Diagnostic Codes
The Amigo controller has a built-in diagnostic feature that will
cause the diagnostic LED lights (Figure 21) 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 call the Amigo service department at (800) 248-9131
or (989) 777-0910 for instructions to verify and correct the problem.
