Sub-Zero CL3650U 36-inch over-and-under refrigerator freezer repair
The CL3650U is the 36-inch Classic over-and-under: 84 inches tall, 20.8 cubic feet, with the freezer on the bottom and an automatic ice maker. It normally goes into a built-in opening, flush with the cabinets beside it.
Because it is still a current model, the problems we see are mostly about use rather than years. Frost in the freezer is the one we chase most: we look at the defrost cycle, the drain, and how well the door is closing. When the ice maker slows down we begin at the water supply and its filter, and after that the mold and its heater.
If the cabinet warms up by afternoon, the condenser airflow is next on our list. If the job turns out bigger than a quick fix, we explain the options plainly and let you decide before work begins. After the work, we run the unit through a cycle and confirm the temperatures hold before we leave.
Frost usually means moist air is getting in or the defrost system is not clearing the coil. We check the gasket, the drain, and the defrost parts, and quote the repair in writing before starting.
Cloudy or small cubes usually point to a restricted water supply, an overdue filter, or a mold heater that is not cycling properly. We trace the water path first because that fixes most ice complaints without touching cooling parts.
A small swing is normal with heavy door use. A steady afternoon climb is not, and it generally traces to a worn seal or dust on the condenser. We inspect both and back the repair with a 30-day warranty.
Book in about a minute, or call the desk. Same-day windows inside the Loop on most days, next-day across the rest of Houston.
