The Hotpoint Dryer error F03 signifies a temperature sensing fault, often caused by a malfunctioning thermistor or NTC sensor. This error typically results in the dryer stopping mid-cycle, insufficient heating, or clothes remaining damp after the cycle ends. If you see the F03 code, it indicates that the dryer cannot accurately read its internal temperature, which may require inspection or replacement of the temperature sensor and associated wiring.

Common Symptoms:

  • Dryer stops mid‑cycle
  • Dryer not heating or insufficient heat
  • Clothes remain damp after cycle
  • F03 displayed on error code panel

Possible Causes

  • Faulty temperature sensor (thermistor/NTC) (medium)
