Is the large filter in the bay for both the mid and aft units? Also, how do we gain access to the filter for the front unit mounted behind the bumper?
The more I learn - the more I realize how little I know!
I am intrigued as to what is going on that only 2 Cruisair units will operate. This is NOT an electrical system interlock in any way, at least by the original design per Vantare. You do have the SW4024 inverters (qty of 2) in your coach, correct? If this is the case, all the power for each leg runs through the inverters and there is no unloading to prevent ALL the loads on each leg from operating...UNLESS someone has added some interlock to prevent from overloading the inverters when shore or gen are not present ac sources.
When you say not more than 2 will operate, what is the remaining unit's status? Does the SMX control panel light up at all? How do you get the one that doesn't work to work? Do you have to turn off the breaker for the other unit on the same ac leg, or do you just turn it off on the control panel?
Thanks for the feedback.
Sincerely,
