The short answer first
On the 4w3in62 refrigerator this symptom is usually a defrost circuit that stalls quietly rather than failing outright, so the evaporator ices, airflow stops and the cabinet warms while the compressor keeps running. The 4w3in62 family is one platform carried across a run of revisions, and the trailing digits of the model number are what separate them: the fault set is shared, the part numbers are not.
What an owner actually sees
- The panel reads a normal temperature that the cabinet plainly is not — A displayed number that disagrees with a thermometer left inside is a reading problem, not a cooling problem.
- The cabinet is warm but the unit is clearly running — The compressor hum is there and the air inside is not cold — the combination that separates this fault from a dead machine.
- The freezer holds but the fresh-food side does not — On these models the split tells you the problem is in how air is moved or metered, not in how cold is made.
- Frost builds as a sheet on the freezer rear wall — A solid white panel rather than the usual light dusting over the coil area.
- NEAR MISS — the unit is silent and nothing is cold — No hum, no fan and no lights means a power, relay or board fault, and that belongs on the will-not-start page rather than this one.
Causes, most likely first on the 4w3in62 family
- Defrost cycle stalled and the evaporator iced over — Top of the list here. Ice on the evaporator blocks the only path cold air has into the cabinet, so the run time climbs while the air moves less and less.
- Main control board or inverter not commanding the compressor — Second here. When the board or the inverter stops commanding, everything else in the cabinet behaves normally and only the cooling is missing.
- Compressor start relay or overload protector — Third on this platform. Ranking it above the sealed system is the difference between a cheap part and a written-off cabinet.
- Sealed system: refrigerant loss or a failed compressor — Fourth: possible, but not where to start. A system that has lost charge runs constantly and cools a little or not at all; a failed compressor hums and stops.
- Body: A brand-generic article on this symptom starts with the defrost cycle, and so does this one.
The order to work in
- Take the freezer rear panel off and look at the evaporator coil — A solid sheet across the coil instead of an even light dusting confirms it; a clear coil rules the cause out in one look.
- Watch whether the compressor ever starts at all over a full cycle — Cold tubing at the condenser and a silent compressor with power present is what sends this to a technician.
- Listen at the compressor for a click every few minutes with no run — A repeating click and hum with no sustained run is the relay pattern and it is worth a technician visit before anything drastic.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off.

Where the owner fix stops
Call immediately if you smell burning, see oil at the compressor or see scorch marks at a connector — oil outside the tubing means the system is open and every hour of running makes it worse. A refrigerator holds food safely at 40 degrees Fahrenheit, which is 4 degrees Celsius, or below, so if the cabinet has been above that overnight, deal with the food before you deal with the appliance.
