The short answer
The faults that actually occur on a cabinet like this are led by the ones that block cold air and by the ones that let warm air in; the expensive failures are real but uncommon. On a Direct Supply refrigerator the class to know about first is "running but not cooling": it tops the list because it is the common endpoint of several different upstream faults. A facility machine is usually installed to a building standard, which makes the supply side well documented and moves suspicion onto the machine itself.
The classes, by observable
- Running but not cooling — It runs and runs, and the cabinet never gets back to where it should be. There is no Direct Supply refrigerator page for this one at present — the closest are listed below. Whether it happens constantly or in bursts changes the answer.
- No ice, slow ice or hollow cubes — The ice bin empties and does not refill, or the cubes come out small and hollow. There is no Direct Supply refrigerator page for this one at present — the closest are listed below. Check whether it happens every time or only sometimes.
- Dead — nothing runs at all — No light, no sound, no cold: the cabinet is completely inert. The page that carries the diagnosis is "DIRECT SUPPLY Refrigerator: Will Not Start or No Power". Note whether this is new or has always been there.
- Display, sensor and control complaints — A code on the display, a panel that will not respond, or a reading that the food plainly contradicts. No dedicated Direct Supply refrigerator page covers this class yet; the nearest pages are linked below. An appliance doing this is telling you where to start.
- Water inside or on the floor — Melt water under the bottom drawers, a ridge of ice on the freezer floor, or clean water arriving at the back. No dedicated Direct Supply refrigerator page covers this class yet; the nearest pages are linked below. If your unit does this, it narrows the list below immediately.
Frequency order
- Running but not cooling — Most frequent. It tops the list because it is the common endpoint of several different upstream faults. Read the position as qualitative. No counted corpus for this brand and appliance exists, so no denominator is quoted.
- No ice, slow ice or hollow cubes — Second most frequent. It belongs with the water path — valve, filter and fill tube — far more often than with the ice maker itself. It belongs at this position on a Direct Supply refrigerator and would move on a different platform.
- Dead — nothing runs at all — Third. Common, and usually cheap, because the whole path from the outlet to the motor can cause it. Rank it here on a Direct Supply refrigerator whatever a general troubleshooting list says.
- Display, sensor and control complaints — Fourth. A sensor, a lock state or a supply event explains most of these long before the board does. This is one of the answers a Direct Supply refrigerator owner can act on without a technician.
- Water inside or on the floor — Fifth. Defrost drains can close up given enough time. A Direct Supply refrigerator makes this easier to confirm than most, because the evidence is outside the cabinet.
The classes side by side
General guidance| Problem class | How often it comes up | Owner-fixable? |
|---|---|---|
| Running but not cooling | Leads the complaints | Often — airflow and defrost |
| No ice, slow ice or hollow cubes | Common | Often — supply and filter |
| Dead — nothing runs at all | Common | Often — supply and start device |
| Display, sensor and control complaints | Occasional | Sometimes — lock states and sensors |
| Water inside or on the floor | Occasional | Usually — the drain |

Safety first, and it is not a formality
Safety
Before anything else on a Direct Supply refrigerator, the rule that is not negotiable. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Behind the panels of a cold cabinet there is a sealed refrigerant circuit, and nothing on it is an owner repair. If you find oil on the tubing at the back, stop there: that is a sealed-system finding and it belongs to a technician. Clear ice with warm water and patience only — a heat gun or a sharp tool will reach the tubing behind it.
Owner fix or service call
Where an owner stops on a Direct Supply refrigerator is a line, not a judgement call. The condition is simple: if the next step needs a meter on live terminals or a gauge on the tubing, it is a service call. Everything on the owner side of this page is done with the power disconnected or with nothing opened at all.

What this page does not cover
Read this as the class-level answer for a Direct Supply refrigerator; anything more specific to your model lives on its own page. It is generalized across every family and model line: it names the problem classes and routes you onward, and carries no diagnostic procedure of its own. A page written for one Direct Supply refrigerator family beats this one wherever it exists, and it is linked from here rather than hidden. Left out on purpose: the model-specific figures — part numbers, wiring detail and the service-mode entry sequence — which are only correct for one family and would be wrong here.
