The Website For Troubleshooting Home Electrical Problems

Solve Home Electrical Problems Yourself!

Does your home have:                        Site Map
  • Electrical outlets not working or ...
  • An outage from a circuit breaker tripping or ...
  • Several lights that blink strangely or ...
  • Receptacles dead because a tripping GFCI won't reset...
  • Or three-way switches having trouble?
For diagnosis of home electrical problems, ever wish you had a house wiring diagram, or reliable online or phone advice?... I am Larry Dimock, The Circuit Detective, a master electrician in Washington state who has concentrated on troubleshooting home electrical problems. Now that I'm semi-retired, do-it-yourself minded people nationwide are getting help to find and fix these problems from me and my did-it-myself website. Disclaimer

Decide how you will use this site:
  • "I don't want to learn so much stuff myself, just enough to see if I can fix this one problem..." You are in luck! I make myself available to help you by E-mail or Phone.
  • "I may have a common or simple problem that might be answered quickly in a FAQs format, or with a little guidance from a Diagnostic tree."
  • "I need to understand my electrical system better first"... Then go study the Background page and diagrams.
  • "I know enough about breakers, outlets, and circuits, but I need tips on troubleshooting and testing"... Then go to the Troubleshooting page for step-by-step help to find the cause of your problem.
  • "I've tried myself, but now I just need an expert to review my problem and give me a fresh approach to it"... Good. I'm generally available 14/6 (really!) to help by E-mail or Phone.

-th visitor since April 2005, welcome! What if this site ever becomes unavailable? Electrical book for the handyman and handywomanOr what if your computer circuit is a victim of your next little outage? You'll be glad to know that all this electrical advice is now available as a book (or download) called Circuit Down. Give yourself, or a DIY-er you know, the gift of Detective Larry's experience and his 35 diagrams and charts. Available online from Lulu, Amazon, and Barnes & Noble.

Tip of the Day: Congress says that by 2014 normal 40-100 watt incandescent light bulbs must no longer be made (to encourage the more efficient fluorescent bulbs). Remember when your dimmer switches were promoted as saving energy? Guess what? Those dimmers are not able to get along with most fluorescent bulbs! You may be going back to regular on-off switches. - Detective Larry     ...More Tips of the Day.

The Scope of This Website: These pages have been designed for the U.S. or Canadian DIY homeowner who faces home electrical problems, that is, electric malfunction issues in his/her household electrical wiring system. The site is not oriented to helping with design, installation, or with remodel projects. [More geared to these are such sites as this well-written one and electrical-online; but I would avoid ehow.com as unreliable based on this page, where for three years they have been advising wrong and dangerous ways to test outlets.] Some books are better at wiring projects than most websites.
The concept is Home Electrical Troubleshooting:
1. "Home" includes any residence: a house, condominium, apartment, or mobile home.
2. "Electrical" - meaning the alternating-current house wiring system, from power company equipment, through circuit breakers or fuses, to plug-in outlets, electrical switches, and some of the appliances and fixtures operated by this current.
3. "Troubleshooting" here means the process of investigating and fixing home electrical problems; the site is not concerned with upgrading or preventive maintenance, except as these activities may result in a new problem.

Some who need to find this site's material may be searching with terms found in this statement: "When I replaced a toggle two way switch with a rocker tree way switch, the GFI breaker switch wall socket popped off. I guess I need help to trouble shoot my house hold electricity. Cant a GFCI circuit or GFI switch handle a 3 way circuit? I don't want any wall outlets to go bad or get dim from a bad breaker. I want a free electrical advice website and to learn home electrical repair."

Beginners' Corner -
An outlet with a reset button is usually sensing faults at other normal outlets too, and will make them go dead too when it trips off.

Advanced Corner -
If you are slightly live (from a fault in a heated floor, say), then anything grounded that you test with a neon or non-contact tester may register as if those things were what is live.
