Guide · RefrigeratorAn adaptive defrost board replaces the old cam timer. It counts compressor run time (and on some boards door-open time) and adjusts the next defrost interval based on how long the last one took. Test the heater and the cold bimetal first, then force a defrost: if the heater warms on a forced defrost but the coil still ices, the board isn't starting defrost on its own.
Guide · RefrigeratorThe hinged flipper on one fresh-food door seals the gap between the doors and has a small heater inside to keep it from sweating. Problems are either mechanical (flipper loose, broken, or not riding on its guide) or electrical (heater open). Check the mechanics and the guide on the cabinet first, then test the heater.
Guide · RefrigeratorOn Samsung French-door refrigerators with a separate fresh-food evaporator (for example RF28 and RF263 families), owners and repair sites widely report ice building on the fresh-food evaporator until it blocks airflow or strikes the fan. Causes reported include incomplete defrost, a weak defrost heater and an off-calibration defrost sensor. We found no Samsung service bulletin or recall for it, so treat it as a known field pattern, not a manufacturer-acknowledged defect.
