Hope the pics work. This is a RTU that I went out to a few weeks ago with another tech. He said he was having rollout switch issues whenever it got windy. I pointed out the exhaust. He said he thought that was problem too but didn't know what to do. I had to go back about a week later same thing reset rollout. Called other tech and suggested to extend exhaust, I know it's probably not the best thing to reinvent things but what els can you do sometimes. I also suggested inspecting behind collector box to make sure HX wasn't plugged, he said he already checked HX. So today I had to go back again I decided to try the exhaust extension. I'm not happy with it but what can I do. The thing I don't get is it looked like they went through great length to jam the thing in there why the heck would they not have taken something so obvious into consideration. Guess you can't fix stupid.
