Thanks for the replies so far. I appreciate it.

I've done a little more playing, so if it helps, please let me know.

When I set the fan to low, it started and runs. Then I turn it to A/C and or started and the trailer cools down.

When it gets cool, the fan and the A/C shuts off. To get it to restart, I have to set it to fan and wait for the fan to start, then I can set it to A/C. If I don't wait for the fan to start, the A/C won't restart.

Does this point to one or the other?
