A row of outlets in my kitchen just stopped working one day. One of them is a gfci. There are 2 other outlets and 2 lights (light switches) on the wall that don't work as well. I checked all my fuses and other gfci in the house. All of them are good. On the gfci that doesn't work, I can't even push in the test button and when I hit reset nothing happens (test doesn't pop out). Do you think I just need to replace the gfci or any idea what the problem might be?
