Abstract
A movable barrier that is at least partially counterbalanced by a spring is moved from a first position to a second position while substantially simultaneously monitoring at least one characteristic associated with moving the movable barrier to provide at least one monitored characteristic. The at least one monitored characteristic is compared to a predetermined criterion. When the at least one monitored characteristic does not meet the predetermined criterion, an alarm condition is set to indicate a failure of the spring.
