Diagnostic codes

The Amigo controller has a built-in diagnostic feature that will cause the diagnostic LED lights to flash a numeric code, indicating service issues to aid in diagnosis. When indicating a service problem, the diagnostic lights will flash, hesitate for a moment, and then flash again. Follow the code listings below to determine the problem. Solutions should be attempted in the order they are written. If the code indicates a service problem, contact your local service representative or contact the Amigo service department at 800-248-9131 or 989-777-0910 for instructions to verify and correct the problem.
