Thanks JRTJH.
It's possible I'm trouble shooting a problem I don't really have? We are at the Outer Banks, NC and the last few days have been in the 90's with high humidity. So maybe I'm expecting too much from it?
I must also admit to sometimes "grazing" as you put it.
I have a couple extra fans installed in the back and have been running them, but the weather's been very uncomfortable outside.
I did unplug my thermister and it ohm'd out at 743k ohms. I left it unplugged for now. I have 5 temp settings on the eyebrow panel. I guess they do nothing if the thermister is unplugged? Is that correct?
I think this board may have been replaced at one time. It shows a date 10215 on the back, (that's how it's written.) I assume that's 2015 something. The trailer is 2011.
Thanks for the help. I'm on another learning curve.
