Could a failing Freezer Door Gasket cause the GE GFE28GYNFS to have symptom: Frost Buildup In Freezer?

The gasket serves as the primary thermal barrier between ambient kitchen humidity and the sub-zero freezer environment. If the magnetic seal is compromised or the rubber has lost elasticity, warm air enters through the breach, and the moisture immediately freezes upon contact with the cold interior surfaces, creating 'snow' or frost buildup near the leak point.

Could a failing Defrost Thermistor cause the GE GFE28GYNFS to have symptom: Frost Buildup In Freezer?

This NTC (Negative Temperature Coefficient) sensor monitors the temperature of the evaporator coils to determine when to terminate the defrost heater cycle. If the sensor's resistance-to-temperature curve drifts, the control board may prematurely end the defrost cycle, allowing residual frost to remain on the coils, which eventually migrates into the freezer compartment as airflow is restricted.

Could a failing Defrost Drain Tube Grommet cause the GE GFE28GYNFS to have symptom: Frost Buildup In Freezer?

During a defrost cycle, melted ice must exit via the drain tube; however, GE 'duckbill' style grommets frequently clog with debris or bio-film. When water cannot exit, it refreezes at the base of the evaporator or in the drain pan, which increases the internal humidity levels significantly during the next cooling cycle, accelerating frost formation on all freezer surfaces.
