Yep, small window on the kitchen side (17.56-1), one of the struts is stuck open, had to unscrew it, the other one is hit and miss re opening. Both are on the list of things to fix under warranty.
I think replacing them will not solve the problem as they appear to be poorly designed - too small for starters and the entire thing seems to be made of plastic (even the strut rod from memory). The outer housing seems to shrink (as plastic does) on hot days affecting the movement of the inner rod and bearing is my guess. Unlike metal, once plastic shrinks it doesn't come back to shape easily when cool.
When I get the replacement, I think I'll try
@skippy suggestions and pump some silcon grease in on all of them to help with lubrication and possibly the heat.
