The short answer
A slim compact has a shelf and a tray, not an ice maker, so this is a temperature question from the first line. Ranked first on this platform: The cabinet has no automatic ice maker at all. The checks below follow that ranking, and the first of them need no tools and no panel removed.
What you observe
- There is no ice bin, no bail arm and no water connection anywhere on the cabinet — A cabinet with no water line was never going to make ice on its own.
- The fridge section is perfectly cold and only the freezer shelf underperforms — A split like that on a single-control cabinet is the control, not a component.
- Ice production slowed at the same time as other frozen food got softer — Two symptoms with one date are one cause.
- NEAR MISS — the tray freezes but the ice tastes of the cabinet — That is an odour and storage question rather than a production one, and a covered tray solves it.
Causes, most likely first on this platform
- The cabinet has no automatic ice maker at all — A compact cabinet of this class is not built with an ice maker. It ranks first on this platform because the cabinet has no water connection anywhere on it, which rules out every plumbing cause in one observation and leaves only the question of whether the shelf gets cold enough for long enough.
- A temperature control set too warm for freezing — One dial serves both compartments on a compact cabinet. It ranks second here because the cabinet is unusually narrow for its height, so the compressor sits close to the side panel and any contact between the two is audible across the room.
- The freezer is not cold enough to harvest — An ice maker will not eject until the mould thermostat sees its harvest temperature. It comes third in the order — a genuine cause here, behind the ones above it on frequency alone.
Check in this order, and why
- Establish whether there is a water connection behind the cabinet at all — It redirects the whole diagnosis from a water fault to a temperature one. It leads because it tests the top-ranked cause.
- Turn the control colder by one step and give it a full day — One step at a time is the only way to find the setting that serves both compartments. Tests the second-ranked cause.
- Put a thermometer in the freezer and give it several hours — A freezer holds food safely at 0 °F (−18 °C) or below; if it is above that, the ice maker is a symptom rather than the fault. Tests the third-ranked cause.
What an owner can safely check
- Fill a tray with cold water, set it flat on the freezer shelf and leave it overnight — A tray that does not freeze solid overnight is a temperature problem; a tray that does means the cabinet is fine.
About 15 min
- Move the dial one step colder and leave a tray of water in overnight — Judge it by the tray rather than by the dial.
About 15 min
- STOP here — the remaining causes are diagnosed with a meter, not by eye — Record which of the checks above changed anything. That record is worth more to the visit than another attempt.
Before you work on the water side
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off.
When to call a technician
Call if the compartment will not reach a freezing temperature after the control, the frost and the room have all been dealt with, because what is left is the cooling system itself.

What this page does not cover
This page is written for the MooSoo refrigerator as a class, not for one family or one model line. Where a family- or model-specific page exists for your unit, that page is the more specific answer and the one to read first. Deliberately not here: part numbers, wiring colours and disassembly order, which differ by family.
