  If your Airstream Controller display is not working, several issues could be the cause. First, check the circuit breaker at the service panel to ensure it is on and not tripped. Then, make sure the wiring is correct. If those aren't the problem, replace the F6 input fuse, adjust the voltage selector switch, and ensure the display board interconnect cable is plugged into the power supply board.

  If the ITA-6 alarm pilot light is illuminated, but the alarm isn't active on your Airstream Controller, there are a few potential causes. You can try the following: * Replace the F4 alarm fuse. * Plug in the display board interconnect cable. * Ensure the wiring is correct. If these steps don't resolve the issue, listen for a clicking sound when the alarm pilot light turns on. If there's no clicking sound, or the issue persists, contact your distributor to repair the controller, as the ITA-6 alarm or the ITA-6 itself may be defective.
