Went camping this weekend, was pretty cool out but the fan still cycled constantly. We bought a digital thermometer and put it in the fridge, and it was down to 29 degrees. turned the temp up, got that dialed in and pulled the fuse in the fan wire, and the temp still stayed just right. The real test won't be until next year when it is 95 degrees and see if it stays cool without the fan. Dometic wants 110 sq. inches of vent area, right now after opening things up I only have 51. The most I can get if I rebuild the cabinet above the refer is 108, still below the minimum required. The vent would allow 133, but because of the engineering of the coach 108 is max I can ever get. Very disappointing.
