Curtis sno Pro 3000. I switched lift coil power plug from the right angle coil and the lift operation worked when pushing the right angle button so I know the hydraulics are working correctly and switched plugs back to normal. I traced the problem to no power output at the controller when pushing the lift button. my diagnostic knowledge ends here. If I am correct I presume I have 2 options...replace controller at $200+ or repair. 1. Am I missing something in my diagnosis? 2. If I am correct does anyone know of a good & reasonable controller repair service?
