Of Macbook Trackpad Replacement Happens Because Of these
Unresponsive Click/Taps
Trackpad fails to register clicks/taps, making navigation impossible. You may find that no matter how much you swipe or tap, nothing happens on the screen.
Erratic Cursor Movement
Sometimes, the trackpad works fine, but the cursor moves erratically across the screen. This can make it difficult to select items or use your MacBook efficiently. The Cursor jumps unpredictably can be due to dirt, liquid damage, or faulty sensors
Physical Damage
Internal/external cracks on your Macbook Trackpad that appear spontaneously, often denied warranty coverage. Crack on trackpad can be due to swollen battery, if not then due to exterior force that causes the surface layer of the trackpad to crack. This can affect the sensitivity of the trackpad to be greatly reduced.
Liquid Damage
Spilling liquid on your trackpad can cause unresponsiveness or corrosion (e.g., coffee, tea). The trackpad is made up of coil (that produces haptic feedback) and also electronic chips. Once liquid has hit the trackpad (whether the coil or the electronic chips), your trackpad will tend to malfunction.
Software Glitches
macOS bugs or misconfigured settings (e.g., Force Click issues) can cause your trackpad to be unresponsive to clicks or it can also behave erratically.
Click Mechanism Failure
Trackpad stuck in "clicked" state due to debris or hardware wear. As mentioned above, The trackpad is also made of coil, which transmits electric signal and convert into motion signal, which gives us the clicking feedback. If the trackpad coil has failed, it fails to transmit electric signal, which does not give us the so called "haptic feedback" and we deem it as faulty trackpad.
