The short answer
On the Bertazzoni URBCD refrigerator a cabinet that stays warm while the unit is plainly running is almost never a dead compressor. On this family it is an airflow fault first — a defrost cycle that has stalled and let the evaporator ice over — and a control or sensor fault second. The brand-generic article ranks the sealed system higher than it belongs here.
What an owner actually sees
- The fresh-food side warms before the freezer does — On a single-evaporator cabinet the fresh-food compartment is fed last, so it fails first.
- The run never ends — The compressor no longer cycles off, because the control never sees the setpoint reached.
- Condensation or soft ice cream in the freezer — The freezer is losing ground too, just more slowly than the fresh-food side. A freezer holds food safely at 0 °F (−18 °C) or below.
- NEAR MISS — the cabinet is silent and nothing is cold — No hum, no fan, no light behind the controls means a supply, start-relay or main-board fault, and that is a different page.
What it usually turns out to be, in order
- Frosted evaporator from a stalled defrost cycle — First on this family, and the reason the whole order is what it is.
- Evaporator fan motor stopped or dragging — Second because it produces the identical warm cabinet with none of the frost to show for it, and because on the URBCD cabinet the fan is behind the same panel as the evaporator — one teardown answers both.
- Condenser coil blinded by dust or pet hair, or a stopped condenser fan — Third. It degrades capacity rather than removing it, so the cabinet drifts warm slowly and recovers badly after every door opening.
- Thermistor or control board reporting a temperature the cabinet does not have — Fourth.
Check in this order, and why
- 1. Open the freezer and listen for the evaporator fan — Hold the door switch closed by hand.
- 2. Look at the freezer rear panel for frost — If the fan runs and there is a frost sheet, the defrost system is your fault.
- 3. Pull the unit out and check the condenser coil and its fan — Dust-blinded coils and a stalled condenser fan are both visible without a meter, and both are cheap.

Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. The freezer rear panel on this family sits over the evaporator fan and often over a defrost heater, so treat both as live until the plug is out of the wall, and never hold the door switch closed with tape while your hands are inside the compartment.

Owner fix or service call
Call once the two freezer-side checks and the condenser check are clean, because what is left is sensor and control work that needs a meter and a wiring diagram. Call immediately, without further testing, if you smell burning, see oil outside the tubing at the compressor, or the cabinet is warm and the compressor is hot and silent — all three point at the sealed system or the compressor itself, where the tools and the licence stop being owner tools. On this family the practical line is the freezer rear panel: what is in front of it is yours, what is behind it usually is not.
