DJI Mini 3 Power Button Replacement – Drone Motherboard Switch Repair
The power button on the DJI Mini 3 is a small but essential component that controls the entire startup and shutdown process of the drone. Over time, this switch can fail due to wear, impact damage, moisture, or internal board issues. A faulty power button often leaves the drone unable to turn on, unresponsive, or stuck during startup.
Replacing the DJI Mini 3 power button restores normal functionality, allowing you to reliably power the drone on and off. This repair is much more cost-effective than replacing the entire motherboard and is one of the most common small-part fixes performed after heavy use or crash damage.
Common Signs of a Bad Power Button:
-
Drone does not turn on even with a fully charged battery
-
Button feels stuck, loose, or unresponsive
-
Power light does not activate
-
Drone only powers on intermittently
-
Requires excessive pressure to turn on/off

Why Replace the Power Button?
Without a working power switch, the Mini 3 cannot function at all. Replacing just the button is an affordable solution compared to swapping the entire mainboard. This repair is recommended if your drone still shows signs of life (battery lights, charging, or connectivity) but won’t respond to the button press.
Installation Notes:
The power button is soldered directly to the mainboard. Replacement requires micro soldering skills, precision tools, and steady hands. It is best performed by experienced drone repair technicians or hobbyists skilled in PCB work.
Once replaced, your DJI Mini 3 regains full on/off control and reliable startup, extending the life of the drone and saving money on costly board replacements.
