What Can the Homeowner Do?
If you have noticed any of the trouble signs, have a qualified electrician determine whether the problem is caused by deteriorating aluminum connections. DO NOT TRY TO DO THIS YOURSELF!
You could be electrocuted or you could make the connections worse by disturbing them. If you are not certain whether your home has aluminum wiring, you may be able to tell by looking at the markings on the surface of the electric cables that are visible in unfinished basements, attics or garages. Aluminum wiring will have “AL” or “Aluminum” marked every few feet along the length of the cable.
