Manual Balance Test Procedures
The Balance Test
The manual balance test is the most important final check on every garage door installation. It verifies that the spring system correctly counterbalances the door weight. A properly balanced door should stay in place at any position when released.
Interpreting Results
Properly Balanced
Door stays in place or moves less than 1 foot from release point
Door feels light and easy to lift
Door moves smoothly without jerking
Door Rises (Spring Too Tight)
Door moves upward after release
Spring has too many turns or too high IPPT
Action: Remove 1/4 to 1/2 turn from spring
Door Falls (Spring Too Weak)
Door drops downward after release
Spring has too few turns or too low IPPT
Action: Add 1/4 to 1/2 turn to spring
The manual balance test requires disconnecting the opener and releasing the door at 3-4 feet height - a properly balanced door stays within 1 foot of the release point. If it rises, the spring is too tight; if it falls, the spring is too weak.
