What this usually is on these models
A TWW unit that runs constantly and stays warm is working hard at something that is not cooling. A unit that never tries to start is being told not to, which is a different fault from one that tries and fails, so the checks below start outside the cabinet and move in.
What you observe
- Cabinet temperature is stable but higher than expected — Steady rather than drifting, which usually means the control is holding it there on purpose.
- The compressor runs constantly and the cabinet stays warm — Never reaches temperature, never stops trying, and the machinery end is hot to the touch.
- It runs for a few minutes, stops, and starts again — The same short cycle repeated all day, with the cabinet never coming down.
- NEAR MISS - cold but leaking water — A cabinet that holds temperature and leaves puddles is a drainage fault, and the water leak page for this line covers it.
Ranked causes for these models
- A control or sensor reading the cabinet wrongly — Ranked first on this line: if the control believes the cabinet is already cold, it will not call for cooling, and the unit sits quietly doing nothing while the contents warm. A silent unit with a lit panel is the picture.
- A setting or mode that is not what the owner thinks — Next, and close behind: the tell is a cabinet that is stable at the wrong temperature rather than one that is drifting: stability means the control is doing exactly what it was told.
- A marginal supply or lead — Then: leads, adaptors and a socket shared with something heavy are the usual weak points. The unit is fine; what reaches it is not, and that shows up as repeated short runs rather than as a dead machine.
- A start component that has failed — Last, and the reason the order matters: a compressor that cannot start hums for a moment and then drops out on its protector, over and over. The cause is usually the start device rather than the compressor itself, but confirming that is not owner work.
What to check first, second, third
- Compare what the unit says with what a thermometer says — Note whether the compressor ever attempts to start. A unit that never tries is being told not to.
- 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.
- Prove the supply before anything else — Note whether the unit clicks and stops, or runs continuously. Clicking and stopping points at supply or start; running continuously points at airflow.

Safety
Isolate the unit at the plug or the breaker before any panel comes off, because a capacitor can hold a charge after the power is off. If you find oil or a greasy film at the machinery end, stop: that means the sealed system is open and the unit should not be run.

When to call a technician
Call when the unit clicks or hums every few minutes without a sustained run and a different socket has already been ruled out, and call at once for a burning smell or a trip. Both patterns point past the owner checks.
