Assuming you have HWH jacks on your Winnebago product and assuming they have not changed since I had one, you may be able to stop this from happening by not shutting the system off at the panel after raising the jacks. Let them time out on their own. Dont know why this works but it was what I was told and it worked for me at the time.

Hydraulic fluid expands as it gets warm. This will move the jacks just enough to turn the warning on. After I started letting the system "time out" I had no more problems.(Winne with HWH jacks)
