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 · RefrigeratorCheck settings, vent placement, room temperature and the ice-maker-without-water condition first. If those are fine, suspect a damper stuck open or a sensor reading warm.
Component test · RefrigeratorInverter boards make variable-frequency 3-phase power for the compressor. Electrical checks of the board and compressor terminals are allowed; anything that opens the sealed refrigerant system is EPA 608 work and blocked. Boards fail more often than compressors.
