Master Bedroom lost power -- bad breaker?
Around 3pm on Wednesday my master bedroom and bath lost electricity. According to my wife, she wasn't doing anything at the time (electricity-wise). I checked the panel and everything was on. I re-flipped all the circuits but still no power. Could it be a bad breaker? We were experiencing frigid temperatures at the time (high of 0F), but no frozen pipes. The house is 37 years old. Any advice is appreciated.
