Hi,
The controller was working before or is it new and never work fine?
Is the DEC motor hot?
Have you tried to switch the RA - DEC cables in the board to check if the fault is because the controller itself or related to the cable/motor?
If it's the controller, have you tried to trim up/down a little bit the current limit potentiometer?

good look!
