circulating basement air with goodman gmv95 furnace
When I moved into to my current house, the former owner mentioned that the furnace (Goodman GMV95) could circulate the cool basement air during the summer. It's now summer, and I can't manage to get this function working.
On the thermostat, there is a fan switch that indicates on and auto; there's also a switch that has heat, off, or cool (we don't have a/c). I've tried putting it on off, with fan switched to on, on cool with fan switched to on. Neither gets the furnace working.
I also noticed that on the furnace, on the lower right side, there's a small metal switch (the one's that look like a little stick) that it in the down position right now. Is this what I need to switch on?
I've looked at the manual (which doesn't even mention this switch-is it an add-on?), and googled. Haven't come up with anything.
Any help would be greatly appreciated.

If you pull out the stick, this may turn on the fan, however, that should not be necessary if the thermostat is hooked up properly - it should turn on the fan whether it's set to A/C, off or Heat, provided there is electricity to the furnace (sometimes there's a separate electrical switch for that, often in the furnace room.)
Note that there are several threads discussing running the fan in the summer, which is not that cheap. Search this forum for "furnace fan*". Here's a sample.

Many heat only systems only have 2-wires at the stat.
Remove the t-stat to check.
If there are only two wires, the best option is to get a 5+ conductor wire pulled to...
- Control fan from the t-stat
- Have the stat powered by the furnace so batteries don't need to be replaced once a year
- Proper 2-stage control (new t-stat required, most likely)

As 57 suggested flip the switch and see. My furnace has a summer time toggle which runs the fan on LOW. Don't forget your furnace will be pulling warm air from the returns and blowing it back unless you adjust the vents.
