    I have a Rudd system. The problem is the draft inducer turns on, the pilot lights the burners, the furnace fan turns on and runs for 8 minutes. The furnace and burner turn off but the draft inducer stays on. The burner relights, the furnace turns on and runs agian for 8 minutes. The system will do this several times until the temperture in the house goes up 2 degrees higher than the thermestat. Then it will finally shut down everything and stay off until the house cools down to about 2 degrees lower than the thermestat is set at. The system use to run continuesly until it eached the set temperture. What could be wrong?

    check your filter and make sure its clean. also check that all of your vents are open. if both of those thing are ok, its time to call for service.

    Sounds like its cycling on the limit. Filter clean or do you have a round Honeywell thermostat?

    If it is cycling on high limit then the main blower would remain on as well as the inducer.

    Is it a 90+? Could be a slow drain or a sag in the vent pipe. I'm betting on some sort of pressure switch issue.

    Post Model number.

    dj, after reading some of your replies, you might not want to be throwing rocks. That's a pretty empty glass house in which you reside. Take it easy and learn a little without bashing our members.
    Perhaps you should have read the instructions before calling.
