Start here
When a TW unit stops cooling, the useful split is whether it makes no cold at all or makes cold it cannot distribute. Separate a stopped fan from a sealed-system fault early, because one is a modest repair and the other decides the unit, and that distinction decides everything that follows. Start with a fan that has stopped and leave a loss of refrigerant charge until everything cheaper has been excluded.
The observables
- 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.
- The panel is lit and nothing ever starts — The electronics are alive but no cooling is ever called for.
- It was fine until the weather turned — The same unit in the same place, coping in spring and failing in a hot room.
- A sheet of ice on the cold plate — Frost thick enough to feel as a layer, with the cabinet warm despite it.
- 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 fan that has stopped — It ranks above the expensive causes for that reason alone: it is the cheap fault that impersonates the expensive one.
- The condenser unable to shed heat — Second: this is the fault that arrives with the summer: the same clearance that coped in spring is not enough when the room is warm, and the unit crosses from just coping to not coping.
- A frosted plate blocking airflow — Third, and worth excluding before going further: once the cold plate carries a sheet of frost, the cabinet is insulated from its own cooling. The compressor runs, the plate gets colder, and the air in the cabinet does not, so the unit fails while doing everything right.
- A loss of refrigerant charge — It ranks last deliberately: every cause above it produces the same warm cabinet for a fraction of the cost.
The order to work in
- Establish whether air is moving at all — Listen at the machinery end and at the compartment for airflow while the compressor runs. Silence where there should be air is the finding.
- 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.
- Look at the plate before concluding anything — Look for a sheet rather than a dusting. If it is a sheet, defrost the unit fully with the door open and run it again; recovery confirms airflow was the problem.
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
Everything reachable without a panel is owner work. Repeated failed starts, a fan motor, a sensor disagreement or anything on the sealed system is not, because those need measurement and refrigerant work is licensed work.
