We own a 2016 21C and the last time camping we had trouble getting the propane to light. It did finally catch after maybe 5-10 minutes. I am now a bit paranoid that it will fail to light on our next trip coming up in early August. I want to check the burner and igniter to be sure they are clean and the gap between the igniter and burner is what it should be. I watched a YouTube video that was very helpful except when I went to attempt the disassembly, there seems to be a rectangular, white plastic "cup" for lack of a better word, that is directly above the screw I need to remove to access the aforementioned parts. Does anyone have experience in how this "cup" can be removed so I can access the burner? A quick look did not show how this is held in place, and there isn't enough room to put a driver bit on top of the screw and turn it with a small wrench.
