no it doesn't

Thank you.

There is circuit board in the furnace where the thermostat wires attach.

Do you know the board I refer to?

You are currently hooked to R and W for Heat

R = 24v
W= Heat signal.

R to G = fan.

You can put jumper between R and G...or you can install a simple fan switch with the 2 wires coming R and G. can mount a 2 wire thermostat that kicks on blower at a set temp IF you run a constant loop.
