Russ here. Check the filters first to see if stopped up. If they are dirty the furnace may cycle on high limit. Russ

Does the fan keep blowing or does it shut down.

Customer: replied 16 days 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
