    I am working in Iraq and we have a Carrier “Crystal” unit that was just installed a few weeks ago, and was working fine, until we had an electrical issue with out Junction Box. That has now been resolved, but when you turn on the unit, it shuts down within 3-4 minutes and then displays an E-9 Error code. Please offer any help you can, thanks!
