    Bedroom AC Vibration

    2015 350 M. Just got unit and it seems the bedroom AC sure does vibrate a lot. Is this normal or common on the 350's?

    Three things to check right off the bat....

    Is the "air dump" open or closed? When closed they will vibrate more.

    Take off interior cover (4 screws - if Dometic) and verify that the ducting is not partially or fully taped over. It maybe the air has no where to go.

    While cover is off check the mounting bolts. They should be snug, not super tight.

    While cover is off check for mud-dobber wasp nest on fan blades, the weight of the nest will cause an in-balance and can cause motor bearings to fail. one shady mechanic told me he could make 150.00 for re-balance the blower when he was just removing the nest. he knows most people will not climb up and watch what is being done.

    Found the culprit. The shaft on the fan motor is bent, therefore the bad vibration. I'll be calling support to see if we can get it replaced under warranty.
