The short answer
A Costway cabinet that has stopped producing ice is more often obeying something than failing at it, whether that is a raised arm, a warm setting or a specification that never included freezing. On this class the usual cause is a single thermostat dial set too warm to freeze, with a door or flap seal letting warm air into the section next to rule out.
What you actually observe
- Ice comes back for a few days after the dial is moved — A control that responds and drifts names itself.
- Cubes come out small, hollow or misshapen — Shape is a flow story, and flow problems are fixed further upstream than the ice maker.
- NEAR MISS: water appears under the cabinet as well as no ice — A supply or drain leak changes the order of work, and the leak page covers it.
The causes, most likely first on this brand
- A single thermostat dial set too warm to freeze — On a cabinet with one dial for both compartments, a setting chosen for the fresh-food side leaves the freezer section short of freezing. Ranked first on a Costway unit: the entire control is one mechanical dial and it is both the cheapest part and the one that drifts.
- A door or flap seal letting warm air into the section — A freezer section behind a poor seal never settles at a freezing temperature, and a tray of water is the most sensitive indicator of that there is. Ranked second here: a light door on a cabinet that gets moved arrives out of square and the seal follows.
- A compartment loaded faster than it can freeze — Ranked third here: a small section filled in one go takes far longer than an evening.
- A room too warm for the cabinet to reach freezing — Ranked fourth here: last, though a portable cabinet ends up in warm rooms more often than a fitted one.
Check in this order, and why this order
- Note the dial position and put a thermometer in the freezer section overnight — One control serving two compartments always means a compromise, and this is where it shows.
- Shut a sheet of paper in the door or flap and pull it out — A sheet that slides free marks a dead length of seal, and the corners fail before the faces do.
- Count what went into the compartment in the last day — A section that froze fine last week and not this week has usually been asked for more.
What an owner can safely check
- Move the dial one step colder and give it a full day — Ice that appears on the colder setting means the cabinet is working and the setting was wrong.
Tools: thermometerAbout 10 min
- Wash the seal and its landing face with warm soapy water and dry both — Grease and sugar hold a seal open far more often than a torn seal does.
Tools: cloth, mild detergentAbout 15 min
- STOP HERE if the next step needs a meter on live terminals or a panel off — That is where an owner check ends and a service call begins.
Before you open anything
Safety
Unplug the unit or switch off its breaker before any panel comes off, and close the water shut-off before disturbing any fitting on the supply line. Never thaw a fill tube with a heat gun or an open flame, because the liner and the tubing behind it will not survive it. Never chip ice from a plate or a mould with a tool.
When to call a technician
Call once the supply, the temperature and the simple mechanical checks are all clean, because a fill valve or an ice maker module needs a meter and a panel off. Call sooner if you find water where it should not be, since a supply fault that leaks costs more the longer it runs. Bear in mind when you decide that parts for a value import are not stocked locally and a replacement unit can cost less than a part plus a labour call.

This page covers the Costway refrigerator as a class, not one family or model line. Ice maker module types, fill volumes and filter part numbers all change from build to build and are deliberately not here. Where a family or model page exists for your unit, it is the more specific answer and the one to read first.
