Dispatched our San Bernardino County refrigeration technician to a restaurant reporting issues with their walk in systems. Upon arrival, found unit #1's evaporator and condenser working fine, walk in #1 had no issues. Walk-in #2 had an iced over evaporator coil which our tech defrosted. Determined that the breaker for the condenser fan motor had be shut off. Reset and determined all other operations normal.
