Samsung Dryer: overheating

Professional Repair Guide

What is this symptom?

Is your Samsung dryer overheating? If you notice excessive heat during operation, external panels too hot to touch, or error codes like HE/HC, it's crucial to address this issue promptly. Overheating can lead to prolonged drying times, burning smells, and potential damage to your appliance. Understanding the common causes can help you troubleshoot effectively and ensure your dryer operates safely.

Urgency: High

Important Tips for Samsung Models

  • Samsung dryers may display HE/HC error codes indicating overheating or heat circuit issues, often linked to airflow or thermostat failures.

Possible Causes

Restricted airflow due to lint buildup or blocked venting

How to Identify: Dryer feels very hot, long dry times, weak airflow at exterior vent, visible lint inside vent or housing

Part: Lint filter, exhaust vent hose, ductwork

Faulty thermostat or thermistor

How to Identify: Dryer overheats even with clear vents and normal load; multimeter shows no continuity in thermostat/thermistor

Part: Cycling thermostat / thermistor / temperature sensors

Heating element malfunction (stuck or shorted)

How to Identify: Dryer overheats regardless of load size; element heating continuously; element resistance tests abnormal

Part: Heating element assembly

Drum or motor friction (mechanical resistance)

How to Identify: Dryer overheats with unusual noises; drum hard to turn by hand; overheating associated with motor strain

Part: Drum rollers, belt, idler pulley, bearings

Overloading reducing airflow

How to Identify: Symptom appears when large or heavy loads are dried; normal loads ok

Part: Drum load balance
