We performed a comprehensive diagnostic and repair service on a dual-zone wine cooler in Clermont. Our team identified a failure in the electronic control system and significant ice buildup on the internal evaporator coils. We disassembled the rear access panels and internal housing to reach the damaged components and restore proper thermal regulation. We replaced the faulty circuit board and wiring harness to ensure reliable communication between the dual cooling zones. After manual defrosting and cleaning the evaporator assembly, we verified the functionality of the internal circulation fans and the compressor system. The unit was reassembled and tested under power, successfully maintaining temperatures across both storage compartments.
