Does the fan keep blowing or does it shut down.

Customer: replied 6 months ago.
It is blowing cold air instead of hot, I checked the control board for an error message of any kind I couldn't find any and the furnace Simms to be fine too.

SO sorry about wait. Tornado in area and lost power. This a gas furnace correct. If there is no message on board and furnace operates ok. Sounds like a bad relay on board. If you can give me model number I can check the wiring diagram to make sure. Russ
