A built-in Sub-Zero refrigerator in Davis Islands, Tampa went completely dead after a power surge from a lightning strike. The only thing still working was the interior light — no compressor, no fans, no display, nothing else responded at all.

That pattern — everything dead except the light — pointed straight at the control board, and the surge from the lightning strike had taken it out.

This board isn’t something we keep in stock — it had to come directly from the factory, which meant a two-day wait before the repair could be finished.

With the new board installed, the refrigerator powered back up normally — compressor, fans, and display all working again. If your Sub-Zero refrigerator goes completely dead after a storm or power event, a surge-damaged control board is one of the first things worth checking.
