The short answer
A freezer that is running but not holding temperature is usually losing the battle rather than losing a part. On a compact cabinet the ranking below puts heat load and airflow ahead of component failure, because that is the order in which these cabinets actually fail.
What you observe
- Contents soft or partly thawed with the unit still running — The box is losing more heat than it is removing.
- Heavy frost on the walls or the lid seal — Humid air is getting in continuously, which is both a symptom and a cause.
- NEAR MISS: nothing running and everything thawed — That is a power or control failure and belongs on a different page.
Causes, most likely first on this cabinet
- The room the cabinet stands in — A freezer in an unheated garage, a hot utility room or a closed cupboard is outside what it was rated for. Ranked first on Danby Premiere: a compact freezer carries very little margin in its seal, its clearance or its drain, so whatever the installation is straining shows up long before any component wears out, and a frost-free cabinet with a separate freezer compartment has an air path between the two that a single-door unit does not.
- Frost build-up on the walls or the evaporator — On a manual-defrost cabinet, frost is insulation: the thicker it gets the less heat the walls can pull out, and the cabinet steadily loses ground to itself. Ranked second: it ranks here because it is common enough to be worth checking, but only once the free checks above are clean.
- The lid or door seal — A gasket that has taken a set, a lid propped by a packet, or a hinge that has dropped. Ranked third: it is in the middle of the list because it is cheap to rule out and expensive to assume.
- A sealed-system or compressor fault — Refrigerant loss or a compressor that will not pump. Ranked last: it is last because on an appliance this size the major components outlive everything around them, and replacing one often costs more than the appliance is worth.
Check in this order, and why
- Check the clearance and the room temperature — Clearance on all sides and a room inside the rated range.
- Look at the thickness of the frost layer — A layer you can push a finger into rather than a dusting means the cabinet needs defrosting before anything else is judged.
- Paper-test the seal all the way round — Anywhere the paper slides free is a leak.
What an owner can safely check
- Open up the space around the cabinet and check the room against the rating plate — Pull it clear of the wall, take whatever is stacked on top off and confirm the room is inside the range the plate specifies.
Tools: tape measureAbout 15 min
- Empty the cabinet and run a full manual defrost — Move the contents to a cooler, leave the lid open until the walls are clear and bare, dry it and restart.
Tools: towels, coolerAbout 90 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 cabinet or switch off its breaker before removing any panel, and keep it off while you work: a capacitor can hold a charge after the power is off. Never chip frost off with a knife, a chisel or a screwdriver, because the evaporator tubing runs immediately behind the wall you are chipping and a puncture ends the cabinet. Warm water, a plastic scraper and time are the only correct tools.
When to call a technician
Call once the seal, the environment, the frost and the coil have all been dealt with and the cabinet still cannot hold temperature, because what is left needs instruments. Call immediately if you see oil at the tubing, smell burning, or find the cabinet hot at the compressor with no cold anywhere.

What this page does not cover
This page covers the Danby Premiere freezer as a class, not one model or production run. Any family- or model-specific page for your unit takes precedence over it. Not here: the thermostat range, the coil layout and the defrost arrangement for your specific cabinet, all of which vary by model.
