UPDATE 4/11/17
Had to go out to the local Camping World to pick up a couple of those twist access panel locks. Checked and they had the circuit board for the refrigerator ($40.00 more than internet pricing). Since we are taking out in the morning I went ahead and purchased it.
Took about 5 minutes to swap out, labeling the wires before removing from old board. It's now working on gas and AC. Once again thanks for all the input and suggestions on what to check, especially to dougrainer for confirmation on the high humidity switch/check light connection.
