What Does Error PF Mean?

The Black+Decker air conditioner PF error indicates a power failure, typically caused by a malfunctioning internal temperature sensor (thermistor/probe). This error may prevent the unit from cooling, cause it to stop responding, and display PF on the control panel. In some cases, buttons may become unresponsive as well. If this error persists after a reset, it suggests a deeper sensor issue requiring professional diagnosis and potential replacement.

Common Symptoms:

  • Unit displays PF on control panel
  • Unit may stop cooling or not turn on
  • Buttons may become unresponsive (reported in some cases)

Possible Causes

  • Internal temperature sensor (probe/thermistor) failure or disconnection (medium)
  • Control board detecting sensor fault leading to shutdown (medium)
