Yesterday I found the diode room AC unit without power, and according to trends it had been down since 3/5. The electrical box outside the LVEA, near the outdoor units, was off and the pull tab (gives units power) was found ~10 feet away. This occured during a high wind storm, so it's possible a strong gust of wind threw something at the box. With everything back in place, the room cooled down from 86F to 70F in about an hour. The diodes do not seem to have been affected by this.

The environmental monitoring system is currently down, which is why the diode room temperature has dropped to zero.
