Atlas Homegoods CFC Series Refrigerator is the scope of this page, and on it a cabinet that runs and will not get cold points first at a choked condenser coil, or no air around the cabinet. That differs from the brand-generic page above, which leads on a stalled defrost cycle icing the evaporator over: on this roster the access and the layout move it down a place. 2 of the 4 causes below can be checked without a tool; the rest need a technician.
What you observe
- One compartment holds and the other does not — Cold air is being made but it is not reaching everywhere, which points at airflow rather than at the sealed system.
- A sheet of frost has built on the back wall inside — Not the usual light dusting, but a slab that closes off the vent openings behind it.
- The cabinet cools better when it is nearly empty — A machine that can just manage a light load and not a full one is short of capacity rather than broken.
- NEAR MISS — the cabinet is cold but the ice maker is empty — Cooling is fine; the problem is in the ice circuit, which is covered on its own page.
Causes, most likely first on the CFC series
- A choked condenser coil, or no air around the cabinet — The coil sheds the heat the compressor pumps out of the box. Blanket it with dust, or box the cabinet in so the warm air it makes gets drawn straight back in, and the machine simply cannot reach its setpoint on a warm afternoon.
- A sealed-system fault: lost refrigerant or a failing compressor — This is the expensive answer and it is also the rarest. Diagnosing it properly means gauges on a sealed circuit, which is licensed work, so it is the last thing to suspect rather than the first.
- A stalled defrost cycle icing the evaporator over — Defrost failures do not announce themselves. The heater or its sensor gives up, frost accumulates until it bridges the fins, and from then on you have a cold block of ice with no air moving over it.
- A start relay or overload that will not bring the compressor up — A compressor that tries, clicks off, and tries again a few minutes later is being cut out by its overload. That is a starting-circuit fault, not a cooling fault, and it needs a technician.
Check in this order, and why
- Note whether the failure follows the weather — A cabinet that copes in the cool of the morning and loses it by mid-afternoon is short of heat rejection, not short of refrigerant.
- 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.
- Only then consider the control and the sealed system — They are last because they are the two that cost money to be wrong about.
Safety first
Safety
Treat the machine as live until it is unplugged or its breaker is off, and treat it as charged even then — a capacitor holds its charge after the power is off. Keep the door switch and every other interlock wired as you find them: each one stops something moving while a hand is inside. Leave every interlock and door switch exactly as you find it: each one cuts power to something for a reason.

When to call a technician
Where to stop: what you can see, reach and clear with the machine isolated is owner work; the sealed system, the compressor and anything that has to be measured rather than looked at is not. On this page that puts a sealed-system fault: lost refrigerant or a failing compressor on the far side of the line.
