The short answer
The WHS roster spans several capacity cores rather than one, so the cabinets it covers differ in how far air and meltwater have to travel inside them, and the capacity core carried in each code is what separates one entry on it from the next. When one compartment is cold and the other is not, the cabinet has an airflow problem rather than a cooling problem, because on cabinets of this kind the cold is made in one place and moved to the other. That single observation redirects the whole diagnosis.
What you observe on these models
- The compressor never cycles off — The cabinet is no longer reaching its set point, so the control never tells it to stop. This is the clearest sign that a restriction is at work.
- Food is spoiling faster than it should even though the cabinet feels cool — Cool is not cold. A cabinet can feel acceptable to the hand and still sit above the safe storage threshold all day.
- Condensation or ice along the door seal — Warm humid room air arriving where the seal is not closing. The frost marks the leak, which makes it the most self-diagnosing symptom on this list.
- It recovers after being emptied and drifts again once refilled — A cabinet short of capacity rather than broken, which points at airflow, seal or condenser rather than at the compressor.
Causes, most likely first on the WHS line
- Frosted evaporator blocking the air path — Ranked first on this roster: frost builds quietly over weeks, which is why owners notice the temperature rather than the ice that caused it.
- Vents blocked by stored food or an overfilled shelf — Ranked second on this roster: cold air has to reach the compartment through specific openings, and a shelf packed to the back wall closes them as effectively as a failed fan would.
- Door seal not closing, or a door left ajar — It ranks third here because the paper test confirms it in a minute and because the frost pattern along the seal names the cause for you.
- Start components or the sealed system — Ranked last on this roster: reaching it honestly is a useful result, because it turns the question into repair or replace rather than keep looking.
- Body: The ranking here keeps the brand-generic order, and what the WHS line changes is the order of the checks beneath it: the roster spans several capacity cores, and a longer cabinet has a longer air path and a longer run to its drain.
Check in this order, and why
- Look at the rear interior wall for a frost sheet — A layer thick enough to hide the surface underneath explains the complaint on its own, and it means the defrost side is worth investigating.
- Clear the back of every shelf and find the vents — Leave a hand's width clear at the rear of each shelf, then give the cabinet a day before judging.
- Close the door on a strip of paper at several points and pull — Anywhere the paper slides out freely is admitting air. Check the whole perimeter, not just the handle side.
- Have the circuit assessed rather than guessed at — This needs gauges and a licence. Oil on the tubing at the back means the circuit is already open and it should stop running.
Before you open anything
Safety
Unplug the cabinet or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. Never chip frost off the rear interior wall with a sharp tool, because the tubing behind it is thin-walled and a nicked tube turns a defrost into a replacement. A refrigerator holds food safely at 40 °F (4 °C) or below, so move anything perishable to a cooler before you start rather than after.

When to call a technician
Call when a full defrost, a cleared condenser and a clean paper test have all failed to hold the cabinet for a day, because that pattern eliminates everything an owner can reach. Call sooner if only one compartment is affected and the vents are already clear, because a damper or an interior fan needs a panel off. Either way, move the perishable load first: it will not survive the diagnosis.
