I have a Coleman furnace, model 7966 A856. The furnace starts up, fan comes on, then shuts down fairly quick. The burner keeps going, and the fan comes on shortly, but only for a short time. This continues until eventually it stays on. I think it may be the fan switch, but would like another opinion. Any ideas?

Could be a bad fan switch or something causing it to open early and close.



Thanks,
Robert
