Fan runs continuously

Hello,

I have a Frigidaire gas furnace model FG6RA-120C-16B. It heats fine....calls for heat, comes on, heats to desired temp. The fan starts and does not stop until call for heat again. It stops for about a minute, then heat comes on.
I have changed t-stat, filter. When wires disconnected at t-stat, fan continues. I shut down, power up, fan comes back on. Ashamed to say, I don't know how long this has been going on. While fan is on, there is a red light on the circuit board with the word "status" next to it, that blinks every second or so. There is also a "blower off" pin with settings at 60, 90, 120 and 180. Initially it was at the 90, 120 marks. I moved it to 120, 180. Didn't help. Tapped on relays after shutting furnace down, no help.
Is there something else I can try before calling pro?
Thanks!

Welcome to the forums.

Remove the wire from the G terminal at the control box and see if fan still runs.

Those numbers: 60, 90, 120, 180 are the selectable times in seconds that the blower will run after the call for heat ends.
