Important Tips for Kenmore Models

  • Some Kenmore models include drain heater/strap that prevents freeze; check model manual to confirm presence and part number.

Possible Causes

Clogged defrost drain (ice or debris)

How to Identify: Ice buildup near the drain hole, water pooling in freezer bottom, water leaking into fridge bottom, visible blockage when inspecting drain hole

Part: defrost drain / drain line

Freezer temperature excessively low causing drain freeze

How to Identify: Freezer runs colder than normal, leading to regular ice blockage in drain even when clear

Part: temperature control thermostat / control board

Faulty or missing drain heater

How to Identify: Model has drain heater; repeated drain freezing even after clearing; heater shows no heat during defrost cycle

Part: drain heater or heater strap

Restricted airflow leading to uneven temperatures

How to Identify: Uneven cooling, other fridge sections too cold; ice buildup beyond drain area

Part: evaporator fan / vents
