Garage Door Only Opens Halfway in Chattanooga

**Broken spring.** With a snapped torsion spring the opener can lift the door six to twelve inches before the motor's torque can't overcome the door's full weight (150–250 lbs). It stalls, reverses, and won't try again. Look for a 2–4 inch gap in the spring above the door.

**Up-travel limit set too short.** If the opener thinks the door has reached the top before it actually has, it stops. Re-programming the limit takes minutes.

**Force setting too low.** Cold weather stiffens lubricant on rollers and hinges; if the opener's force is borderline, the first cold morning is when the door starts stopping halfway.

**Stripped main gear.** A worn or stripped drive gear in LiftMaster, Chamberlain, and Genie openers slips under load and the door stops partway. We carry the right gear kit on every truck.

**Track obstruction or bent roller.** A flat roller or pinched track stops the door at the same point every time.

Our technician will manually disconnect the opener with the red release cord, check spring balance, inspect every roller and hinge, test all limits, and verify motor force—then quote a flat-rate fix before any work begins. Most halfway-stop repairs are completed in 60–90 minutes on-site.
