Auseo KS Series Refrigerator is the scope of this page, and on it a cabinet that runs and will not get cold points first at a sealed-system fault: lost refrigerant or a failing compressor. Where the brand-generic article leads on a door gasket that has stopped sealing, this roster reverses the top two — the first check is the one you can reach on these cabinets without a teardown. 2 of the 4 causes below can be checked without a tool; the rest need a technician.
What you actually see
- It recovers overnight and loses it again by the afternoon — A cabinet that only fails when the room is warm is telling you about its clearance and its coil.
- 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.
- Sweating on the door frame or on the outside of the cabinet — Warm moist air is getting in past a seal, and the machine is fighting it every minute of the day.
- 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 KS series
- 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 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 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.
The order to work in
- 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.
- Feel the coil or the grille area at the back or under the kick panel — Warm means heat is being rejected. Cool on a cabinet that has been running for hours means it is not.
- 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.
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 a step needs a meter on live terminals, that is the end of owner work and the start of a service call.

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 sealed-system fault: lost refrigerant or a failing compressor on the far side of the line.
