No way I am spending 400 bones for them to enlarge the hole in the roof, if that is the issue I will do it myself. I sent an email to Eclipse and my contact there who has helped me several times said she would forward it to and engineer and they would get back to me. The way I see it I can either cut the hole bigger (a few hours work) or take the fridge out to check the thermistor myself (also a couple hours). Depends on what Eclipse says, but my guess is they use the same template for every trailer with that size refer, so I really doubt that is the problem. The other odd thing is the fact that no matter what the temp outside it cycles every 28 seconds like clockwork. The other thing is that my buddies have NEVER heard their fans turn on - EVER - and their rigs are the same age as mine.
