did some digging
Sorry I took so long to get back.
I called Atwood to verify what was going on.
According to their tech support the roof air I have does not cycle the fan.
Told that the compressor would cycle,which it does, but the fan runs continuously unless power is removed,turned off.
I asked if it would matter if it stayed on for 2 weeks straight and was told that is the way it was designed.
The only good thing about it running,though this is quieter than the others,I don't have to keep readjusting the tv volume.
Thanks for everyone's help.
