Original wiring and controls
Farmers Branch homes cluster around a 1993 build year, which puts a lot of openers here well past the point where the logic board, the drive gear, or the safety reversal sensors were ever swapped out. If nobody's touched the unit since the house was framed, you're likely running on the original chain or belt drive, original wall control, and wiring that's brittle from three decades of Texas heat cycling through the attic space above the garage.
