Error codeAC7, 1 AC7
ApplianceDryer
Samsung’s US list uses 1 AC7 as its sample “Electronic Control Error”, and AC7 is the same entry. It sits with the codes outside the main groups, which generally concern the dryer’s sensors and components. The entry is not limited to particular models.
What Samsung asks owners to do
Leave the dryer off for 2-3 minutes.
Power it on and restart the cycle.
If the error persists, the user manual has the exact troubleshooting steps for your model.
When the error comes back, request service.
Do not confuse it with
AC6, AE6: the link between the main and inverter boards.
AC: internal components that are not communicating.
Still seeing AC7 after the power cycle? Samsung dryer repair is on offer for the San Francisco Bay Area; call (415) 969-6153 and report the code, the model number and the two or three minutes off that you already tried.
Model compatibility: Samsung reuses codes across series and model years, so AC7, 1 AC7 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
