The short answer
On a True refrigerator, this symptom is almost never a dead compressor. It is airflow: something is stopping cold air from moving, or stopping heat from leaving. Because the badge covers two very different product families, the first job on this page is to work out which kind of cabinet you have, and the ranking says how.
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.
- 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
- Warm room air walking in past a gasket that no longer touches all the way round — Ranked first on True: in a working kitchen the door is opened many times an hour by people carrying things, so the gasket, the hinge and the closer take the whole load. On this one, remember that the badge spans commercial and residential cabinets, so establish which one you have before anything else.
- Condenser coil or grille blocked, so heat cannot leave the cabinet — Second: a kitchen fills a condenser with grease-laden dust faster than a house does, and a commercial cabinet is usually standing in the hottest room in the building.
- A control that thinks the cabinet is already cold — Third: it is uncommon, it cannot be confirmed without instruments, and it looks identical from outside to the causes above it.
- Sealed-system or compressor fault — Ranked last here, deliberately: commercial decks are built heavy and are usually the last thing to fail, which is exactly why it sits last.
Check in this order, and why
- First — close the door on a sheet of paper at several points round the seal — If the paper slides out freely anywhere, that part of the seal is not working and the cabinet is fighting the room.
- Then — look at the condenser and its air path — grille, back panel or the space around the cabinet — It is free, it needs no tools, and it decides whether anything else on this list is worth checking.
- 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
- Test the gasket all the way round with a strip of paper — Shut the door on a strip of paper and pull. Repeat at top, bottom and both sides. Free movement anywhere means a leak there.
Tools: paperAbout 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.

What this page does not cover
This page is written for the True 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.
