Sub-Zero BI-42S Built-In 42-inch Refrigerator Freezer Service
Most BI-42S cabinets sit flush in a run of cabinetry, either wearing a custom panel or showing stainless. This classic 42-inch built-in holds 16.3 cu. ft. and gives the fresh-food and freezer sides a compressor each, so a cooling problem on one side often leaves the other untouched.
Because production ended and many are a decade or two old, we expect gasket wear. Two codes turn up on this model: 40/1/40, which flags excessive compressor runtime, and 10/R/01, which points to a shorted evaporator thermistor. The gasket is the usual cause of the first, so we test the seal before blaming the compressor. Also sold as ICBBI-42S.
Pricing is written and approved by you before we start. If a part is needed, you hear about it before we order it.
That code reports excessive compressor runtime. On a cabinet this old, we start by checking how well the door gaskets seal, since a weak seal keeps the compressor running without any real compressor trouble.
No. It points to a shorted evaporator thermistor, the sensor that reports coil temperature to the control. We test it and replace it as a single part, without opening the sealed system.
Yes, because each side has its own compressor. That separation is why we diagnose the cold side and the warm side independently instead of treating the cabinet as one unit.
