Kenmore Dryer: not drying on low heat

Professional Repair Guide

What is this symptom?

If your Kenmore dryer is running but clothes remain damp after a low heat cycle, it's possible that the heat is insufficient due to issues like a clogged vent, faulty heating element, or a blown thermal fuse. These problems can lead to extended drying times and persistently wet clothes, making it essential to identify and address the underlying causes.

Urgency: Medium

Important Tips for Kenmore Models

  • Some Kenmore models use moisture sensors that can misread moisture if dirty, causing premature cycle end.

Possible Causes

Restricted or clogged venting system

How to Identify: Airflow weak at exterior vent; excessive lint buildup behind dryer; long drying times even with small loads.

Part: Dryer exhaust vent / duct

Faulty or weak heating element

How to Identify: No or low heat being produced; test for electrical continuity with a multimeter shows open circuit.

Part: Dryer heating element

Blown thermal fuse

How to Identify: Dryer runs but heating cycle is disabled; continuity test on thermal fuse fails.

Part: Thermal fuse

Faulty thermostat or temperature sensor

How to Identify: Inconsistent or incorrect cycling of heat during the drying cycle; multimeter testing shows thermostat malfunction.

Part: Thermostat / temperature control

Dirty moisture sensor

How to Identify: Dryer ends cycle prematurely even with damp clothes; visible lint/debris on sensor bars.

Part: Moisture sensor
