the fan I'm guessing operates off a fan contactor or fan relay. there is an operating coil that keeps the contacts closed. if the operating coil got fried while the contacts were closed, mechanically they'd stay closed. the contacts could have welded together closed. if when you shut off the breaker for the fan you notice the contacts did not open then suspect welded contacts.
