We bought a new one and when my husband removed the base of the old one and reached in to connect the new one, the lights in an adjoining room flickered. (I sure thought he ought to have the juice off to the whole house, but he said "no," he just needed to turn it off to the kitchen.)
He says this is a sign we need to get an electrician to check the wiring.
What say you?
[Yes, yes, we know nothing, but at least I know enough to ask you. One possibility is to have Lowes come install it as that is where we bought it. But I wanted to get your take on it first as you have been so helpful in the past. I was thinking, through the breaker for the whole house, hook it up, and see what happens. No?]
