Short answer: Your garage door is the single largest moving object in most homes, and its safety features quietly drift out of adjustment over hundreds of open-and-close cycles. Spending five minutes once a month on two simple tests catches those problems before they become an injury or a surprise breakdown — no tools required.

The Auto-Reverse Test That Protects Kids and Pets
Every opener made since 1993 is required to reverse the door if something is in the way, and it does this two different ways — so test both. First, the contact reversal: lay a flat board, like a scrap two-by-four, on the floor directly under the center of the door, then press the button to close. The moment the bottom of the door touches the board it should stop and reverse back up; if it keeps pushing down or hesitates, the down-force is set too aggressively. Second, the photo-eye test: those two small sensors bolted about six inches off the ground on each side project an invisible beam across the opening. Start the door closing and wave your foot or a broom through that beam. The door should immediately reverse. If it doesn't, the eyes are misaligned, dirty, or failing — a repair worth making the same week.
The Balance Test That Predicts Spring Failure
This one tells you how much life is left in your springs, which is the part that fails most dramatically. With the door closed, pull the manual release cord to disconnect the opener, then lift the door by hand to about waist or chest height and let go. A properly balanced door will hover right where you left it, held by spring tension alone. If it sinks and slams shut, the springs are weakening and losing their counterbalance; if it flies upward out of your hands, they're overwound. Either way the opener is now compensating for that imbalance every single cycle, wearing itself out faster. A door that no longer holds its position is often weeks-to-months from a broken spring, so a balance that's clearly off is your early warning to schedule service before you're stranded.
What a Failed Test Is Actually Telling You
Treat a failed test as information, not a to-do you can shrug off. Photo eyes that won't reverse the door defeat the exact feature meant to protect a child or a pet in the doorway, and in Sacramento's dusty valley air the lenses genuinely do haze over and lose alignment when a car bumps the bracket. A failed contact-reversal usually means the opener's force settings need adjustment — sometimes a homeowner dial, sometimes a technician's job depending on the model. And a failed balance test points at the springs and their tension, which is high-stakes hardware you should not attempt to adjust yourself; the winding bars and torque involved put this squarely in professional territory. Logging the date of each monthly test also gives you and any technician a clear timeline of how quickly things are changing.
