What Does Error F3 Mean?

The Haier dryer error code F3 indicates a malfunctioning temperature sensor, often caused by a faulty or shorted exhaust thermistor or filter sensor. This error typically results in the dryer failing to heat properly or stopping unexpectedly during drying cycles, particularly after a lint filter check. To resolve this issue, ensure the lint filter is clean and properly seated, as debris can affect sensor readings.

Common Symptoms:

  • Dryer stops heating or cycle halts unexpectedly when F3 is displayed
  • Error appears during drying cycles, often after lint filter check

Possible Causes

  • Faulty or shorted filter sensor (exhaust/thermistor) (medium)
  • Dirty or improperly seated lint filter impacting sensor reading (medium)
