You should replace your residential garage door opener when it reaches the end of its normal operational lifespan of 10 to 15 years, or earlier if it exhibits chronic mechanical failures, such as a motor that hums loudly without turning the drive sprocket, stripped internal gears that slip continuously, persistent electronic logic board crashes, or a complete lack of modern safety reversing sensor compatibility. Upgrading also introduces modern smartphone app connectivity. Verification: Disengage the manual release and test the door by hand to ensure mechanical balance before blaming the motor.
