What 1 AC7 means

On Samsung dryers, 1 AC7 is listed as an Electronic Control Error. It means the dryer's main control has reported a problem with its own electronics, and the cycle stops. Because the code applies across the line, we describe it by product type: Samsung dryers that show a code on the display. You will see 1 AC7 on the screen, and the dryer will not start or will stop mid-cycle.

Common causes of 1 AC7

  • The main control board reporting an internal problem
  • A connection between the control and the panel that has loosened
  • A power interruption that left the control in an error state
✓ One safe check you can try

1. Press Power to turn the dryer off. 2. Unplug it or switch off its breaker for 2 to 3 minutes. 3. Plug it back in or turn the breaker on. 4. Start a cycle again. 5. If 1 AC7 shows again, stop using the dryer.

! Why to stop there
  • Restarting the dryer cannot tell us whether the control itself has a problem or only had a one-time upset.
  • We test the power coming into the dryer and the connections between the control and the panel before we judge the board.
  • You will see a written price before work starts, and the repair has a 30-day workmanship warranty.
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

1 AC71 AC7 questions
What does 1 AC7 mean on a Samsung dryer?

It is an Electronic Control Error. The dryer's main control found a problem within its own electronics and stopped the cycle, so the dryer will not run until the condition is cleared.

Will unplugging the dryer clear 1 AC7?

Powering off for 2 to 3 minutes and restarting is the standard first step. If the code returns right away or on later cycles, the control needs to be tested.

Is it dangerous to use the dryer with this code?

The dryer usually will not run with the code showing, and we do not recommend forcing it. Leave it unplugged until we have tested the power and the control.
