Quick Answer

If your garage door travels all the way down, touches the floor, and then immediately reverses back to the open position, the problem is almost always related to the travel limit settings or the close-force adjustment on your opener. This is different from a door that reverses mid-travel (which is usually a sensor issue).

The Door Closes Then Bounces Right Back Up

Cause 1: Close Travel Limit Set Too Far

Every garage door opener has a close-limit setting that tells the motor where the “fully closed” position is. If this limit is set even slightly too far — meaning the opener tries to push the door past the floor — the door hits the ground, the motor senses resistance, and the safety reverse kicks in. The fix is to reduce the close-limit travel by 1–2 increments on your opener.

On LiftMaster openers, locate the travel adjustment screws or buttons on the side of the motor unit. The “down” or “close” adjustment controls how far the door travels. Turn the screw counterclockwise (or press the down-arrow button) in small increments — 1/4 turn at a time — and test after each adjustment.

Cause 2: Close Force Set Too Low

The close-force setting controls how much resistance the motor will push through before reversing. If the force is set too low, the weight of the door pressing against the floor seal creates enough resistance to trigger a reversal. Increase the close-force setting by small increments. On LiftMaster models, this is a separate adjustment screw or button labeled “Force” — turn it clockwise or press the up-arrow in small increments.

Cause 3: Worn or Swollen Bottom Seal

In Tucson, summer heat causes rubber bottom seals to expand. If your seal has become thick, warped, or is curling under the door, it creates extra resistance when the door closes. Inspect the seal — if it is cracked, hardened, or deformed, replace it. A new rubber or vinyl bottom seal costs $2,000 – $2,800 and takes about 15 minutes to install.

Cause 4: Binding in the Tracks

If the tracks are slightly misaligned, bent, or clogged with debris, the door encounters resistance at the bottom of its travel. Check for dents or bends in the tracks, especially near the floor. Clean dust and debris from the bottom of the tracks. Lubricate rollers and hinges. If the tracks are visibly bent, do not attempt to straighten them yourself — call a professional to avoid damaging the door.

Cause 5: Broken or Weak Torsion Spring

If one of your torsion springs has broken or lost tension, the door becomes heavier on one side. The opener may be able to push it down, but the uneven weight triggers the safety reverse at the bottom. Check the springs above the door — a broken spring will have a visible gap in the coils. If a spring is broken, do not operate the door. Call a professional for replacement.

Safety Note

The auto-reverse feature is a critical safety mechanism required by federal law (UL 325). It prevents the door from crushing objects, pets, or people. Never disable or override the auto-reverse function. If adjusting the travel limits and force does not solve the problem, there is an underlying mechanical issue that needs professional attention.
