The fire started behind a spare refrigerator in a remodeled room.  The refrigerator was located to the left of the washer (in the right of the photo).   The burn pattern on the wall next to the washer indicates that fire originated near the floor.<br />    The main electrical panel is in the left of the photo.   Note the hole burned through the back of the enclosure.   The intense heat melted the plastic components, resulting in an electrical arc.   This created a second ignition source.
