Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.
Do you want to know what your unit's flash code is or do you want the entire range of error messages?

Expert:  Rick replied 1 year ago.

Both lights flashing together indicates normal operation.

Both light flashing alternately indicates a flame/ignition failure
