Why won't my garage door stay open on its own?

Springs Hold the Door Up, Not the Opener

It surprises a lot of homeowners: the opener contributes almost none of the lifting. Its motor is sized to guide a door that the springs have already made nearly weightless. When a door creeps down from the open position, or will not stay put when operated by hand, the counterbalance math has failed. Springs lose tension three ways: gradual fatigue over thousands of cycles, a full break (you would usually hear the bang), or an original installation that used springs slightly too light for the door, which is more common than it should be on builder-grade doors in newer additions around Mustang and Piedmont.

Heat cycles matter too. Oklahoma doors go from 20-degree January mornings to 110-degree attic-adjacent summers, and that expansion-contraction cycling fatigues spring steel faster than the 10,000-cycle rating suggests. A spring that is eight or ten years old here has usually earned its retirement.

The One-Minute Balance Test

You can confirm weak springs yourself safely:

• Close the door fully, then pull the red release cord to disconnect the opener.
• Lift the door by hand to waist height and let go carefully, keeping hands ready.
• A balanced door hovers or drifts an inch or two. A door that sinks steadily has weak springs. A door that drops fast has dangerously little tension left; reconnect the opener and stop testing.
• Repeat at the fully open position. A healthy door stays parked; a tired one starts sliding down.

If the door will not stay open by hand, the opener has been quietly straining against that imbalance every cycle, which is why weak springs so often take an opener's drive gear with them. If your opener has been grinding or struggling, our answer on grinding noises during opening explains that connection.

Adjustment vs. Replacement, and What It Costs

Torsion springs can sometimes be re-tensioned a quarter or half turn if they are young and simply settled, but winding springs requires proper bars and experience; a slipped winding cone can break an arm. Do not attempt it with screwdrivers. If the springs are older, stretched, or wrong-sized for the door, replacement is the honest recommendation, and we quote it upfront with a free estimate. In the OKC market, the price of torsion spring replacement depends on spring size and whether you do one or the matched pair. We install high-cycle springs on request for homeowners who cycle the door six or more times a day.

One more reason not to wait: a door that will not stay open is a door that can come down on a bumper, a bicycle, or a person. If yours is sinking today, book online or call, and a truck stocked with spring sizes for CHI, DoorLink, Haas, Mid-America, and every other common door reaches most metro addresses in 20 to 50 minutes.
