I have 2 outside recepticles - all of a sudden both stopped working - tested them using both radio and hand mixer - no good. No tripped breakers - even reset them just in case - no good. Just does not make sense - why and what are the chances they'd both go at the same time. One is in back of house - other opposite of side - so probably not on same breaker. Help!! Xmas lights MUST be lit!! LOL...

Assuming your house is relatively new, my guess would be a tripped GFCI (http://www.lakewoodconferences.com/direct/dbimage/50193636/GFCI_Receptacle.jpg). The trick is finding where it is. It could be in a kitchen or bathroom, or in the garage. I had this happen to me, and I finally found it in a half-bath that was near the garage.

Once you find the GFCI, just press the reset button.

Hope this helps,
