Just use a socket tester and it will tell you if you have a good ground and the wires are all good. First thing my electrician used for me.Our son had the same problem when he got his 700. Contacted RT and they sent him a replacement grill. Same thing with the replacement and he found it needed a complete grounded circuit and the problem went away. I'm thinking that's what the OP is having.
