PS4 controller repair
These pads are old enough that a high resting radius is ordinary wear.
What to check first
Identify 05C4 versus 09CC on the DualShock 4 page so you order the right board if you are repairing. A missing button in the tester is a switch or a ribbon. A smooth trigger that tops out early is the potentiometer, not the plastic trigger.
- Warranty is unlikely on a 2013–2016 pad.
- Do not soak the board to “fix” drift.
- Retest every replaced part before you close the shell.
Confirm the reading on the live tester before you buy parts or change firmware. The number on that page is what your browser actually receives.
A practical next step
Repeat the same test after each change and write the resting radius down. A fix that does not move that number did not fix the sensor. If the offset stays above about 0.12 with your hands off the sticks, plan a module replacement rather than another software pass. Model notes live in the controller library.
Frequently asked questions
Does this page change my controller?
No. GamepadTesters only reads the Gamepad API in your browser. Calibration writes, firmware updates, and stick swaps happen in the maker’s tool or at a repair bench.
