Circuit board resource for RM 3804

I think the circuit board at the top of the Dometic RM 3894 Refrigerator in my 1990 Land Yacht is not working. I replaced the cooling unit and it has been working fine until the hot lead to the heating element/gas pilot light shorted to the case. It blew a fuse at the box, but before I realized I had a direct short, I replace the fuse, which promptly blew out again, of course. It was then all the lights went out at the control panel at the top of the fridge. I now cannot get the unit to work on AC or gas. The fuse at the ignitor near the heating element shows that it is not blown.

It seems PPL Motorhomes in TX does not carry the replacement circuit board. Any ideas who may have it? Should I try something else before replacing?

check for 12v power at the fridgee. you might have blown a fuse for that circuit in the coach. use a test light or a meter since the eyes can get fooled.

Anyone who carries Dinosaur boards should be able to get it, their site says it's a Micro P-246 Plus.
