Furnace Blower

[ndunn]

Does anyone know how to get the furnace blower to work without having the burners lighted? Would like to circulate air without the furnace being activated.

I do not. However, in my rig when I want to do what you are asking, I don't use the furnace at all. I use the air conditioner set to fan only.

You can't from the thermostat, you would have to wire a switch to send power to the furnace fan. I use the AC fan to circulate the air and provide background noise at night.

I found a wiring diagram of the furnace and will wire in a switch that will bypass the time delay switch to the motor.

Make sure that the bypass only runs the fan. The time delay ordinarily allows the fan to purge the airway before the firebox is ignited. Bypassing the time delay might allow the firebox to ignite with vapors present. Not good. That's why the delay was developed. Not trying to imply you're off track. Just trying to make sure you stay safe.
