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 · RefrigeratorSwings usually come from a frosted evaporator (defrost failing), a sticking damper, or a sensor problem. Check frost first, then damper and thermistor.
Guide · RefrigeratorOn single-evaporator units, cold air comes from the freezer through a damper or duct. A frosted evaporator, a stopped evaporator fan or a stuck damper will starve the fridge side. On dual-evaporator units (many Samsung models), the fridge evaporator, its fan and its defrost circuit are the usual suspects.
