Actuator

Hello there. Yes, when that worm gear pops out with the handle, it means the entire operator must be replaced. Can you show us the mechanism from a bird's eye view with either the operator removed from the window or the window open, so I can clearly see the arm(s) that move the sash? That will narrow it down.

Perfect, thanks. Looks like you might have an older version of the 39-036. Its opposite-handed version is the 39-035. Please compare. For covers and handles, see the 39-114L and 39-107.
