KitchenAid french door refrigerator defrost repair in Santa Clara
Problem: A KitchenAid french door refrigerator (model KRFF305ESS) in Santa Clara was not holding temperature. In this design the freezer evaporator cools both compartments, so when the defrost system stops working, frost keeps building until airflow is choked off and the fresh food section warms up.
Diagnostics: Our technician pulled the freezer back panel and found the evaporator coil encased in frost from end to end. Frost this heavy means the defrost cycle has not been running, and the inspection settled on the defrost bi-metal thermostat mounted on the evaporator as the component to replace.
Solution: We safely thawed and cleared the evaporator coil, replaced the failed defrost bi-metal thermostat, and confirmed the defrost circuit and evaporator fan were working before putting the panel back.
Result: The refrigerator is cooling normally again in both compartments. With the defrost cycle restored, the coil stays clear on its own and the repair addressed the cause, not just the symptom.
