Kitchenaid Refrigerator: ice buildup

Professional Repair Guide

What is this symptom?

Experiencing ice buildup in your KitchenAid refrigerator? This issue often manifests as excessive frost or ice accumulation on walls, vents, or floors of the fridge or freezer, particularly after frequent door openings or over time. Common causes include warm, humid air entering due to a faulty door gasket or a blocked defrost drain, both of which can lead to moisture freezing inside your appliance.
