I moved in to a new place a couple months ago. The bottom plug on all three (2-plug) power outlets along the kitchen counter tops do not work. We checked all of the breakers in the basement.
I borrowed a 3-LED circuit tester. The green LEDs light up to indicate the top plugs are correct but no LEDs light up on the bottom plugs. The instructions say this indicates "open hot" but it is the same code as when it's not plugged in to anything. I have not taken the cover plate or outlet out of the wall yet.
A friend recommended replacing the outlets themselves. I'm willing to try it but I'm a bit skeptical. I think the problem lies elsewhere because all three outlets have the same problem. Or maybe someone blew all three in a row when they moved some broken appliance around.
Maybe the bottom plugs are wired on their own circuit. Would it be reasonable to split the wires to the top plug to go to both plugs in parallel?
Any ideas about what I should check or do? I live in Canada. We use similar (or the same) circuits as the USA (120 V, 60 HZ). I have a background in electronics (digital and analog) but nothing relating to home wiring.
