Is there any error code onboard in unit?

Expert:  airheatman replied 1 month ago.

If there is an error code we will do some troubleshooting to see what is causing blower to stay on.

dont want tex email only
Expert:  airheatman replied 1 month ago.

Yes I am here. Do you see a legend on the unit to tell us what the blinks indicate? And are you in heat mode or cool mode?

Normally the only time fan would run with thermostat wires disconnected is if we had an open limit or pressure switch in heat mode

not at job shite
Expert:  airheatman replied 1 month ago.

Usually blinking in cool mode just indicates power or cfms. I do not have a manual for this particular unit so do not have a legend.

If you can look on unit when you get back and see if there is a legend as well as possibly get me some pics of boards and diagrams will be a great help.Most cases when fan runs with thermostat disconnected, the fan relay (built into board) has stuck closed and requires replacement of board
