  • Small flathead screwdriver (optional)

  • Anti-static gloves (recommended but optional)

🔄 Step-by-Step Fuse Replacement

  1. Unplug the Miner
    Always disconnect power before opening or repairing any device.

  2. Locate the Fuse
    It’s usually positioned near the power input or within the inlet power socket. Check the side panel or rear inlet.

  3. Remove the Damaged Fuse
    Use your needle-nose pliers or tweezers to gently pull out the blown fuse.

  4. Insert the New Fuse
    Align the new fuse into the same holder. Make sure it’s snug and secure.
