    Does the Unit have Reliatel Controls? Is it a Texas Instuments board? If so then it is a high limit fault.

    Thank you P 10. I was just checking some othe manuals I have for a 2004 unit. Both limits in series. If either breaks gives you a "4" flash of the green LED.

    Thanks for you time! Mr HVAC
