The short answer
A thermoelectric beverage cabinet cannot make ice, and no setting, part or repair will change that. Ranked first on this platform: This cabinet cannot make ice at all. The checks below follow that ranking, and the first of them need no tools and no panel removed.
What you observe
- It chills but nothing in it ever freezes, whatever the setting — A cabinet that has never frozen anything is not one that has stopped freezing.
- Ice forms in winter and stops in summer, or in one room and not another — A result that follows the room is a result about the room.
- Frost builds on a small plate at the top while nothing else in the cabinet freezes — That is the plate doing its job in a cabinet with no freezer.
- NEAR MISS — ice forms and then welds itself into one lump — Clumping is a melt-and-refreeze symptom: the compartment is warming between cycles, which is a door or a temperature question.
Causes, most likely first on this platform
- This cabinet cannot make ice at all — A thermoelectric cabinet holds a fixed difference below the room rather than reaching a set temperature, and that difference does not reach freezing in any normal room. It ranks first on this platform because there is no freezer compartment anywhere in this cabinet and no ice maker was ever fitted to it: what it has is a chilled space for bottles, and asking it for ice is asking for a capability the design does not contain.
- A room too warm for the cabinet to reach freezing — A small cabinet can only pull its interior a limited distance below the room. It ranks second here because a thermoelectric cooler does not refrigerate to a set temperature: it holds the cabinet a fixed number of degrees below whatever the room is, so in a warm room it will never reach fridge temperature no matter how long it runs.
- The cold plate frosts but the cabinet has no freezer — A minibar has a small cold plate rather than a freezer compartment. It will frost, and a tray pressed against it may eventually freeze, but the cabinet has no ice-making capability and no setting that adds one. It ranks third rather than higher: real on this platform, and less common than the causes above it.
Check in this order, and why
- Measure the room, measure the cabinet, and look at the difference — The difference is the specification, and the specification is the answer. It leads because it tests the top-ranked cause.
- Measure the room where the cabinet stands and compare it with the rating on the plate — The plate states the band the cabinet was designed for. Tests the second-ranked cause.
- Identify whether there is a freezer compartment or only a cold plate — It decides whether the expectation is reasonable before any part is considered. Tests the third-ranked cause.
What an owner can safely check
- Put a thermometer in the cabinet and one beside it, and read both after a few hours — Once you see the difference rather than the reading, the behaviour stops looking like a fault.

- Put a thermometer beside the cabinet for a day and note the high — If the room is above the rated band, moving the cabinet achieves what no part will.

- 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 Mountain Dew 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.
