The most common problems reported with residential garage door openers include misaligned or blocked safety reversing sensors (photo-eyes) that cause the door to reverse immediately or refuse to close, stripped internal nylon drive gears from lifting heavy unbalanced doors, snapping extension or torsion springs, intermittent remote control signal interference, and Wi-Fi network connectivity dropouts on smart models. Safety Warning: High-tension springs store lethal force; never adjust or repair springs without proper winding tools. Verification: Check sensor LED alignment indicators and test door balance manually using the red release rope.
