Door lock light flashes, I

Power interuptions are never good. If all your controls work and the door wont lock you are going to want to replace the door switch or latch whatever your manufacture calls it. Unplug it wait fifteen minutes (make sure door is shut) plug it back in (also reset breaker is cant unplug) if this dont fix it, either a control board short, easiest and cheaper repair is door switch/latch
