For the EXPERTS

I have a Goodman GMS8 furnace with air. The manual slow speed fan setting was never hooked up at the thermostat. I believe it is just a matter of jumpering the terminals to engage the slow speed fan. If this is correct what terminals (at the furnace) do I jumper on the circuit board. The board is the standard White Rogers circuit board.

Thanks I

Look for a diagram somewhere on the furnace or look in your owners manual.

What is the white Rodgers board model number and I will see if I can look it up.
