The CL4250SD is Sub-Zero’s current-production 42″ Classic side-by-side refrigerator/freezer with a dispenser, with parts and service documentation kept current since it’s still in production.
New fan noise from behind the rear panel, and frost building up inside the freezer compartment, are the cooling issues reported most on a CL4250SD. Separately, a dispenser running slow or dry usually comes down to the fill valve or water line rather than the cooling system.
