I have a 5 year old Lennox furnace-model number G50UH-36B-090-03. The "pre fan" comes on, and then the burners, but the main fan won't start up.

I have a 5 year old Lennox furnace-model number G50UH-36B-090-03. The "pre fan" comes on, and then the burners, but the main fan won't start up.
Does the fan run when the thermostat is set to fan ON?
