Introduction

The Ubiquiti Unifi Dream Machine (UDM) is a powerful all-in-one networking device that combines a router, switch, access point, and security gateway into a sleek, compact unit. While Ubiquiti is widely used and recommended by IT Professionals, like any electronic device, the UDM isn’t immune to failure.

In this teardown, I'll be looking inside the UDM, identifying key components, potential failure points, and walking you through step-by-step disassembly with detailed photos and insights.

⚠️ Warning: Disassembling your UDM will void any remaining warranty, so proceed with caution. If your device is still under warranty, check with Ubiquiti Support before attempting any repairs.

    • This is the hard part, be patient

    • The power supply pin clip and RF grounding wire are keeping the shell connected to the core

    • Using a spudger or pick, gently pry off the RF grounding wire tape.

    • Once the RF grounding wire tape is removed, slowly twist and pull to release the power supply pin clip

    • In my case, the power was making it to the board, but wasn't being to converted from AC input to DC output

    • You can see in the red circle that likely there appears to be some discoloration. My guess, with this tight design, it overheated
