The short answer
Read the star rating on the compartment before anything else: a low-rated ice box was never specified to freeze a tray from liquid. After that, a dial set too mild for the box is second, frost insulating the plate third, and a thermostat or sealed-system fault last. There is no icemaker on this class to fail.
What you observe
- A low star rating on the compartment flap — Short-term storage rather than a freezer.
- Frozen food keeps but a fresh tray will not set — Exactly what a low rating predicts.
- The fridge side is cold and the box is not — One control serving two very different jobs.
- A thick frost layer on the plate — Insulating it, and nothing removes it automatically.
- NEAR MISS — soft ice on a hot day — Expected in a small ice box.
Causes, most likely first on this brand
- A compartment rated for storage, not for freezing — First because the expectation is the fault. A low-rated ice box holds already-frozen food briefly and was never specified to take a tray of water down to solid, however long you leave it.
- Dial set too mild for the ice box — Second: one control serves the whole cabinet, so a setting that keeps the fridge comfortable can leave the box barely below freezing even on a machine rated to do better.
- Frost insulating the plate — Third, and cumulative: with no automatic defrost, frost thickens until the plate can no longer take heat out of a tray resting against it.
- Thermostat or sealed-system fault — Last. Its tell is a cabinet that is also failing on the fridge side, and at this price point that is usually a replacement conversation.
Check in this order, and why
- Read the star rating on the compartment — Free, and it often ends the investigation.
- Turn the dial colder and wait a full day — The only setting change with a real chance of helping.
- Look at how much frost is on the plate — A thick layer explains a slow decline.
- Check whether the fridge side is cold too — Left until here because it points at the whole cabinet.
What an owner can safely check
- Find the star rating on the flap and the rating plate — Photograph both. Any enquiry will need them.
About 15 min
- Leave a thermometer in the compartment overnight — Read it before changing anything else.
Tools: thermometerAbout 20 min
- Turn the dial colder and leave it a full day — Judge by the thermometer rather than by feel.
About 20 min
- Empty the box and let the plate defrost fully — Dry it before restarting. Never chip at frost.
Tools: towelAbout 60 min
- STOP HERE if the fridge side is also failing — Thermostat and sealed-system work is a service call.
Before you open anything
Safety
Unplug the refrigerator before removing a panel or reaching behind it; a capacitor can hold a charge after the power is off. Never chip frost off the plate with a knife or screwdriver — the plate is thin and a puncture releases refrigerant under pressure and ends the cabinet. A freezer proper should hold zero degrees Fahrenheit, which is eighteen degrees Celsius below zero.
When to call a technician
Call when the compartment is rated to freeze, the dial is at its coldest, the plate is clear and a tray still will not set — the thermostat or the sealed system is then the answer. Give them the rating plate details rather than the brand name. Ask for the cost against a replacement before authorising anything at this price point.

What this page does not cover
This page is written for the brand and the appliance class, not for one family or model line. Where a family- or model-specific page exists for your unit, that page is the more specific answer and you should start there. Deliberately absent: star rating thresholds, dial calibrations, thermostat part identifiers and fault-code meanings, all of which differ between the static single-door, frost-free top-freezer and under-counter families.
