A little info that may help someone in the future.
American Technology Components Inc. acquired KIB. There are still KIB folks working with them. I spoke with one today and he was very helpful.
The part number on the faceplate on mine was a Fleetwood number which made it impossible to find online. All you really need to know is the number for the board. Tip...buy it from them. I have seen boards with 300% markup from RV parts suppliers online.
They will be able to tell you what circuit board you need, if yours is cooked. They will also sell you the part.
