The short answer
On a Transtherm refrigerator, this symptom is almost never a dead compressor. It is airflow: something is stopping cold air from moving, or stopping heat from leaving. A wine cabinet is tuned for stability, not for pull-down, so it fails softly: the band drifts long before anything sounds wrong.
What you are actually seeing
- The outside of the cabinet is hot to the touch at the sides or back — Heat is being made and not shed.
- Condensation or sweating on the door frame — Warm damp air is reaching a cold surface it should not reach.
- The compressor runs and runs without ever stopping — It never reaches its setting, so it never switches off.
- NEAR MISS — the unit is completely silent and nothing is cold — That is a power, start relay or control fault, and it is a different page. Check the outlet and the breaker first.
Causes, most likely first on this refrigerator
- The cabinet is in the wrong place or packed too tightly to circulate — Ranked first on Transtherm: a wine cabinet is tuned to hold a band, not to pull a warm room down, so a hot room reads as a failure when it is not one. On this one, remember that the cabinet is tuned to hold a narrow band, so it drifts long before it fails.
- A stalled or obstructed evaporator fan behind the freezer panel — Second: it produces exactly the same warm cabinet as a blocked coil, but with a different sound, which is why the listening check comes first.
- Condenser coil or grille blocked, so heat cannot leave the cabinet — Third: it is the one cause that the owner can both confirm and fix in a quarter of an hour, and on this platform it is the commonest single reason a cabinet runs without cooling.
- A fault on the sealed refrigerant system — Ranked last here, deliberately: it is the least common of the causes and the only one that is not an owner fix, so checking it first wastes the cheap checks above.
Check in this order, and why
- First — look at where the unit stands and how full it is — Check clearance behind and above, and check nothing inside is covering the vents at the back of the compartment.
- Then — open the freezer side and listen for the fan, then hold the door switch in — The fan should run with the door held closed; silence there separates this cause from the two above.
- Only then — feel whether the condenser is warm and listen for the compressor — Only worth doing once everything above is clean, because it changes nothing an owner can act on, which is why it comes after everything above it.
What an owner can safely check
- Clear the internal vents and give the cabinet its clearance — Move packaging off the vents at the back and top of the compartment, and pull the unit far enough from the wall that air can rise behind it.
About 10 min
- Clear the condenser coil and the air path around it — Pull the front grille or the lower back panel and vacuum the fins clean, then check nothing is stacked against the cabinet or over the vent.
Tools: vacuum, soft brushAbout 15 min
- STOP here if the next thing to check is behind a fixed panel — Everything above can be done without tools on live parts. Past this point it is a technician job.
Before you open anything
Safety
Unplug the cabinet or switch off its breaker before you take any panel off — a capacitor can hold a charge after the power is off. Do not tape, wedge or otherwise defeat a door switch to keep a fan running while you look: the switch is there so that a hand in the cabinet cannot meet a spinning blade. Refrigerant work is licensed work; nothing on the sealed system is an owner job.
When it stops being an owner job
Call once the air path, the gasket and the fan check are all clean, or straight away if the cabinet is silent, if the compressor buzzes and stops repeatedly, or if you can see oil around the tubing at the back. Oil outside the tubing means the sealed system is open, and every hour it runs after that costs more to put right.

This page is written for the Transtherm refrigerator as a class, not for one family or one model line. Where a family-specific page exists for your unit it is linked above and it is the more specific answer. Deliberately not here: part numbers, wiring colours, torque figures and any measured value, all of which differ by family.
