The short answer
A cabinet that runs continuously and still warms up is almost never a dead compressor — a dead compressor is silent. It is nearly always something between the cold and the food: airflow, heat rejection, or a control that has stopped asking for cooling at the right moment. On a R-Vision refrigerator the cause that ranks first is supply voltage sagging under load.
What you observe
- The cabinet is warm but you can hear it running — The compressor hum is there and steady; the air inside is not cold.
- Frost has built into a sheet on the freezer back wall — A light dusting is normal.
- NEAR MISS — the cabinet is silent and nothing is cold — That is a supply, start-relay or thermostat-open fault, and it belongs on the no-power page rather than this one.
Causes, most likely first on a R-Vision refrigerator
- Supply voltage sagging under load — A compressor that cannot start on a weak supply will hum, draw current and cut out on its overload, over and over, without producing cold. Ranked first on this refrigerator, because a marginal supply produces exactly this symptom and is invisible unless you look for it.
- Airflow closed off by a frosted evaporator — The defrost cycle stalls before it fails outright, so ice builds behind the rear freezer panel over weeks and closes the air path.
- Evaporator fan motor stopped — The fan behind the freezer rear panel is what pushes cold into both compartments.
- Ambient load beyond what the cabinet can carry — A compact system has very little reserve.
Check in this order, and why
- Check how the cabinet is fed and what else is on the same supply — A compressor that clicks and stops repeatedly is telling you about its supply, not its sealed system.
- Look behind the freezer rear panel for a frost sheet — It confirms or clears the airflow cause before any part is considered, and it needs nothing but a screwdriver and a light.
- Stand at the open freezer and listen for the fan — It separates the two likeliest causes in seconds, before any tool comes out.
What an owner can safely check
- Move the cabinet to a supply of its own and watch whether the compressor starts cleanly — A compressor that hums, clicks off and retries is a supply symptom.
About 15 min
- Empty the cabinet, switch it off at the wall and leave both doors open until every trace of frost is gone — A full manual defrost takes hours, not minutes.
About 45 min
- Open the freezer and listen for the fan with the door switch held in — On most cabinets the fan stops when the door opens; hold the switch in to hear whether it runs.
Tools: torchAbout 10 min
- STOP HERE if the next step needs a meter on live terminals or a panel off — That is where an owner check ends and a service call begins, whatever the ranking above says.
Before you open anything
Safety
Unplug the cabinet or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Do not defeat the freezer door switch by wedging it; hold it in by hand for the moment you need to listen, then let it go. Refrigerant work is licensed work: never open, cut or braze a sealed-system line, and do not attempt to add refrigerant to a domestic cabinet.
When to call a technician
Call once the airflow, heat-rejection and seal checks are all clean, because what is left is behind a meter or inside the sealed system. Call immediately if you see oil at the compressor or at any tube joint: oil outside the tubing means the loop is open, and every further hour of running makes the repair larger.

What this page does not cover
This page is written for the R-Vision refrigerator as a class, not for one family or model line. Where a family- or model-specific page exists for your unit it is linked above, it is the more specific answer, and it is the one to read first. Deliberately not here: part numbers, wiring colours, panel removal order and torque figures, which differ between families under the same nameplate.
