A control condition on this make that clears there and stays clear was a supply interruption, and this coast produces those every afternoon in the summer. ### The step worth taking before you call A genuine five-minute power interruption at the breaker is the dividing line for control conditions on this make. What clears there was the supply. What survives it is hardware. Doing that before booking costs nothing and it changes the conversation entirely. ### Why storms matter here Afternoon storms, brownouts and momentary interruptions are ordinary in this city between June and October, and a board caught mid-write during one produces exactly this.

It is a real condition rather than a supply problem, and it is worth booking. It ranges more widely than most pages here — from nothing at all if it is the supply, to a control board if it is not.
