The short answer
There is no ice maker in a cabinet of this kind, so this is a temperature question: the chiller box shares one cooling plate with the whole fridge, and anything that loads the cabinet slows the tray. Frost on the plate and a warm setting explain almost all of these.
What you actually see and hear
- Trays take far longer than they used to — Gradual loss, which almost always means frost has built up on the plate.
- Cubes freeze at the back of the tray and stay liquid at the front — Uneven contact with the cold plate, or a tray that is not sitting flat.
- Nothing freezes at all and the fridge itself is only cool — This is a cooling problem for the whole cabinet, not an ice problem.
- NEAR MISS - ice forms on the box and on the food rather than in the tray — That is frost accumulation, which is normal here and needs a manual defrost.
Causes, most likely first on this machine
- Frost on the cooling plate insulating the chiller box — First. Every manual-defrost cabinet accumulates frost, and the box is the first thing to lose performance when it does.
- Thermostat set too warm for freezing — Second. One dial serves the whole cabinet, so a setting that keeps milk cold may not take a tray to solid ice.
- Door openings and a warm room — Third. A small cabinet is emptied of cold air every time the door opens, and the chiller box pays for it first.
- The tray itself - material, fill level and seating — Fourth, and easy to dismiss, but a deep plastic tray not touching the cold surface freezes far more slowly than a shallow one that does.
- A cabinet that is not reaching temperature at all — Last, and if it applies, it supersedes everything above: fix the cooling first and the ice follows.
Check in this order, and why
- Put a thermometer in the chiller box overnight — It turns a vague complaint into a number you can act on.
- Look at the cooling plate for frost — Thick frost is a complete explanation and the fix is a defrost.
- Turn the thermostat colder by one step and wait a full day — Compact cabinets respond slowly; give the change time to show.
- Try a shallow metal tray sitting flat on the cold surface — Removes the tray from the list of suspects in one go.
What an owner can safely check
- Defrost the cabinet completely with the power off and the door open — Let all the frost melt, dry the plate, and restart.
Tools: towels, shallow trayAbout 240 min
- Move the thermostat one step colder and leave it a full day — Judge by the thermometer, not by feel.
Tools: thermometerAbout 10 min
- Reposition the tray so it sits flat against the cold surface — Direct contact is most of the freezing rate on a static cabinet.
About 5 min
- Keep the cabinet away from heat and out of direct sun — A hot room loads the whole cabinet and the chiller box loses first.
About 10 min
- STOP HERE if the cabinet itself will not get cold — Then the ice is a symptom and the cooling page is the right one.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel - a capacitor can hold a charge after the power is off. The compressor and its start relay sit at the back behind a small cover and stay hot and live until the unit is unplugged. Never chip frost off the cooling plate with a knife or a screwdriver: the plate has refrigerant tubing bonded to it, and a puncture ends the appliance.
When to call a technician
Call only when the whole cabinet cannot get cold, because a chiller box that will not freeze in a cabinet that is otherwise cold is a setting, a frost layer or a tray - none of which needs a technician. If the cabinet will not cool either, that is the fault to describe when you call. Be aware that a sealed-system repair on a compact unit is often close to the price of replacing it, so ask for the cause to be named before agreeing to a repair.

What this page does not cover
This page is written for the single-door compact refrigerator class, not for one family or model line. Where a brand- or model-specific page exists for your unit it is the more specific answer and it is linked above, so go there first if your machine is named. What is deliberately not here: compressor and relay part numbers, thermostat calibration figures, refrigerant charge and shelf dimensions, all of which differ by family and belong on the page for that family.
