ARTT Freezer: Not Cooling or Not Freezing
A freezer that has warmed is a simpler machine than a refrigerator and the fault list is shorter: it has one compartment, one evaporator and no damper to distribute air, so when it stops holding temperature the candidates are the seal, the defrost circuit, the condenser and the room around it. Where a fridge-freezer can fail on air distribution, a standalone freezer usually cannot. The ARTT badge appears across several appliance categories, the signature of an importer badge applied to units from more than one source. The seal, the condenser, the loading and the room are all owner-checkable. The defrost circuit and the sealed system are not.
What the owner actually observes
- The contents have softened but the machine is still running.
- A thick sheet of ice has built up on the walls or the back panel rather than a light frost.
- The outside of the cabinet feels warm, or the machine runs continuously.
- Frost is forming around the door opening rather than inside.
- The appliance is in a garage or an unheated space and the problem is seasonal.
- Not this fault: If the cabinet is silent with no hum at all, the fault is power or start rather than cooling. That is a different fault — see ARTT Freezer: Controls, Display or Error Code (artt-freezer-control-fault).
- Not this fault: If it is cold enough but water is appearing, the drain is the suspect. That is a different fault — see ARTT Freezer: Water Leak (artt-freezer-water-leak).
Ranked for an ARTT freezer
- The door seal, or a door that is not closing square — Rank: first — Why ranked here: this leads on a standalone freezer because the temperature differential across the door is the largest of any appliance in the house, so a seal that leaks admits a continuous stream of humid air that both warms the cabinet and builds the ice that follows
- Ambient temperature and clearance where the freezer stands — Rank: second — Why ranked here: many freezers are rated for a limited ambient range, and a garage that drops cold in winter or bakes in summer takes the machine outside what it was designed to work against
- A procedure or part borrowed from another appliance of the same badge — Rank: third — Why ranked here: ranked here because a badge that spans several appliance categories is applied to units from different sources, so a genuine fix for one of them can be actively wrong for this one
- A condenser choked with dust, or a stalled condenser fan — Rank: fourth — Why ranked here: the cabinet can only reject heat as fast as air crosses the condenser, and in the places freezers usually live — garages, basements, utility rooms — the coil silts up faster than in a kitchen
- Loading — a large warm load, a door left ajar, or the cabinet packed to the lid — Rank: fifth — Why ranked here: a chest or upright freezer packed solid restricts what little air movement it has, and a batch of warm food raises the whole cabinet for a day or more
- A defrost failure icing the evaporator on a frost-free model — Rank: sixth — Why ranked here: frost-free freezers have the same defrost circuit as a refrigerator, and when it fails the coil packs with ice and the machine runs without cooling
- Note: Because this badge spans multiple appliance categories and therefore multiple sources, the order below assumes nothing transfers: no fix, part number or procedure from another ARTT machine is treated as evidence about this one.
Check in this order
- The seal with a strip of paper closed in the door at several points around the frame — Order: first — Because: it is free, it takes minutes, and on a freezer a marginal seal produces exactly this complaint
- How hot or cold the space gets, and whether the machine has clearance behind and above it — Order: second — Because: a seasonal fault is an ambient fault, and no part replacement will change it
- The condenser coil and its fan at the back or beneath, with the machine unplugged — Order: third — Because: it is the cheapest correction available and it explains a machine that runs constantly without gaining
Owner-safe checks
- Establish what this specific unit is. Read the data plate for the model, the serial and — importantly — the manufacturer or importer line, then work only from what that plate says. Do not carry over a fix from another appliance that happens to wear the same badge. — Step: first — Tools: a torch and a phone camera — Time estimate: a few minutes
- Put a thermometer in the cabinet, between packages rather than in open air, and read it after several hours. A freezer holds food safely at 0 °F (−18 °C) or below, and that is the standard to judge it against. — Step: second — Tools: a freezer thermometer — Time estimate: a few minutes, then several hours
- Test the seal with a strip of paper closed in the door at several points round the frame, and look for ice forming around the opening, which is a seal leaking rather than a machine failing. — Step: third — Tools: a strip of paper, a torch — Time estimate: under a quarter of an hour
- Unplug the machine and clean the condenser coil and its fan at the back or underneath, and pull the cabinet out far enough to give it clearance behind and above. — Step: fourth — Tools: a vacuum with a brush head, a screwdriver — Time estimate: under a quarter of an hour
- If ice has built up in a sheet, empty the cabinet into a cooler, unplug it and let it defrost completely with towels down, then restart it and watch whether the ice returns within days. — Step: fifth — Tools: a cooler, towels — Time estimate: a day
- Record the model, serial and manufacturer line from the data plate, and treat that — not the badge — as the identity of the machine for the whole job, including when you order a part. — Step: sixth — Tools: a phone camera — Time estimate: a few minutes
- Stop condition: Stop before testing the defrost circuit, the fan or the thermostat with a meter — those are live tests inside the cabinet.
Safety
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. A freezer holds a sealed refrigerant charge and a compressor with a start capacitor, and a chest freezer lid is heavy enough to injure. Never chip ice off an evaporator or a cabinet wall with a sharp tool; the tubing runs immediately behind the surface you are hitting. Judge food that has been above freezing by how long it was warm rather than by how it looks. A freezer holds food safely at 0 °F (−18 °C) or below.

When to call a technician
The line is the defrost circuit and the sealed system. Call if ice returns within days of a complete manual defrost, which points at the defrost circuit. Call if the cabinet never reaches 0 °F (−18 °C) after the seal, condenser and clearance have all been corrected. Call if the compressor is silent or clicks and stops repeatedly. Call immediately if there is an oily residue on the tubing at the back.

What this page does not cover
This page is generalized across every family and model sold under the ARTT badge. It does not carry model-specific error-code tables, family-specific service procedures, sealed-system work or parts numbers, and no model-specific page exists beneath it yet — the data plate on your unit is the authority, not this page. For the other faults on this appliance, start from Common ARTT Freezer Problems (artt-freezer-problems) and pick the symptom that matches.
