The symptom sequence on this Samsung RF32CG5400 in north Edmonton told a story before any panel came off: first the refrigerator made a terrible noise, then it stopped cooling. The control panel put a number on it — the fresh-food compartment sitting at 58°F. Here is how TechVill technician Kim worked from that to a confirmed diagnosis.

Step 1 — read the evaporator’s frost pattern. On a sealed-system failure, the coil frosts unevenly or barely at all. This coil’s frost pattern was good: the compressor and refrigerant loop were making cold exactly as designed. That single observation cleared the most expensive suspects — but a healthy coil in a warm fridge means the cold isn’t going anywhere. Something isn’t moving the air.
Step 2 — put a hand on the fan. The evaporator fan is what drives chilled air off the coil and into both compartments. Rather than condemning it from inference alone, Kim rotated the fan motor manually and felt it drag — sluggish, resisting, nothing like the free spin of a healthy motor. That mechanical drag also explains the “terrible noise” phase: a motor labouring against failing bearings gets loud before it gets slow.
Step 3 — connect the symptoms. A fan that can’t reach proper RPM can’t push enough air across the coils to cool either the fridge or the freezer effectively. One failing motor, both compartments degrading, coil blameless — every observation accounted for.

The fix on order:
- Evaporator fan motor (part #DA31-00342A) — Samsung OEM brushless DC (BLDC) fan motor; drives airflow across the evaporator into both compartments
Parts pricing has been requested from the supplier, with the quote to follow and the install visit to confirm airflow, RPM, and cooling in both compartments. The diagnostic lesson stands on its own: a frost pattern can look textbook-healthy and still be the key clue — what matters is knowing what each specific pattern rules in and out, then confirming with your hands, not just your eyes.
