Sub-Zero Refrigerator Repair in Davis Islands, Tampa: Dead After a Lightning Strike

Built-in Sub-Zero refrigerator in a kitchen in Davis Islands, Tampa
Symptom
Only the interior light worked — no compressor, fans, or display — after a lightning strike.
Cause
Control board damaged by the power surge.
Fix
Installed a factory-ordered control board (a two-day wait for the part).

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.

Tracing a surge to the control board

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

A factory-ordered part

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.
