The short answer
The useful thing to know about a Vezeni refrigerator with this symptom is which cause to try first. Here that is The room is outside the cabinet's rated band, and the one to try last is A sealed-system or compressor fault. Everything near the top of the list is an owner check that costs nothing; the bottom of it is a service call.
What you actually observe
- The cabinet is warm but the unit is clearly running — You can hear the compressor; the air inside is not cold.
- It never switches off — It runs without ever satisfying its thermostat, which is the same fault seen from the other side.
- One part of the cabinet is cold and another is not — That is an airflow pattern rather than a cooling failure.
- NEAR MISS: the unit is silent and nothing is cold at all — That is a no-power or start-relay fault and it belongs on a different page.
Causes, most likely first on this build
- The room is outside the cabinet's rated band — Every cabinet is rated for a band of room temperatures, and outside that band it cannot reach its set point whatever is right or wrong inside it. Ranked first on a Vezeni: a countertop unit sits in the warmest air in the kitchen, right beside the things that make the kitchen warm.
- Frost built up on the cooling plate — On a manual-defrost cabinet the cooling plate frosts over in ordinary use, and once the frost is thick it insulates the plate from the air it is meant to be chilling. Second here, because a hand-filled, hand-emptied unit depends on the owner's routine more than on any part inside it.
- A thermostat or sensor reading the wrong temperature — The control only knows what its sensor tells it. Third, once the two above are clean: it is free, immediate, and it decides whether this is a fault at all.
- A sealed-system or compressor fault — A refrigerant leak or a failed compressor leaves nothing to carry the heat away. Last, and the reason the order above matters: it is the rarest cause and the only one that is not an owner fix on a unit this small.
Check in this order, and why
- Find out how warm the room actually gets, not how warm it feels — A room that swings outside the rated band explains the whole complaint without anything being broken.
- Look at the cooling plate or the freezer compartment for frost — A thick sheet rather than a light dusting names the cause before any tool comes out.
- Compare what the cabinet reports with a separate thermometer left inside it — A disagreement points at the sensing rather than at the cooling.
What an owner can safely check
- Move the cabinet away from the oven, the dishwasher and any sunlit worktop — A countertop cabinet stands in the warmest air in the kitchen, beside the things that make the kitchen warm.
About 15 min
- Empty the cabinet, switch it off and leave the door open until every trace of frost is gone — No tools.
About 45 min
- STOP HERE if the next step needs a meter on live terminals or any work on the sealed system — That is where an owner check ends and a service call begins.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel, because a capacitor can hold a charge after the power is off. Leave the door switch wired exactly as it is: it cuts power to the fan for a reason, and defeating it is never part of a diagnosis.
When to call a technician
Call once the clearance, the coil, the gasket and the load inside are all clean and the cabinet still will not hold its band, or the moment the fault is on the sealed system: refrigerant work is licensed and the tools for it are not owner tools. Call immediately if you smell burning, or see oil around the compressor, because oil outside the tubing means the system is open and every hour it runs after that costs more to put right.
