Guide · RefrigeratorStart by knowing the architecture. Sub-Zero built-ins have two separate sealed systems, so a warm section means a fault in that section's own fan, defrost, sensor or system. Monogram built-ins share one freezer evaporator and feed fresh food through a damper, so a warm fresh-food side with a cold freezer points at the damper, airflow or an iced return passage.
Guide · RefrigeratorOn conventional top-mounts, a mechanical defrost timer and a cold control decide when the unit cools or defrosts. Advancing the timer by hand tells you in minutes whether the timer, the defrost parts or the cold control is at fault.
Guide · RefrigeratorSabbath mode disables lights, alarms, dispenser and the panel response while cooling continues. It can be turned on by accident. Exit it with the model's key combination; it may also time out (LG 96 h, Samsung 85 h).
