A residential refrigerator can suddenly stop cooling properly due to several common mechanical or airflow obstructions. The most frequent cause is frosted-over evaporator coils hidden behind the freezer back panel, which happens when the automatic defrost heater, timer, or defrost thermostat fails, blocking cold air from circulating into the fresh food compartment. Other common culprits include thick dust buildup insulating the condenser coils beneath the unit, a failed evaporator fan motor that stops blowing air, or a broken start relay on the compressor. You can troubleshoot by inspecting freezer frost buildup and listening for fan noise. You can verify that your corrective action is successful when cleaning condenser coils, replacing faulty defrost components, or thawing iced coils restores cold storage temperatures.
