Sub Zero Refrigerator door not opening/closing properly
If your Sub Zero refrigerator door is not closing properly or the fridge door will not seal, the most likely culprit is a twisted or worn door gasket. Inspect the gasket for kinks, tears, or gaps and try smoothing minor wrinkles with a hair dryer; replace the gasket if it is damaged. If the gasket looks fine, check the door catch or cam next since a worn or broken cam can prevent the door from latching. A sagging door that drags or leaves a gap usually points to a bent bottom hinge, followed by a damaged top hinge or a bad hinge kit. On French-door models a misaligned door support or mullion heater flap can keep the doors from closing fully. Inspect each part for play, cracks, or corrosion, and replace worn components to restore a proper seal.
