In case you did not get my furnace information it is a Carrier Model 58GS 150-2, I checked the thermostat by removing it from the wall and the fan kept running. . I also replaced the circuit board 302075-302 in case the relay switches were not working properly. . If you need any more information about the furnace please let me know.

Yes I am still here, if the blower stays running disconnect the G thermostat wire from the board and see if it stops

Customer: replied 8 months ago.
I will check it tomorrow, I am going to bed now. I am pretty sure it still ran when I disconnected the r wire at the board when I was checking to see if there was continuity at the thermostat with the thermostat in the off position.

Disconnecting the G wire does not cause it to stop
Customer: replied 8 months ago.
I hope you got my message that the blower does not stop running when I disconnect the G wire.
