To AD0AR, you really NEED working GFCI outlets in the kitchen for meeting the code, and especially for your safety. Before doing much else, I would purchase an outlet tester which is probably less than $20 from a box or hardware store. They have 3 lights which show if the hot, neutral, and ground wires are correctly wired. Check all the outlets in your home, it is not uncommon to find something is wrong. This may not solve your problem, but is a good first step. GFCI protection can be with a GFCI breaker in your breaker panel, or with a GFCI outlet in the first outlet after the beaker panel. Pay attention, since the white wires (neutral) should not be connected to the green (ground wire) in your walls and outlets. I have found reversed hot and neutral wires in outlets, and missing ground connections. Not sure if it would contribute to RFI issues. I am not an electrician, so be safe and hire a licensed electrician if you are not comfortable, and check out my and other advice yourself, since any of us could be wrong. KL7CW
