I need to replace my window operator but not sure of the correct part number needed. Please see pics. I was on the Swisco website and found possible replacement parts:
39-239B or 39-239C. These windows were installed in 2004
Please advise.

Thanks for the confirming the correct part number. I received the SS replacement window operator ( 39-239C) today. I removed the broken operator and replaced with the replacement with no problems. I was trying to remove the cover from the original operator, but looks like the cover is part of the operator thus unable to remove the original cover. How do you remove the operator cover from the operator? I could remove the handle with no problems.

It's likely that your old cover cannot be removed, as you surmised. For some older operators, the cover is permanently affixed to the base and cannot be removed in any way. That's why I suggested the 39-451, just in case.
