Professional Repair Guide

What is this symptom?

Experiencing ice buildup in your Kenmore refrigerator? This common issue often manifests as frost accumulating in the freezer and refrigerator compartments.

Identifying the root cause is crucial to restoring optimal performance and preventing further damage.

Urgency: Medium

Important Tips for Kenmore Models

  • Kenmore refrigerators may have a drain strap or heater in some models to assist defrost drain clearing; its absence or failure can increase likelihood of freeze-ups.
  • Kenmore-specific troubleshooting includes checking defrost control board and evaporator fan motor as common parts to replace for frost issues.

Possible Causes

Faulty or inoperative defrost system (heater, thermostat, timer)

How to Identify: Excess frost on evaporator coils that doesn’t melt during normal defrost cycle, ice builds up repeatedly and defrost cycle not engaging.

Part: defrost heater / defrost thermostat / defrost control or timer

Door gasket or seal leaks allowing moist air ingress

How to Identify: Visible cracks, wear, or misaligned gasket; condensation around seals; moisture entering and freezing near door edges.

Part: door gasket (seal)

Warm, humid air ingress from frequent door openings or high humidity environment

How to Identify: Frequent door openings, high ambient humidity, moisture dripping inside then freezing.

Part: user behavior/environment
