CL4250S

Sub-Zero CL4250S 42-inch side-by-side refrigerator repair

Most common issues on this model

  1. Water collecting under the crisper drawers
  2. Cabinet holding cold overnight but warming during the day
  3. Lights inside that stay off or blink with the door

The CL4250S is a 42-inch Classic side-by-side without a dispenser. It usually goes into a built-in opening where its slimmer doors suit a narrower kitchen aisle.

Water under the crisper drawers tops the list on this one. The cause tends to be a clogged drain line or a seal that is letting condensation run where it should not, and ignoring it can lead to ice or odors. We clear the drain, check the seal, and find where the moisture is entering.

A cabinet that warms through the day gets the same inspection of the gasket and condenser airflow. Light problems are usually quick: bulb, socket, or door switch. Quiet, tidy work matters in a finished kitchen, and we leave the area as clean as we found it. If we find something unrelated that deserves attention, we tell you but do nothing without your approval. It is also sold as ICBCL4250S, which is the identical unit under an ICB-prefixed number.

CL4250SCL4250S questions
Why is there water under the crisper drawers of my CL4250S?

Most often the defrost drain is partly blocked, so meltwater overflows into the produce area. We clear the line, check the seal, and confirm the water has a clear path out.

Is it safe to keep using the unit with water pooling?

For a short time, yes, but pooled water can freeze, damage drawers, and encourage mold. We recommend a visit soon, and you will have a written price before any repair begins.

Why does my CL4250S light blink when I open the door?

A blink is normally a loose bulb, a worn socket, or a door switch that is intermittent. We check those parts and offer a 30-day workmanship warranty on the fix.
