These compact units still need the ventilation clearance Sub-Zero specifies at the grille, and that’s often the first thing lost when a kitchen gets refitted around one. A unit that’s been running hot for a year usually needs a condenser service before it needs anything else — airflow, not a failing compressor, is the most common root cause we find.
Drawer seals and runners affect temperature as much as they affect how the drawer feels to use, and a unit installed under a bar sink is worth checking at the first sign of dampness — a slow leak reaches the compartment well before it shows up as a puddle on the floor.
