I wrote on this topic earlier, but placed it in the wrong category. It should have been put in this one. The thread is here.
I also wanted to ask about suggestions about an outlet with 2 plug options which no longer works. It just went out one time, and I saw nothing out of place. It just happened one day. Is there anything simple or "simple" I can check on my own, or is this an electrician job? How much should I expect to pay approximately for such a fix? Thank you.
