Can ambient conditions affect evaporator icing?

Yes. High kitchen humidity and higher ambient temperature can significantly increase evaporator frosting.

Common site factors that make icing more likely include:

Hot, humid prep areas, especially in summer or during heavy cooking.

Fridge positioned beside fryers, ovens, dishwashers, or pot-wash, where warm moist air is constant.

Poor ventilation around the unit, which can affect overall performance and recovery.

If you cannot move the fridge, focus on operating practice: keep door openings short, avoid loading warm product, allow space for air circulation, and keep gaskets clean and sealing properly.
