I was an Electrician in my prior life (before I took the managment job) first..go to your panel an reset the breakers..they should snap back firmly..Cycle the breakers about 3 times...if 1 reset feels"mushy" that could be your problem...next go into your garage...many houses will have a GFI in the garage as the first recep before the circuit continues into the house..go and TRIP it and then reset...same thing for the bathroom recp...trip then reset...kitcken counters usually have 2 circuits....should be GFI close to the sink...if you still can't find it..pm me we'll get on the phone and go from there...Eddie

BTW..most Kitchen and appliance circuits are 20 amp...rest of circuits are 15 amp...
