Important Tips for Kenmore Models

  • Kenmore-specific troubleshooting mirrors universal causes but repair parts (heating element, thermostats, blower wheel) should be model-specific.
  • Control board or timer short causing continuous heat is rare but noted in Kenmore-specific guides

Possible Causes

Restricted airflow due to clogged vent/duct or lint buildup

How to Identify: Exterior very hot to touch, reduced airflow at outside vent, long dry times, visible lint buildup in vent or lint filter housing

Part: Exhaust vent, lint filter, ductwork

Defective cycling thermostat or temperature sensor

How to Identify: Dryer doesn’t cycle heat properly, runs hot continuously; multimeter test shows improper continuity changes with temperature

Part: Cycling thermostat/thermistor

Blocked or malfunctioning blower wheel impeding airflow

How to Identify: Weak airflow from outside vent, blower wheel obstruction or wobble on shaft

Part: Blower wheel

Control board or timer short sending continuous voltage to heating circuit

How to Identify: Heating stays on regardless of cycle settings; inspection shows burnt or shorted components on board

Part: Main control board or timer
