A AUFSS freezer that is warming while clearly still running is reporting an airflow or a heat-rejection problem in most cases. This page covers a single listing, AUFSS210ETH-LK. Where the brand-generic article opens at the compressor, on a dedicated freezer the door seal and the frost pattern come first, because both are free and both are more often responsible.
What you observe
- Contents softening while the cabinet still feels cold — A freezer holds food safely at 0 degrees Fahrenheit or below. A compartment a few degrees above that still feels frozen to a hand.
- The unit runs continuously and never cycles off — Running without reaching a set point is the same fault seen from the other side, and it is what makes a cheap fault expensive if left.
- Heavy frost on the door seal or around the opening — Warm moist air is entering continuously. A sealing problem, and also the source of the ice that blocks the coil.
- NEAR MISS - the unit is silent and nothing is cold — That is a no-power, relay or control fault rather than an airflow fault, and it is a different diagnosis.
Causes, most likely first on this roster
- Frost across the evaporator blocking airflow — The tell is a solid frost sheet rather than a dusting, plus a compartment that recovers for a day after a manual defrost. Across the AUFSS listings this is one finding rather than several.
- Door seal, hinge alignment or a door held ajar — A seal that has taken a set, or a package holding the door fractionally open, admits warm moist air continuously - which both warms the cabinet and feeds the coil the moisture that ices it. On AUFSS210ETH-LK, as on every other number in the AUFSS table, this is where a technician starts.
- Ambient conditions outside the control range — Ranked here because it explains seasonal complaints with nothing broken at all, and no part will change it. Treat this as a AUFSS-wide finding, and treat the table above as the parts authority.
- Compressor, start relay or sealed-system fault — Last, deliberately. It is the least likely cause of a warming freezer and the only one that is not an owner fix; refrigerant work is licensed work.
- Body: The ranking here moves the door seal above the condenser, which is a departure from the brand-generic order. A dedicated freezer is opened rarely but loaded heavily, and a seal held off by a package produces both the warming and the ice that follows it.
The order to work in
- Put a thermometer in the compartment and wait — A freezer holds food safely at 0 degrees Fahrenheit or below. A hand cannot measure the few degrees that matter here.
- Look at the rear wall for a frost sheet — A solid layer rather than a dusting is the most informative thing visible without removing a fastener.
- Check nothing is holding the door fractionally open — An overfilled basket or a package proud of the shelf line costs a freezer more than almost anything else.
- Body: This sequence is set by access: everything visible with the door open comes before anything needing the unit moved, and the coil panel comes last because reaching it means emptying the cabinet.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Never chip ice off the evaporator with a screwdriver or a knife: the fins are thin-walled and a punctured coil turns a defrost problem into a sealed-system replacement.

Where the owner line is
Call once the thermometer, the seal and the condenser area are all confirmed good and the compartment is still warming. On the AUFSS roster the next step is the coil panel, which means an emptied cabinet and exposed fins. Call immediately if there is oil in the machine compartment.
