My new large BGE has arrived but I'm finding the vent sliding screen and "door" very difficult to move. It appears that both can be slid too far open and then the screen prevents the solid door from sliding closed. Even when not opened too far both the screen and door are very difficult to move. We hit them with some WD-40 but should we be concerned this is not a good solution for something that will be near burning coals?
Any suggestions for making the screen and vent door slide more easily?
Wil they loosen over time?
