A properly balanced garage door moves smoothly and remains near halfway open when tested as the manual directs, instead of rapidly rising or falling. You can safely test balance on a closed door with the opener disconnected, but fixing an unbalanced door means adjusting spring tension, which is a technician's job, not a homeowner's.
How to Test Balance Safely
Only do this with the door fully closed and the springs and cables looking intact. If the door is already open, off its track, or a spring or cable looks broken or loose, skip the test and call for service instead.
- With the door closed, pull the emergency release cord to disconnect the opener.
- Use the lift handle to raise the door slowly toward halfway, staying out of its path and away from panel joints. Stop immediately if it feels heavy, binds or moves unevenly.
- If lifting is easy and even, carefully ease your support while keeping control of the lift handle and staying clear of the path. The door should remain near halfway. If it starts moving on its own, lower it only if you can do so without strain; otherwise move clear and call for service.
- Lower a smooth, controllable door fully. Follow your opener manual's release-reset and reconnection steps; cord direction is not the same on every model. Do not reconnect and operate a door that failed the test.
Why You Shouldn't Adjust the Springs Yourself
An unbalanced door almost always means the spring tension needs adjusting, and the method depends on whether the door has torsion or extension springs. A bar or spring that slips under tension can cause a serious injury. We rebalance the door by resetting spring tension to match its weight, then retest before we leave.
Signs Your Door Is Unbalanced
- It feels heavy or uneven when lifted by hand.
- It doesn't stay in place partway open.
- One side hangs lower than the other.
- The opener strains, runs hot, or wears out faster than expected.
When to Call
Call for service if the balance test shows the door drifting, if a spring or cable looks damaged, or if you'd rather not test it yourself. Leaving a door unbalanced puts extra strain on the opener and can lead to a cable or spring failing next.
FAQ
How often should I check garage door balance?
Once or twice a year is reasonable for most households, or any time the door starts feeling heavier or behaving differently.
Can I balance my garage door myself?
You can safely test balance, but fixing an imbalance means adjusting spring tension, which we don't recommend doing yourself due to the tension involved.
What if my door still won't balance after a service visit?
That's unusual. It can point to a bigger issue like the wrong spring size for the door's weight or damaged hardware, worth a follow-up call.
