Samsung Dryer Error Code AE
Communication error — internal signal failure
The most common cause of the AE error on a Samsung dryer is inter-board wiring harness loose or unseated (~50% of cases); start with: power cycle the dryer.
What Does Error Code AE Mean on a Samsung Dryer?
Communication error — internal signal failure.
The main control board and a sub-board (display or motor controller) have stopped exchanging signals, so the dryer freezes mid-cycle or won't accept commands. A loose ribbon/harness between the boards or connector corrosion from laundry-room humidity is the usual cause, not a dead board.
