ApplianceDryer
Quick answer
AC6 and AE6 mean the main and inverter boards are not communicating.
Model compatibility: Samsung reuses codes across series and model years, so AC6 / AE6 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
AC6 (or AE6) is a communication fault between the main and inverter circuit boards.
Samsung’s tumble dryer list reads AC6 and AE6 as “check the communications between the main and the inverter” circuit boards. The entry has no model limit.
What to do
Try restarting the cycle. Should the code remain, contact a service centre.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
