Steam Deck Left Thumbstick Replacement
Use this guide to replace the left thumbstick on your Steam Deck LCD. The stick is part of a complete module and needs to be replaced as one unit. Although nearly identical, the procedure for the right thumbstick can be found here.
Remember: follow general electrostatic discharge (ESD) safety procedures while repairing your device.
Replacement thumbsticks require calibration to work as expected. Read about how to do that here.
Note: Each Steam Deck ships with one of two different models of thumbsticks, Type A or Type B. Although nearly identical, capacitive touch capability relies on the correct type to be installed. To identify which replacement thumbsticks you need, navigate to Settings → System and check the Steam Deck Controller ID: if the Controller ID starts with “MEDA” that device uses Type A thumbsticks; if the Controller ID starts with “MHDA” that device uses Type B thumbsticks.
