What this means on these models
On the 4w3n62 refrigerator this symptom is usually the damper that meters cold air from the freezer into the fresh-food side, because on this layout a stuck damper cools one compartment perfectly and starves the other. The 4w3n62 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 you observe on these models
- 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.
- The compressor never seems to stop — Continuous running without arriving at temperature is the same fault seen from the other side.
- 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 4w3n62 family
- Air damper between the compartments stuck or held shut — Ranked first on this family. It is the cause that a temperature reading in only one compartment will always mislead you about.
- Evaporator fan motor stalled, obstructed or worn out — Next, and close behind it. A fan that runs slow rather than not at all produces the worst version of the fault: partial cooling that looks like a thermostat problem.
- Condenser coil and condenser fan choked with dust — Next after those two. This one is the most common cause that owners can actually fix, and it is the one most often skipped because the coil is out of sight.
- Door gasket or door alignment letting warm air in — Fourth, and the least likely of the four. A gasket that has taken a set, or a door that has dropped on its hinge, leaves a gap that runs the compressor continuously and frosts the evaporator at the same time.
- Body: A brand-generic article on this symptom starts with the defrost cycle.
What to check first, and why that order
- Feel for airflow at the fresh-food vents with the door switch pressed — Cold air at the freezer vents but nothing at the upper vents moves the damper straight to the top of the list.
- Open the freezer and listen for the fan with the door switch held in — Press the door switch by hand.
- Pull the unit out and look at the condenser coil and its fan — Grey felt across the fins, or a fan blade turning through a mat of dust, is the whole diagnosis.
Before any panel comes off
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off.

When this becomes a service call
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. Call once the airflow and condenser checks are clean, because everything past them needs a meter and a panel off.
