# Samsung dryer error code AC

### What AC means on this make

The panel and the main board have lost contact with each other. Connections are the first and cheapest suspect, particularly in a machine that has been moved or stacked, and a full power cycle clears a genuine share of them.

### The other ways Samsung prints this one

AC · Et · AE · EEE · AE4 · AE3 · AE5 · E3 · 1 AC

Samsung publishes a condition and then every string that can stand for it, and which one your machine shows depends on the panel it was built with. They mean the same thing and they are one page here, so whichever of them you searched for, this is the right page.

### Where this appears, and why not to clear it

On the appliance’s own display. Samsung reports errors two ways: machines with a digital display show a code, and the same machines without one blink their cycle lights instead. Both are published by the maker and both are on this site. Photograph what the panel shows before cutting the power — Samsung asks for this itself on its refrigerator and dishwasher pages, and it is the one thing that makes a first visit more useful. A code that has been reset is information a technician no longer has.

### What to do about it

- Switch the dryer off at the breaker for a minute and back on.
- If the pair has recently been stacked, moved or had a kit fitted, say so — that is when this appears.
- If it returns, the harness between the boards is what gets checked before either board.

### Where this goes next

The job this usually becomes is [appliance control board repair](/services/appliance-control-board-repair/), and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call [(305) 506-1256](tel:+13055061256) and describe what the panel is doing before booking anything.
