I'm with Wayne,
Just take the screws off the side, open it up and visually check and see if anything came lose. The colors on the ends of the connections are color coded to match each other, just look to see if any of the white plugs are not connected.
IF in doubt, don't mess with it, could be something simple.
Unfortunately, that's why we say do the test run during the week so you can call CS in case of questions.
Sorry it happened, I've not heard of this issue so not sure what's the alarm is for, so let us know what they say.
They'll help you out.
p.s. I could try you were trying to find out, found 4 or 5 posts with the same problem. Just post the FE owner questions in the FE owner forum and most of us will see it anyway
