i have several areas n my house that where we've been experiencing loss of power lately. when the power goes out, i check the breaker, but it hasn't been tripped. i usually shut it off and turn it back on just to be sure but it doesn't help. the power comes back on when it wants too until this last time. we've been out of power in parts of the house for over 12 hours now including the fridge and heater. does anyone have any ideas? i can't see any signs of charred wires in the breaker box or the few outlets i've checked. i've checked the attic for signs of chewed wires, but nothing there either. any ideas?
