Thanks!
Hello,
It does sound like you may need a new operator assembly, though you should check the hinges and other internal window linkage for wear and damage. Take a look at the video below that will help you determine the correct Encore operators for your windows. Thanks for posting!
We do not have an installation video for these particular operators but we do have a general casement window operator tutorial here, which shows a similar trim piece covering the base. In our experience, removing the trim is the trickiest part since the operator simply unscrews at the base and the arms would be released from the track and bracket mounted to the sash. Thank you.
