The short answer
The K line distributes its cold through a single duct, so on the models listed in the table on this page a fault anywhere along it warms one compartment and leaves the other perfect. That split is the first thing to read and it decides the whole diagnosis.
The symptoms, and their near misses
- The fresh-food side is warm but the freezer is still hard — The classic airflow split: cold is being made and is not being delivered. Look at the duct and the damper before anything else.
- Food in the fresh-food section spoils faster than it used to — Milk turning early is often the first symptom an owner notices, well before a thermometer is reached for. On the models listed in the table on this page the access for this is the same across the line.
- The freezer is over-cold while the fridge is warm — Extreme temperatures in opposite directions is the classic damper signature.
- Both compartments are warm and the compressor runs constantly — The machine is making no useful cold at all. This is the pattern that eventually points at the sealed system.
- The cabinet feels warm to the touch at the sides — Some warmth is normal where the condenser tubing runs in the shell; heat you cannot keep a hand on is not.
- NEAR MISS — only the ice maker has stopped — If the food is cold, the cooling system is fine. Go to the ice page.
- NEAR MISS — the cabinet is silent and nothing is cold — Silence is a different diagnosis entirely: nothing is trying to cool, so start with the supply and the controls.
The ranking that matters
- A thermostat or sensor reading the wrong temperature — Top of the list here. A sensor that has drifted or come adrift from its clip reports a cabinet that is colder than it is, and the machine stops cooling early. That holds for every model the table on this page lists.
- A cabinet with no clearance at the back or top — Then this. Clearance is part of the specification, not a nicety. Without it the coil cannot reject heat at all.
- A door seal that no longer closes the cabinet — Third in the order. A continuous leak of room air both warms the cabinet and feeds the frost that blocks the coil, so it produces two faults for the price of one. On the models listed in the table on this page this is the check that decides the job.
- Overloading and blocked internal air vents — Less common than the three above. Airflow inside the cabinet is as important as airflow outside it. A full cabinet with blocked vents underperforms an empty one every time.
- A dirty or blocked condenser coil — Near the bottom of the list. Dust, pet hair and lint insulate the coil precisely where heat must leave. In a warm room that alone is enough to push a healthy cabinet above temperature.
Check in this order, and why
- Listen at the freezer for the evaporator fan — With the door switch held in, listen for airflow. Its presence or absence separates the two likeliest causes.
- Ask when the cabinet was last moved — A recent move with a short standing time explains days of poor performance that then resolves on its own. It is one of the few places the models listed in the table on this page genuinely diverge.
- Look at the freezer rear panel for a frost sheet — Frost is the evidence: heavy, flat and covering the fan opening means the coil is blocked.
- Check the clearance around the cabinet — A hand-width at the back and a clear top. Recirculating warm air is a common and invisible cause.
Isolate it first
Safety
Isolate the machine first. Unplug it or switch off its breaker before any cover comes off, and give a few minutes before touching anything behind the machine compartment cover. Never put a blade to ice inside the cabinet — the evaporator tubing is directly behind the liner, and a pierced tube turns a cheap job into a sealed-system repair.

Where the owner line is
Call when the compressor runs continuously and the condenser stays cool to the touch: that combination points at the sealed system, and every hour it runs in that state makes the repair larger.
