What should I do if my furnace inducer fan wont ignite?

Is the CPU fan supposed to run constantly?
I believe on a desktop, the CPU fan is supposed to run constantly otherwise the CPU overheats and the computer shuts down.

If it was the CPU fan, it would normally be around halfway, or higher up the tower.

When do you turn on the low speed radiator fan?
12 people found this helpful. When your ac is on your low speed on the radiator fan should be running. Since it is not the high side pressures go extremely high. When the computer sees these extreme pressures it turns the high speed on to the radiator fan bringing the pressures down to normal.
