The short answer
On this cabinet the freezer shelf is a plate you defrost by hand, and frost on that plate is the reason a tray takes all day. Ranked first on this platform: Frost on the freezer plate instead of ice in the tray. The checks below follow that ranking, and the first of them need no tools and no panel removed.
What you observe
- A thick layer of frost on the plate and a tray that takes all day — Frost on the plate and slush in the tray is one fault seen from two sides.
- 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
- Frost on the freezer plate instead of ice in the tray — On a manual-defrost compact, the plate is both the cooling surface and the frost collector. It ranks first on this platform because the plate has no heater and nobody defrosts it on schedule, so frost thickens until it insulates the plate from the compartment — and the tray an inch away freezes more slowly every week.
- A temperature control set too warm for freezing — One dial serves both compartments on a compact cabinet. It ranks second here because this cabinet has no defrost heater at all: the freezer shelf frosts until somebody switches the unit off and lets it melt.
- 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
- Look at the thickness of the frost on the plate before anything else — Anything more than a light fur is enough to explain the complaint. 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
- Empty the compartment and defrost it fully with the cabinet switched off — Let it melt rather than chipping it; a chipped plate is a punctured evaporator, and that ends the cabinet.
Tools: cloth, towelAbout 30 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 at the first panel that needs a tool, and write up what you found — A technician who arrives knowing which checks came back clean spends the visit fixing rather than repeating them.
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 MicroFridge by Danby with Safe Plug 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.
