The short answer
A 4w3n62 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 — The compressor hum is there; the air inside is not cold.
- 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.
- Ice cream goes soft while cubes still form — This is the earliest warning the cabinet gives.
- NEAR MISS — the unit is silent and nothing is cold — If nothing hums at all, stop here and start there instead.
Causes on the 4w3n62 listings, most likely 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. When the coil is furred over, the whole machine works harder and the cabinet simply never catches up on a warm day. The short revision run in the table above means these units left the line close together, so they wear at much the same rate.
- A door gasket that no longer seals — A gasket that has taken a set lets room air in continuously, which loads the evaporator with far more moisture than it was meant to shed. Check it with a sheet of paper: if it slides out without drag anywhere along the run, the seal is gone there.
- The condenser fan not running — A seized condenser fan gives you cooling that works overnight and fails by mid-afternoon. You can hear it at the back of the cabinet when the compressor is running.
- A failed start relay or overload — A failed start device looks like a dead compressor and usually is not.
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.
- 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.
- Confirm the damper between compartments opens — Worth doing early only when the freezer is cold and the fridge is not, and worth skipping entirely when both are warm.
- 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.
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. Call the same day if the compressor is hot enough that you cannot keep a hand on it, or if the breaker trips when it tries to start.
