Kenmore Refrigerator: water line freezing

Professional Repair Guide

What is this symptom?

Experiencing water line freezing in your Kenmore refrigerator? This issue can block water flow to your ice maker and dispenser, often caused by low temperatures, inadequate insulation, or improper routing of the water line. Look out for signs like no water output or intermittent flow, especially in cold conditions.

Urgency: Medium

Important Tips for Kenmore Models

  • Kenmore-specific troubleshooting often highlights checking line kinks and water connection issues first, similar to universal causes, but no official service bulletin on freezing lines was found.

Possible Causes

Low freezer or refrigerator temperature causing internal water line freezing

How to Identify: Line becomes blocked with ice when trying to dispense water or fill ice maker; freezer set much colder than recommended.

Part: Internal water supply line / fill tube

Insufficient insulation around the water line (especially inside doors)

How to Identify: Freezing occurs in cooler climates or with the line routed near cold air flow; symptoms are intermittent water flow that improves after warming the line. Users report this often in side‑by‑side models due to poor insulation. (Busted Refrigerator(Busted Refrigerator

Part: Water line insulation

Poor water pressure or slow flow increasing freeze risk

How to Identify: Reduced water flow from dispenser or ice maker, especially after long idle periods; pressure below manufacturer spec increases likelihood line freezes. (Busted Refrigerator8(Busted Refrigerator

Part: Water supply line / inlet valve

Kinks or improper routing of supply line restricting flow

How to Identify: Visible kinks or sharp bends in the line; occurs frequently behind unit; removing kinks often restores flow temporarily. (Busted Refrigerator
