The short answer
On the CF series of Atlas Homegoods refrigerators, a cabinet that runs and will not get cold leads first to a temperature sensor or control reading the box wrongly. Where the brand-generic article leads on a stalled defrost cycle icing the evaporator over, this roster reverses the top two — the first check is the one you can reach on these cabinets without a teardown. 3 of the 4 causes below can be checked without a tool; the rest need a technician.
What you actually see
- The cabinet is warm and the compressor is plainly running — You can hear it working from the back or the base, and the air inside is still nothing like cold.
- The compressor never cycles off — A unit that runs without ever reaching its cut-out is telling you it cannot get there, not that it is trying harder.
- Food at the front is cold while food at the back is frozen — Uneven, not warm, which is a distribution problem and usually a damper or a loaded vent.
- It has been quietly getting worse for months — Slow decline points at something that accumulates — dust, frost, a seal taking a set — rather than at a part that failed.
- NEAR MISS — the cabinet is silent, dark and completely dead — That is a power or control fault and it is a different page. Nothing below will help you.
Causes, most likely first on the CF series
- A temperature sensor or control reading the box wrongly — If the control believes the cabinet is already cold it will stop calling for cooling. A sensor drifting out of range produces exactly this: a warm box and a machine that thinks it is finished.
- A choked condenser coil, or no air around the cabinet — Dust on the coil is insulation on the one part whose job is to shed heat, and a cabinet pushed tight into a recess has nowhere to shed it to. It is first here because it is the cause that arrives slowly enough for nobody to notice the day it started.
- A door gasket that has stopped sealing — A gasket that has taken a set, or a door that no longer closes square on its hinges, leaks warm wet air in continuously. The tell is frost or sweat that always forms at the same corner.
- A start relay or overload that will not bring the compressor up — If the compressor is not actually running, nothing downstream matters. A relay that clicks and drops out leaves a cabinet that is silent between clicks and never gets cold.
The order to work in
- Check the clearance around the cabinet and the door seal all the way round — Both are free, both are common, and both are things a technician will check first anyway.
- Put a thermometer in a glass of water in the middle shelf overnight — Cabinet air temperature swings every time the door opens; water does not, so it tells you what the food is actually seeing.
- Only then consider the control and the sealed system — They are last because they are the two that cost money to be wrong about.
Before you open anything
Safety
Nothing below happens on a live machine. Unplug it or switch off its breaker before any panel comes off, and remember a capacitor can hold a charge after the power is off. Never chip ice off a compartment wall with anything metal. The evaporator is close behind that surface and a pierced one ends the cabinet. If at any point a check would mean holding a part shut, propping a switch or running the machine open, stop: that is the point where this page ends.

When to call a technician
Draw the line this way: what you can see, reach and clear with the machine isolated is owner work; anything on the sealed system, and anything needing a reading rather than an observation is not. On this page that puts a start relay or overload that will not bring the compressor up on the far side of the line.
