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
- The outside of the cabinet is warm to the touch along the sides — Normal on many cabinets, because the heat-rejection loop runs in the skin.
- Contents soft or partly thawed with the unit still running — The box is losing more heat than it is removing.
- 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 lid or door seal — A gasket that has taken a set, a lid propped by a packet, or a hinge that has dropped. Ranked first on Danby: 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 this line spans bar cabinets to apartment units, all of them designed to go where a full-size appliance would not.
- 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 second: it sits here because it produces the same complaint as the cause above it and takes longer to confirm.
- A condenser coil or skin that cannot shed heat — Dust on an exposed coil, or a cabinet pushed tight against a wall so the skin loop cannot lose heat. Ranked third: it ranks here because it is common enough to be worth checking, but only once the free checks above are clean.
- 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
- Paper-test the seal all the way round — Anywhere the paper slides free is a leak.
- Check the clearance and the room temperature — Clearance on all sides and a room inside the rated range.
- Feel the back or the sides of the cabinet — Very hot rather than warm, with dust visible on an exposed coil, points here.
What an owner can safely check
- Test the seal with paper and clear whatever is holding it open — Clean the gasket and the frame, move any packet fouling the seal and check the lid closes under its own weight.
Tools: sheet of paperAbout 15 min
- 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
- 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.
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 Danby as a family, not one model line. Where a page exists for the line named on your plate it is linked below and it is the more precise answer. Not here: the thermostat range, the coil layout and the defrost arrangement for your specific cabinet, all of which vary by model.
