The short answer
Ice that will not form in a BestHome under-counter cabinet is usually the freezer box iced over, a box flap that will not close, or a cabinet that is marginal on ventilation and never gets cold enough to freeze. There is no plumbed icemaker on most cabinets of this class, so there is no fill valve to blame.
What you observe
- Trays take a day or more to freeze — The box is near freezing rather than below it.
- Cubes are soft, cloudy or fused together — Slow freezing, or repeated partial thawing.
- The freezer box is coated in a thick ice layer — The surface that should be freezing your tray is insulated.
- NEAR MISS — nothing in the cabinet is properly cold — Then this is a cooling failure and the ice is its earliest symptom.
Causes, most likely first on this brand
- Ice across the freezer box or cold plate — First on a manual-defrost cabinet: ice on the cooling surface is insulation, and it builds quietly until ice-making is the first thing to fail.
- A box flap held open — Second: the flap is light plastic, and an over-tall tray or a bag of frozen food holds it open. The box then runs at fridge temperature.
- A cabinet marginal on ventilation — Third, and specific to a built-under installation. A cabinet that cannot quite reject its heat will keep food acceptably cool and still never get the box cold enough for good ice.
- Tray fill and placement — Fourth: on a static surface the cold comes from contact, so a brimming tray on a wire shelf freezes far more slowly than a shallow one set flat against the plate.
Check in this order, and why
- Look at the box and the cooling surface for ice — The likeliest cause and visible immediately.
- Shut the flap and see whether it stays shut — A flap held open explains the whole complaint.
- Pull the front grille and check the airflow — On this format, poor ventilation shows up in the ice first.
- Move a shallow tray into direct contact with the cold surface — If that one freezes normally, placement was the fault.
What an owner can safely check
- Defrost the box and the cooling surface completely — Unplug the cabinet, empty it, and let the ice melt. Never chip at it.
Tools: towelsAbout 60 min
- Clear the box so the flap closes on its own weight — Trays should sit flat with nothing holding the flap.
About 10 min
- Remove and vacuum the front grille — Ice-making recovers with ventilation more often than owners expect.
Tools: vacuum, soft brushAbout 20 min
- Fill trays shallower and set them flat — A shallow tray freezes far sooner on a static cold surface.
About 5 min
- Set the dial a step colder and wait a day — Watch the salad drawer for freezing as you go.

Safety
Unplug the cabinet or switch it off at its breaker before defrosting the box or removing the grille — a capacitor can hold a charge after the power is off. Never chip or lever ice off the freezer box or the cold plate: the tubing is bonded behind them and a puncture ends the appliance. Do not use hot water or a hair dryer inside the cabinet.
When to call a technician
Call when the box has been defrosted, the flap closes, the grille is clear, the dial is at a cold setting, and trays still will not freeze overnight. That means the box is not reaching freezing temperature at all, which points at the thermostat or the sealed system. Call sooner if food in the fresh-food section is also warm.

What this page does not cover
This page covers BestHome under-counter refrigerators as a class rather than one model line, and most cabinets of this class have no plumbed icemaker. Deliberately absent here: box capacities, thermostat ranges, freezing times and part identifiers, which differ by family and belong on the family or model page.
