A gate that has lost speed or stops mid-cycle is warning you before it fails outright. Here is what it means.
Gates do not usually die all at once. They get slow, they hesitate, they stop three feet short and reverse. Those are early symptoms, and fixing them now is far cheaper than the emergency call when the gate finally quits.
Here is what causes each behavior.
Jerking usually points to a worn gear, a chain with a bad link, a slide wheel with a flat spot, or a motor with a failing winding. On swing gates, a worn arm pivot or a bent arm shows up as a shudder at the start of travel.
The wrong fix for a gate that stops halfway is to turn up the force until it pushes through. That is how gates injure people and how motors burn out. We find the bind, fix the hinge or track, and leave the safety settings where they belong.
On a DC operator, almost always the battery or charger. On an AC operator, dragging hardware or a worn motor. We test both on the service call.
There is a bind at that point: a hinge, a track, or the driveway itself. The operator is reversing to protect whatever it hit.
You can, but you should not. It defeats the obstruction safety and stresses the motor. Fix the drag instead.
Typically two to four years in Houston heat. A battery that is slow to recover after cycling is near the end.
The diagnosis is. Batteries, hinge adjustments, and track cleaning are usually done the same visit, quoted in writing first.
Call and we answer within 30 minutes. The owner or a senior technician comes out, diagnoses, and gives you a written quote before any work starts.
