The short answer
A Driven refrigerator that hums away without getting cold is usually failing to move its cold air rather than failing to make it, and that is good news: most of the causes are owner-checkable. The ranking below is ordered for this class of unit, and only the last cause on it needs a technician.
What you are seeing and hearing
- Frost has built up as a sheet on the freezer back wall — A solid sheet rather than the usual light dusting.
- The machine has behaved this way since it was fairly new — A platform built to a price tends to show its weak points early rather than after years.
- NEAR MISS: the unit is silent and the interior light is out — That is a supply or start-relay fault and it belongs on the page for a unit that will not start.
What it usually turns out to be, ranked
- A frosted evaporator choking the airflow — The defrost cycle stalls, ice sheets across the evaporator behind the freezer wall, and the fan can no longer push cold air forward. Ranked first on a Driven refrigerator: a restriction mimics a failed component exactly, and it is far commoner than one.
- A condenser coil blanketed in dust or standing in its own heat — The coil can only shed heat into air that moves. Ranked second on a Driven refrigerator: the surrounding air decides how hard the machine has to work, so the environment is settled first.
- A door seal that no longer pulls the door shut — A gasket that has taken a set, or a door that no longer sits square, lets a thin stream of room air in continuously. Ranked third on a Driven refrigerator: seals on this class of machine are thin and take a set early, which moves them up the list.
- A packed cabinet, a warm load or a door being opened to check — Air has to circulate to carry heat to the evaporator. Ranked fourth on a Driven refrigerator: a machine built to a price is usually asked to do more than it was designed for, so habits come before hardware.
The order to work in, and the reason for it
- Look at the freezer back wall for a solid sheet of frost — Frost as a sheet rather than a light dusting settles this in seconds.
- Feel the condenser at the back or underneath and look at how clear it is — A coil that is hot and dusty is the cheapest cause on this list.
- Close the door on a sheet of paper and pull it out at several points around the frame — Anywhere the paper slides out freely is a gap.
Owner checks, in order
- Empty the unit, switch it off and leave both doors open until every trace of ice has gone — Cold that comes back afterwards and then fades again over days is the defrost system rather than the compressor.
Tools: towels, coolerAbout 90 min
- Pull the unit out, vacuum the condenser coil and clear the space around it — Leave the clearance the manufacturer asks for at the back and the sides.
Tools: vacuum, soft brushAbout 25 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 unit or switch off its breaker before removing any panel: a capacitor can hold a charge after the power is off. Refrigerant work is licensed work, so never cut, bend or solder the tubing, and never run the unit with the sealed system open. A loaded refrigerator is heavy and top-sided, so get help to move it rather than walking it on a corner.
When to call a technician
Call once the coil, the seal and the airflow are all clean and the cabinet still will not hold, because what is left is a fan, a sensor or the sealed system and two of those need a meter. Call immediately if you see oil around the compressor or smell burning: oil outside the tubing means the system is open, and every hour it runs after that costs more to put right.

What this page does not cover
This page is written for the Driven refrigerator as a class, not for one family or model line. Shelf layouts, defrost-control types, fan placement and part numbers all change from build to build and are deliberately not here. Where a family- or model-specific page exists for your unit, it is the more specific answer and the one to read first.
