The short answer
Most Driven compact refrigerators have no display at all — the control is a mechanical thermostat dial, and its printed numbers are relative settings rather than degrees. That single fact resolves a large share of "control fault" complaints on this class. If your unit does carry a display, the ranking below still starts with the supply, because a cabinet on a switched or tripped outlet looks exactly like a dead panel. What you have is a cube-style mini fridge.
What you are seeing
- The display is blank, or lights up and then goes out
- A code or symbol appears that is not explained on the cabinet
- The dial turns but nothing about the cooling changes
- A dial that clicks but produces no cooling at all is a cooling or supply fault, not a control fault — This points at a different fault; the page named above covers it.
Most likely causes on a compact refrigerator, in order
- A mechanical dial being read as a broken control — ranked first because on this class it is genuinely the most common call: the numbers are relative, higher is usually colder, and there is no feedback to confirm a change took effect
- A desk power strip or a switched socket — cube fridges go under desks and in dorm rooms, so they end up on strips that get switched off at night and on leads too thin to carry a compressor start
- Supply problems presenting as control problems — a switched socket, a tripped breaker, an overloaded extension lead or a partially seated plug all produce a dead or flickering panel, and all are faster to check than any board
- A mode that was set deliberately — sabbath, display, demo, eco and child-lock modes exist on units with electronic panels, and each one changes behaviour in a way that reads as a fault to someone who did not set it
What to check, and why in this order
- Trace the whole supply back to a wall outlet before anything else — On this form the lead and the strip are more likely than every appliance cause combined
- Prove the outlet first with something else plugged into it, and check that it is not switched or on a tripped protective device. — Everything below assumes a live, stable supply
- Establish what control the unit actually has by reading the rating plate and the panel — A mechanical dial and an electronic control fail in completely different ways and half of this list applies to only one of them
Step by step
- Plug a lamp or a phone charger into the same outlet and confirm it works. — Time: a minute.
Tools: any known-good appliance
- Trace the cord back to a wall outlet, removing every strip, adapter and switched socket in the path. — Time: several minutes.
- Take a clear photograph of the display and of the rating plate. — Time: a minute.
Tools: a phone
- Turn the dial or set the control through its full range and listen for the compressor to respond at the cold end. — Time: several minutes.
Before you start: safety
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Do not spray any cleaner directly at a control panel or a display — spray a cloth instead. Water behind a membrane causes exactly the intermittent behaviour this page describes, and on a mains appliance it is also an electrical hazard.
When to stop and call a technician
Call for service when the panel stays dark on a proven live outlet, when a code returns immediately after a full power cycle, or when the control reports a sensor fault. A control board on a cabinet this simple is worth diagnosing properly before it is replaced, because most of what looks like a board is not one.

What this page does not cover
This is generalized information: it covers Driven refrigerators as a class, not one family or model. It does not carry your model's error-code table, wiring, part numbers, capacities or ambient range — those are on the rating plate and in the documentation, which are the authority wherever they disagree with this page. It leads with one form, the cube-style mini fridge, and flags where the others diverge. Any family- or model-specific page is reached from the brand hub below, and takes precedence over this one. Pages this one hands down to: Common DRIVEN Refrigerator Problems (driven-refrigerator-problems).
