
- Poor-quality lights bulbs. Use only major-brand light bulbs.
- Mysterious light fixture problems. It’s mysterious because the light fixture LOOKS perfectly fine, and even electricians can’t find anything wrong with it. Nevertheless, after checking #1 and #2 above, if the bulbs keep burning out,replace the light fixture.
Humming lights can be caused by:
- A bad ballast or bad transformer. Replace the ballast or transformer.
- A conflict between a low-voltage dimmer and the low-voltage light fixture it controls. This is a tough one, but sometimes experimenting with different dimmers will lead you to one that doesn’t make the low-voltage light transformer hum.
Lights will sometimes dim for a few seconds and then come back to complete brightness again. This can happen when a light is connected to the same wires that provide power to an appliance that takes a lot of power, like a refrigerator, a microwave oven, or an air conditioner. The reason the light dims for a few seconds is that the appliance is using a lot of power when it first starts up. After the appliance is running for a few seconds, it will use less power, and the light will return to normal again. If you have central air-conditioning, the lights may dim each time the air conditioning comes on.
You will usually notice this dimming more at night (for obvious reasons!), but you might also notice it in the daytime. If this dimming bothers you, you can handle the problem by having an electrician add another circuit specifically for the appliance that is causing the dimming problem.
NOTE: If you haven’t changed anything electrical in your home or office, and you suddenly start to have dimming problems or power fluctuations, then you probably have a loose wire somewhere. You should contact an electrician skilled in troubleshooting to find and correct this problem.
