Kenmore Dryer: weird noise and overheating
What is this symptom?
Is your Kenmore dryer making weird noises like squealing or grinding, and feeling excessively hot during operation? These symptoms often indicate airflow restrictions or worn drum support components, leading to longer drying times and potential overheating. Address these issues promptly to ensure efficient and safe dryer performance.
Important Tips for Kenmore Models
- Kenmore dryers may have specific thermistor and cycling thermostat parts; use model-specific part numbers
Possible Causes
Restricted airflow (vent or lint blockage)
How to Identify: Very hot cabinet/air exhaust combined with long dry times; poor air flow at external vent; visible lint buildup
Part: Dryer vent system, lint trap, exhaust duct
Worn or failing drum support components leading to noise
How to Identify: Noise patterns: squealing or rumbling when drum turns; uneven rotation; increased noise over time
Part: Drum support rollers, drum glides/pads, idler pulley
Worn or damaged drive belt or belt assembly
How to Identify: Slapping or rattling noise; belt fray visible on inspection; inefficient rotation
Part: Drive belt
Blower wheel obstruction/damage
How to Identify: Noise (vibration or humming, reduced airflow, overheating due to poor air movement
Part: Blower wheel
Faulty heating control components (thermostat/thermistor)
How to Identify: Dryer overheats without airflow issues; temp regulation fails; tested out of spec with multimeter
Part: Cycling thermostat, thermistor
Faulty drive motor or bearings
How to Identify: Grinding or loud mechanical noise; dryer stops and restarts after cooling; resistance when manually turning drum
Part: Drive motor
Heating element stuck on or shorted
How to Identify: Excessive heat even with good airflow; scorching smell or scorched clothes; thermostat not regulating
Part: Heating element assembly
