Which thermal effect occurs when a thermistor's self-heating exceeds its dissipation rate in an air-conditioning unit?

💡 Explanation

When a thermistor's self-heating rises above its heat dissipation capacity, Joule heating will occur within the thermistor due to the <I^2>R power dissipation exceeding the cooling rate resulting in the thermistor overheating, risking damage to close electronics. Therefore, component damage from Joule heating results, rather than thermal runaway, Peltier cooling, or Seebeck voltage that involve changes within rated performance conditions.
