That is the right thing to change since those relays are on the board. A board from Flight or ASAP should work fine. The K-15 relay is probably going bad or a solder joint, connection. Is failing. I have replaced those boards on DKD's. I had a customer who had one mounted in the back of a Ford diesel Van. She had show dogs. Dobermans. I also recall one Ina Motorhome. It was stored in a big barn on a horse farm. That was the only MH I ever saw with a DKD. A diesel pusher. Generator was up front on a power slide. Hope the board fixes it for you.
