    Central Vacuum not working

    Just bought a barely used 2017 Class M350 TH and the central vacuum is not turning on. We removed the cover and the bag was not attached, we cleaned it out, put bag on correctly, turned the switch to on and nothing happens with the kick plate vacuum or when we hook up the hose. Fuses are fine, could the motor be burned out? Do most people leave it "on" while camping for convenience or turn it on just when they are going to use it? The manual is no help

    Have you checked to make sure its plugged in? If you remove the false wall in basement, you should have access to the outlet where its plugged in.

    Do you have an inverter?
    I too had this issue. It seems that GD wired it so that the inverter needs to be "on" for the vacuum to work.

    Even when plugged in to shore power? Our runs on shore or inverter.

    I had to go check, as we never camp with in campgrounds with hookups (I originally though the vacuum as 12V) the aswer is... Yes it works on shore power.
