Joe, are you sure the fan is running and the compressor off? I'm having the opposite problem. The fan is cycling off/on but the compressor continues to run. The fan will run for maybe 30 seconds and then shut off for 2 or 3 seconds and then run for 30 seconds again. Repeat. Repeat. And then eventually, both shut off. I think I have good air flow and the trailer is staying cool.
