Samsung Dryer Error Code AE — Communication Error
What this means
The AE error code indicates a communication failure between the main PCB and the sub-PCB inside the dryer. This is an internal electronics issue, often caused by power surges, loose connectors, or a failing control board.
Alternate codes: AC, AE4
Step-by-step fix
3 stepsPower cycle the dryer
Unplug the dryer for 5 minutes to allow the control boards to fully discharge, then plug back in and try a cycle.
Communication errors are sometimes caused by voltage spikes during storms.
Check the power supply
Ensure the dryer is plugged directly into a proper outlet — not an extension cord. For electric dryers, verify the 240V outlet is working correctly.
A loose prong in the dryer outlet is a common cause of intermittent power issues.
Inspect board connectors
If comfortable, remove the top panel and check that all ribbon cables and wire connectors on the main control board are firmly seated.
Ground yourself before touching circuit boards — static discharge can damage components.
When to call a professional
If a power cycle doesn't resolve this, a control board likely needs replacement. This requires professional diagnosis to determine which board is faulty.
