The short answer
When the ARV line will not cool, the fault is usually in the path the cold air takes rather than in the machine that makes it. This family is a short list of model numbers rather than a whole range. Work the path from the door inwards and the expensive cause is the one you reach last, not first.
What an owner actually sees
- Warm air at the vent when you hold a hand in front of it — Air moving but not cold means the evaporator is not taking heat out; no air at all means it is blocked or the fan has stopped.
- The thermometer disagrees with the display or dial — A control reading its sensor wrongly, or a sensor that has lost contact with its mount. Trust the thermometer, not the panel.
- The cabinet is warm while the compressor is clearly running — You can hear or feel the unit working, yet nothing inside comes down to temperature. That pairing rules out most no-power faults before you touch anything.
- NEAR MISS — the cabinet is silent and nothing is cold — Silence changes the question entirely: that is a no-power, start-device or control fault, and it belongs on a different page.
Causes, most likely first on the ARV line
- A defrost cycle that has stalled and iced the evaporator — First on the ARV line. A defrost cycle that runs short rather than failing outright leaves a little ice behind each time, and it builds over weeks until it fills the air path.
- Evaporator fan not turning — Second, and it looks identical from the outside. The fan is the part that moves cold out of the evaporator compartment, and on these cabinets it is the item most likely to be stopped by ice rather than by its own failure — clear the ice and the fan question answers itself.
- Door seal and door alignment — Third. A seal that has taken a set lets a slow stream of room air in, which loads the evaporator with moisture and feeds the ice at the top of this list.
- Dust or clearance at the condenser — Fourth, and it is the cause that produces the seasonal version of this complaint: fine all winter, warm in summer. Clearance and dust are owner-checkable without opening anything.
- Sealed system or compressor — Last. It is the expensive answer and the least likely one, so it should be reached by elimination and never assumed from the symptom alone.
Check in this order, and why
- Walk the door seal by eye and by hand — Look along the closed door for daylight and feel for cold spilling out at the bottom corners.
- Pull the cabinet out and look at the back and the clearance — Placement is checked here because it explains the seasonal version of this complaint better than anything inside.
- Listen at the freezer section for the internal fan — Placed after the free checks because it is the first step that needs a panel or a door switch held.
- Only then consider the compressor side — By this point three cheaper causes are eliminated, which is the whole reason for the order.
Before you open anything
Safety
Power off at the breaker or the plug before any cover comes off, and treat the compressor area as live until it is. Sharp edges and a fan blade sit immediately behind most covers on cabinets of this build, so work with the power isolated rather than with the door switch propped. Refrigerant work is licensed work and is out of scope for an owner. A refrigerator holds food safely at 40 °F (4 °C) or below, and a freezer at 0 °F (−18 °C) or below. If the cabinet has been above that and you do not know for how long, the safe assumption is the worst one. Keep the door closed while you work — every opening costs cold you cannot put back quickly.

When to call a technician
Call once the owner-side checks are clean: seal, loading, clearance and a visible look at the evaporator area. Call immediately if you see oil at the compressor or smell burning, because oil outside the tubing means the sealed system is open and every further hour of running makes the repair larger.
