Troubleshooting Guide
In order for the on-call Technician to troubleshoot the
problem(s) you are experiencing and render the best possible
solution, it is necessary that you be at your RV when you place
your call.
1. If the display is illuminated and scrolling information, note
the Error Code. If there is an Error Code of 1-8, the device
will interrupt the power. See Error Chart for definition of
AC power problem. The device being off when an Error
Code is present indicates the product is working properly
and protecting your coach.
2. If the display is illuminated and reading Error Code E0, and
yet no power is present in the coach, please contact
Technical Support. You must wait 136 seconds for the
time delay light to stop flashing.
3. If the display is not illuminated and power is in the coach
there is a connection issue between the display and the
main control box. Contact Technical Support.
Technical Support can only help if the above information is
provided, therefore, please do not call until this information is
obtained. Again, it is necessary for you to be at the RV when you
place your call.
