Could a failing Freezer Door Gasket cause the SAMSUNG RF27T5201 to have symptom: Frost Buildup In Freezer?

Frost is often the result of ambient, humid air entering the freezer through a compromised thermal envelope. If the magnetic seal has lost its elasticity or has a visible gap, vapor undergoes deposition directly onto cold surfaces, forming ice crystals. This part restores the airtight seal required to maintain a dry, sub-zero environment.

Could a failing Defrost Thermistor cause the SAMSUNG RF27T5201 to have symptom: Frost Buildup In Freezer?

This sensor monitors the temperature of the evaporator coils to determine when to end the defrost cycle. If the thermistor provides incorrect resistance values to the control board, the system may skip defrost cycles entirely or end them prematurely. This leads to ice bridging on the coils which eventually migrates into the freezer cabin as frost.

Could a failing Evaporator Drain Clip (Enhanced) cause the SAMSUNG RF27T5201 to have symptom: Frost Buildup In Freezer?

The original drain clip often fails to transfer enough thermal energy from the defrost heater into the drain port. When the drain hole freezes shut, meltwater from the defrost cycle cannot exit the unit and instead refreezes at the base of the evaporator. Over time, this ice mass causes high-humidity conditions inside the freezer, leading to secondary frost buildup on the walls and drawers.
