The short answer for these models
Warm air inside a cabinet whose compressor is working is a distribution failure, not a production one. The three things that stop cold reaching the food — ice over the cold surface, a door that no longer grips, and a condenser with nowhere to put its heat — are all visible in a few minutes and none of them needs a tool. On the HC refrigerators the brand-level answer holds and the order does not: a plumbed cabinet has a second source of water and a second thing to fail, and a page that ignores which one you have sends you looking in the wrong place, so the water-path checks come before the rest on these models.
How this shows up
- Which form your HC unit is — settle this first — Check the back for a supply line. Fitted, and a leak has two possible sources; absent, and there is only one.
- Food near the cold source freezes while the rest stays warm — The split between frozen and warm tells you the cold is arriving in one place and going no further.
- The sides or the back of the cabinet are hot to the touch — The flanks or the rear are warm enough to notice, which means the heat being removed has nowhere to go.
Causes, most likely first on this family
- The thermostat, the sensor or the control — It sits below the mechanical causes because it is rarer, and because the checks above will have ruled most of it out by elimination. This is where the order departs from the brand-level page: on the HC models the construction settles it, so the water-path checks come before the checks that lead anywhere else.
- The sealed system or the compressor — Bottom of the list on purpose: it is the rarest of the five, the most expensive, and the only one that is not an owner check at any stage.
What to check first, and why that order
- First — shut the door on a strip of paper and pull — The paper test costs nothing and settles the cheapest cause before you move anything heavy. On these models this is the step the construction changes: what you found at the step above decides how much weight to give what you find here.
- Second — feel the condenser and the air around it — Reach behind or underneath. Dust you can lift off in a mat, or a cabinet jammed against the wall, is the cause and also the fix.
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. Defrost with time and open doors, never with a blade or a heat gun, because the evaporator tubing sits directly behind the ice. A refrigerator holds food safely at 40 °F (4 °C) or below, so move anything perishable to a cooler while you work rather than gambling on it.
Where the owner job ends
The owner half ends at the free checks. Once the seal grips, the vents are clear, the coil is clean and the thermostat is where it should be, whatever is left sits behind a panel or on the sealed side and needs a technician. Mention any frost pattern you found; it is the most useful thing you can hand over.
