We have a marquis epic 2007 I believe . we just had the motherboard changed last month, now jet 1 barely blows air compared to jet 2 which blows really strong. Even when on high. A dealer changed out the motherboard. What can be causing this, could it be the motor? Though we hear it working.( louder then the other one)
Also since then we notice more soot or white stuff at bottom by the filter/flow cages. There wasn’t any before then.
