Sorry, yet another post but thought others might find this useful...
Talking to a Dometic customer service rep... They said there is a fix for the cycling fan issue. She said a service center will need to relocate the temp sensor controlling the fan and this will stop the short cycling. I tried to ask if this is something easy I could do but she didn't know the details. I just got a service center in my area's phone number. I called them and they never heard of the issue. They said they would also need to call Dometic so they could find out how to fix the problem. He suggested I try to call back and see if I could get someone in tech support. I asked the rep if I need to have the fan for normal operation. She said yes but I don't know if that's true or not. If ventilation is properly designed the fan only helps from what I know and isn't required. Ideally I'd like to just move it myself (if it's easy) because dragging the camper into a service center for just this is more a pain in the butt.
