Sub-Zero refrigerator out of warranty — repair is still the right first call —
a fridge running warm, a freezer icing over, frost on the back wall — out-of-warranty refrigerator faults look critical and almost never are. Thermostats, fan motors, defrost systems and door seals are replaceable components. The machine is almost always worth repairing, fridge-freezer combo, side-by-side, French door or built-in.
