Troubleshooting LiftMaster 4-3 Error Code

Encountering the LiftMaster 4-3 error code can be frustrating, especially when you’re in a hurry to get things done. When this error pops up on your LiftMaster device, it usually indicates a safety sensor issue. These sensors are crucial for ensuring the safe operation of your garage door.

One of the first things I do when facing the 4-3 error is to check if anything is blocking the sensors. Sometimes, a simple obstruction like dirt, leaves, or even a spider web can trigger the error. Clearing out any debris and ensuring that the sensors are clean might just do the trick.
