Quick Answer
An Opener Has No Single Expiry Date
A garage door opener can remain useful for years when it is correctly matched to a balanced door, operates without recurring faults and still supports safe automatic travel. Another unit of similar age may need replacement sooner because of heavy use, unavailable components, repeated electrical problems or failed safety functions.
Age is helpful context, but it should not be the only reason to keep or replace an opener. The stronger decision comes from the unit’s present condition, the garage door it is moving and whether the system can be tested and repaired with compatible parts.
