This is what happened after about a minute of the new sound file...
No sound, no movement. It would move in conventional only, but the fan would still pulse. So I opened her up and started with pulling the connector for the fans, also to no avail.
Then I went deeper... and now it’s truly dead. Only thing I get is track power to the lights. All the lights, at the same time.
So... I’ve called in a professional.
