I have a cmf2 80-PO oil furnace, would there be any reason for the blower to run for only a few seconds (3 - 4) after a burn? It will do this 2 or 3 times after every run.

The fan OFF setting is probably set a bit too high. The unit soaks up heat and cycles again until finally cooling off. Is this unit run from a motherboard?

Does the fan stay on longer on each run until it runs until the call for heat has ended?

Hey Grady, good to see you back.

Drakey112,

After reading your question again, I too would question the fan control settings.
