What the BUC family is
The Black Decker BUC freezer code covers the models in the variant table below, and BUC is a broad code rather than one design. On this platform not holding temperature is what arrives most often, with water in the base or on the floor behind it; the others are occasional rather than routine.
The problems that happen on these models
- Not holding temperature — Contents softening at the top, heavy frost on the walls, or a cabinet that has stopped cooling while it still runs. Covered in full on the BUC page. — Slug: black-decker-black-decker-freezer-buc-freezer-cooling-failure — Title: Black Decker BUC Freezer: Not Cooling or Not Freezing
- Water in the base or on the floor — Meltwater standing in the bottom, a puddle at the front, or beads across the walls. Covered in full on the BUC page. — Slug: black-decker-black-decker-freezer-buc-freezer-water-leak — Title: Black Decker BUC Freezer: Water Leak
- Noise or vibration — A hum carried through the floor, a rattle tied to the compressor, or a whine that rises with running time. Covered in full on the BUC page. — Slug: black-decker-black-decker-freezer-buc-freezer-abnormal-noise — Title: Black Decker BUC Freezer: Abnormal Noise or Vibration
Problem classes, most frequent first on this family
- Not holding temperature — The dominant class here, and the one with a deadline: the contents outvalue most repairs.
- Water in the base or on the floor — Second, and nearly always the drain outlet or the seal, not anything mechanical.
- Noise or vibration — Third, mostly levelling and contact: only a steady rising whine is a part failing.

Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Never chip ice away with a blade: the tubing behind it is thin-walled, and a puncture ends the appliance.
When to call a technician
Owner work here covers seals, frost, drains, clearance and levelling. Call once they are clear, and immediately for a compressor that clicks in and out every few minutes or a coil that never becomes warm — then move the contents, because a freezer holds food safely at 0 °F (−18 °C) or below.
