Tips On Removing A/C Roof Cover
My Rockwood trailer has a Dometic roof A/C unit, non-ducted. The unit is vibrating badly when running -- worse on med and high. I believe dirt daubers may have built a nest on the blower wheel, causing the fan wheel to be out of balance. Does anyone have any tips or things to watch out for when removing the A/C shroud so that I can access and clean the wheel ? Is it fairly easy to get to the screws and remove ? I plan to put plywood on the roof to get to the unit -- don't want to risk damaging the roof from walking on it.
Any other things that could be causing the bad vibration ? Are there any other holddown screws or bolts that should be tightened while I'm up there (or inside for that matter) ?
I do remember turning the A/C on in the past, and pieces of dirt and bugs have blown out. That's why I think the dirt daubers are the culprit. I also had to dig two big nests out of the hot water heat flue, so I know they are around the storage location.
