I have a Lennox G12Q3-120-6 model furnace. Does anyone know if there's a way to manually run just the blower without heat?
There are no switches on the outside that I can see (other than the power cut-off), and the only 2 panels are only to be removed when servicing.
FYI - I want to be able to use my furnace blower to circulate air from my basement to my upstairs.
