Gaggenau built-in refrigerator repair in San Francisco
Problem: A customer in San Francisco has a Gaggenau RB492701, a built-in refrigerator with a freezer drawer at the bottom, behind deep green panels. They wrote to us because the ice maker wasn’t working.
Diagnostics: Inside the freezer, thick white frost had built up above the food containers and ran down behind them. Our technician found the buildup around the evaporator area and evaluated the defrost system. That system melts frost off the evaporator every so often. Frost this heavy pointed to a defrost malfunction, and it was cutting the airflow. We also found door-sealing problems. A bad seal lets in damp air, and damp air can add to frost.
Solution: We replaced the defrost heating element and the defrost temperature sensors, and put a new gasket on the refrigerator door. A full manual defrost cleared the ice. Then we cleaned and flushed the drain line, and cleaned the coil areas and the airflow passages we could reach. We went through the wiring and connectors too. Once it was back together, we checked the fan, the heater, the drainage and the door seal. Then we confirmed the temperature was recovering and the unit was cooling.
Result: The ice is gone, the drain runs and the door seals. If frost keeps coming back in a built-in freezer, a manual defrost only buys you time. Have the defrost heater, the sensors and the door seal checked too.
