The short answer
Every model in the HD roster shares one capacity core and differs only in finish or trim, so the cabinet behind them is the same machine throughout, and each entry carries a bracketed chassis reference alongside the model code, so the full code and not the family name is what identifies a part. 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
- 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.
- The cabinet is warm but clearly running — The compressor hum is there and the air inside is not cold. A running cabinet that will not cool is reporting a restriction, not a failure.
Causes, most likely first on the HD 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.
- Evaporator fan not running — It ranks third here because it needs a panel off to confirm, but the symptom pattern is distinctive enough to suspect it before opening anything.
- 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 HD line changes is the order of the checks beneath it: every cabinet in this roster is mechanically the same, so what genuinely varies across it is where each one has been installed.
Check in this order, and why
- Read the whole code, bracketed chassis reference included — Entries on this roster carry a chassis reference alongside the model code, and the reference is what a part is matched to. Take it from the rating plate before you start, not afterwards.
- 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.
- Listen for the fan with the door switch held in — Press the door switch and listen inside. Silence where there should be airflow points at the fan or its supply.
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.
