How to Reset Sonos Arc: Factory Reset Guide + What to Try First

If you’re searching for how to reset Sonos Arc , first determine whether you actually need a factory reset. A factory reset completely erases the Arc’s saved settings and removes it from your Sonos system, so Sonos does not recommend using it as a routine troubleshooting step.

If you’re selling the soundbar, giving it away, starting from scratch, or Sonos Support has specifically advised a reset, the steps below show how to factory reset the Sonos Arc using the rear Join button. If you only need to change Wi-Fi or fix a temporary connection issue, you can usually do that without resetting the Arc.

Quick Answer: How to Reset Sonos Arc

To factory reset a Sonos Arc, unplug the power cable, hold the Join button, reconnect power while continuing to hold the button, and wait for the light to flash orange and white. When the light flashes green, the reset is complete and the Arc is ready to set up again.

Before You Factory Reset Your Sonos Arc

Important: A factory reset erases the Sonos Arc’s saved settings and removes it from your Sonos system. Sonos does not recommend factory resetting as a routine troubleshooting step. If you are only changing Wi-Fi, fixing a temporary connection problem, or restarting the soundbar, try the Sonos app or a normal reboot first.

Use a factory reset when:

• You are selling or giving away the Arc.
• You want to completely erase its configuration.
• Sonos Support specifically instructs you to reset it.
• You genuinely need to add it again as a fresh product.

Conclusion

A Sonos Arc factory reset is useful when you need to completely erase the soundbar, sell or give it away, or start fresh after specific troubleshooting guidance. For ordinary Wi-Fi, app, or playback problems, a reboot or network update is usually the better first step. If you do need a factory reset, hold the Join button while reconnecting power and wait until the status light flashes green before setting the Arc up again.
