  • Temperature regulation appears incorrect, e.g., overheating protection triggered
  • Unit may cycle off frequently without reaching set temperature

Possible Causes

  • Temperature sensor failure or disconnection (medium)
  • Internal temperature reading anomaly due to airflow or heat buildup (low)
