If I'm not mistaken, the 12 volt air compressor is only for the toilet and the air doors. Before you try adjusting the individual door mechanisms, you should check the pressure regulator at the 12 volt compressor. Both of my air doors were "slamming" too. When I checked the regulator it was "pegged" well over 60 lbs.! I simply adjusted it down to the max.
60 lbs setting..... it made a huge difference. Toilet works fine at this setting too. Guys, please correct me if I'm wrong of this. This is the first time I felt I've had some useful knowledge to contribute. Best Regards, Jerry
