Does the sub-zero fridge have a frost-free feature to prevent ice buildup?

Yes, Sub-Zero fridges typically have a frost-free feature to prevent ice buildup. This feature is commonly found in modern refrigerators and is crucial for ensuring optimal cooling performance and convenience. The frost-free technology uses a combination of advanced insulation, precise temperature control, and automatic defrosting cycles to prevent ice accumulation on the refrigerator's evaporator coils and walls. By periodically melting any ice or frost that forms during normal operation, the frost-free feature eliminates the need for manual defrosting, allowing the fridge to maintain consistent temperature levels, preserve food quality, and reduce maintenance efforts for the user.
