Maytag Refrigerator: frost buildup and cooling failure

Professional Repair Guide

What is this symptom?

If you're experiencing frost buildup and cooling failure in your Maytag refrigerator, you may notice excessive ice forming on the evaporator coils or back walls. This problem can lead to reduced cooling efficiency in both the freezer and refrigerator compartments, affecting food preservation and freshness.
