If it is like mine the steps are as follows.
Contact dinosaur boards (add www. .com and remove space) find out model number of replacement control board
Contact American RV in California and order same
Wait a few days for UPS man
Open outside compartment, Remove circuit board (left side o compartment) Being very careful to remove wires and leads, Transfer wires and leads to DINO board and replace.. due to slightly different (better) mounts I added a couple ZIP TIE wire ties to hold it in place.
I also clear coated the Dino board for corrosion inhibition but this is optional.
