Sorry for the minor and, hopefully simple problem being posted but I would appreciate any help as I am not knowledgeable about this stuff. I have a series of about six outlets under the cabinets in my kitchen. Some time after breakfast they all stopped working. When I checked downstairs the breaker had been tripped so first I switched it to on which did not work so I switched it all the way off then back on again (I've done this several times now) and still nothing. There is one outlet with the GFCI buttons but when I press either they don't go down so I assume something else is the culprit. Any ideas of what I can try next?
