Where This Job Goes Sideways
Melissa's housing stock is young. The median home here was built around 2015, and most of the subdivisions going up around it since the early 2000s share the same builder-grade double garage: a wide steel sectional door on a belt-drive or screw-drive opener installed when the house was framed. That opener is roughly ten to fifteen years old now, which in opener years is right at the point where the plastic drive gear inside the housing starts to strip, or the logic board that reads your remote's rolling code starts to fail. This is a different failure pattern than you'd see on 1970s or 80s stock. Nobody in Melissa is dealing with a worn-out screw-drive from the Carter administration. What we see instead is a door that still looks new, hardware that still looks new, and an opener quietly reaching the end of the run its original circuit board was built for. The mistake homeowners make is assuming a dead opener means a dead door. Most of the time the door itself, being a decade newer than the opener logic, is fine. It's the board or the gear that gave out.
How We Fix It
We come out from Prosper, about 15 miles, so we diagnose on the first visit rather than sending someone to look and someone else to fix. First we separate mechanical from electrical: does the motor run but the door not move, or does nothing happen at all. A running motor with a stuck door usually means a stripped gear or slipped belt, both quick swaps. A silent unit points to the board, the wall switch, or the power feed to the unit itself, and we test each in that order rather than replacing the most expensive part first. If the reversing sensors are out of alignment, which happens more than people expect on garages that get bumped by bikes and lawn equipment, we re-aim and test the reverse before we call the job done, since a misaligned sensor is a safety issue, not just an annoyance.
What You Are Seeing
The opener runs but the door doesn't budge, or moves an inch and stops - usually a stripped gear or worn belt on a unit from the original build. The door reverses the second it touches the floor - sensor alignment, common on garages with kids' bikes or storage bins near the track. The remote works from the driveway but not the car in the garage, or works one day and not the next - often a circuit board losing its hold on the rolling code, which gets worse with age, not better. Grinding or a burning smell from the motor housing - a gear or motor bearing giving out, and worth shutting the opener off and using the manual release until we look at it, since running it further can turn a gear swap into a full motor replacement.
