Thermador Refrigerator

Thermador KBUDT4265E

Model # KBUDT4265E

The KBUDT4265E is the 42-inch KBU side-by-side supplied with Thermador’s own door fronts rather than custom panels. It shares its manual and electronic control generation with the KBUIT4265E and with the 48-inch KBUDT4865E.

On a side-by-side this old, a freezer that warms while the fresh-food side stays cool usually traces to frost on the evaporator or a stopped fan, since fresh-food cooling depends on air from the freezer. A compressor that clicks and will not start is a separate problem, often in its start parts rather than the compressor itself.

FAQ

Thermador KBUDT4265E FAQ

On side-by-side designs the freezer side often shows airflow and defrost problems first, so the evaporator and fan are checked before the compressor.

Not necessarily; a failing start relay causes exactly that pattern and is a much smaller repair.
