The quick verdict
An Artt refrigerator that runs but does not cool has usually lost its defrost cycle, so ice has built across the evaporator and blocked the airflow that feeds the fresh-food compartment. A full manual defrost is the diagnostic test: if cooling returns afterwards, the defrost system is the fault, and that finding is what the technician needs.
How this shows up
- Fresh food warm while the freezer stays cold — The airflow signature of a blocked evaporator.
- A sheet of frost across the freezer rear wall — The blockage itself, visible through the vents.
- Cooling that returns after the unit is switched off for a day — Close to conclusive for a defrost fault.
- Water pooling under the crisper — A blocked defrost drain, which is often the same story at a different stage.
- NEAR MISS: vents blocked by packed food — Air cannot reach the compartment if the outlets are covered.
Likely causes on this brand
- Defrost heater or its control failed — First, because the whole frost-free arrangement depends on it and it fails silently.
- Defrost drain blocked — Second, and it produces water rather than warmth until the ice takes over.
- Evaporator fan not running — Third, and it gives the same warm-forward pattern without the frost sheet.
- Door seal admitting humid air — Fourth, and it is the upstream cause that overwhelms a working defrost cycle.
- Sealed system — Last, and the least likely.
Check them in this order
- Check the vents inside are not blocked by food — Free, instant, and a genuine cause.
- Look through the freezer vents for a frost sheet — It is usually visible without removing anything.
- Listen for the evaporator fan — It separates an iced coil from a dead fan.
- Defrost fully and see whether cooling returns — The definitive owner-level test.
Owner-side checks, step by step
- Move perishables into a cooler with ice — A refrigerator holds food safely at 40 degrees Fahrenheit or below, which is why this comes first.
Tools: cooler, iceAbout 20 min
- Empty the cabinet and leave both doors open overnight — Towels on the floor. Warm air and time only, never a sharp tool or a heat gun.
Tools: towelsAbout 120 min
- Restore power and log both compartments for a day — Cooling that returns and then degrades again over the following weeks confirms the defrost system.

- Clear the defrost drain if you can reach it from inside — Warm water down the drain hole in the freezer floor, gently. Stop here rather than removing the evaporator cover.

The hazard on this machine
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off, and the defrost heater sits immediately behind the panel most people want to remove. Never chip, scrape or hack at ice on an evaporator: the tubing is directly behind it, and puncturing it ends the appliance and releases refrigerant into the room. Do not aim a heat gun at the coil either; the plastics and the tubing both suffer.
The line for a service call
Call when cooling returns after a defrost and then fails again, because that is the defrost system telling you clearly what is wrong and the repair is behind the evaporator cover. Call promptly if both compartments are warm with the compressor running continuously, which is a different and more urgent branch. Tell the technician about the defrost test and its result: it saves diagnostic time and it is exactly the evidence they want.

Scope of this page
This page is the class-level answer for an Artt refrigerator that will not cool. It publishes no defrost intervals, heater ratings, refrigerant data or part numbers, because those differ between builds under this badge and sealed-system data is not owner information. Where a family- or model-specific page exists it carries the defrost layout for that unit. Refrigerant handling is regulated work and stays outside this page entirely.
