Start here
When a T unit stops cooling, the useful split is whether it makes no cold at all or makes cold it cannot distribute. A cabinet stable at the wrong temperature is being controlled correctly to the wrong number, and that distinction decides everything that follows.
The observables
- It runs for a few minutes, stops, and starts again — The same short cycle repeated all day, with the cabinet never coming down.
- Cold at the plate, warm at the far end of the cabinet — Cooling is being made but not distributed, which points at air rather than at the system.
- A hum or a click every few minutes and no sustained run — Something attempts to start and drops out, and the machinery end never warms.
- NEAR MISS - completely silent with no lights — That is a supply or power fault before it is a cooling fault: check what is reaching the unit first.
Causes, most likely first on this line
- A setting or mode that is not what the owner thinks — First here, and by a wide margin: this is worth ranking rather than mentioning, because it is the one cause that produces a perfectly working unit and a dissatisfied owner, and because a service call cannot fix it.
- The condenser unable to shed heat — Second on this line: a condenser boxed in, dusty or pressed against a wall cannot give up heat, so the compressor runs and runs and the cabinet never reaches temperature. The unit looks healthy and performs like a broken one.
- A door or lid that is not sealing — It ranks where it does because it explains a warm cabinet and continuous running together, which is the exact combination most often reported.
- A control or sensor reading the cabinet wrongly — Last on the list, and the only one here that is not owner work: this is distinguishable from a supply fault because the electronics are clearly alive, and from a compressor fault because nothing ever tries to start.
The order to work in
- Read the setting back and the temperature with it — Read the setpoint and the mode as they actually are, then measure the cabinet with a thermometer rather than by hand. A refrigerator holds food safely at 40 degrees Fahrenheit, which is 4 degrees Celsius, or below.
- Give the condenser air and a clean grille — Feel the machinery end while it runs: it should be warm. A unit running continuously with a cool condenser has a different problem from one running continuously with a hot one.
- Test the seal at several points — Close the door on a strip of paper at the top, the middle and the bottom of each side and pull. Anywhere it slides out freely is a leak, and the coldest part of the cabinet will be furthest from it.
Before any panel comes off
Safety
Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. Never open pipework or attempt anything on the sealed system - refrigerant work is licensed work and the tools for it are not owner tools.

When this stops being owner work
Two conditions end the owner checks here: a cabinet that will not come down with the condenser clear, the door sealing and the setpoint proven, and any sign of oil or damage at the machinery end. The second is urgent rather than routine.
