The short answer
A 4w3g80 cabinet that runs warm is an airflow problem until the model matrix says otherwise. Where the brand-generic page opens with the sealed system, this one opens with the defrost path, because that is what the listings in this family share.
What you actually observe
- The cabinet is warm while the unit is clearly running — You can hear it working and feel nothing for it.
- The compressor never cycles off — A healthy unit is quiet for part of every hour.
- Air at the vents is moving but not cold — Hold a hand at the outlet between the compartments and you feel the draught without the chill.
- NEAR MISS — the unit is silent and nothing is cold — That is a no-power or start-relay fault and it is a different page.
Causes on the 4w3g80 listings, most likely first
- Evaporator fan motor failure — The fan sits behind the freezer rear panel and is the moving part that wears on this platform. The long revision run above covers a lot of production, and the oldest listings in it reach this point first.
- A condenser coil packed with dust — A blanketed condenser cannot reject heat, so the compressor runs longer and longer for less and less cooling.
- A thermistor reading the wrong temperature — Thermistor drift is a slow fault and is usually diagnosed by the gap between the setting and what a glass of water in the cabinet actually measures.
- The condenser fan not running — When this fan stops, the compressor cycles on its overload rather than on the thermostat, so the pattern is long silences between short runs.
Check in this order, and why
- Listen at the freezer for the evaporator fan — Hold the door switch in so the fan is allowed to run; it separates the two likeliest causes before any tool comes out. Silence with the switch held is a result, not a non-result.
- Look at the freezer rear panel for frost — If the fan runs and the coil is iced, the defrost path is your fault and the fan is a bystander. Frost at the vent slots counts, even if you cannot see the coil.
- Check the door seals with a sheet of paper — Do it at four points on each door rather than one; gaskets fail in patches. A sheet that pulls out with no drag marks the spot.
- Leave a thermometer in the cabinet overnight — A single reading tells you little; a reading taken after the door has been shut for hours tells you whether the control is lying. Use a glass of water so the reading is not chasing the door.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Never chip frost off an evaporator with a screwdriver or a knife: the tubing behind it is thin-walled, and one puncture turns a free defrost into a sealed-system repair.

When to call a technician
The line on these models is the rear freezer panel: everything in front of it is an owner check, everything behind it needs the evaporator exposed and a way to read it. If the fan is silent with the door switch held in, that is a parts job rather than a diagnosis.
