    The furnace stars (inducer runs) ignitor lights up and then the flame sensor turns on the blowers for about a minute or so. The furnace turns off, blows cold air and then it locks out (1 blink). The furnace does not give me any other blinks but the 1.

    It stays on for about 30 seconds at times and then a few minutes but not longer than 5 minutes

    It is possible the flame sensor is dirty. Try cleaning it.

    Are the orifices screwed in on your furnace? If so remove the offending burners orifice and make sure it is clean. Remember to use pipe dope on the threads when you screw it back in.

    All the burners light up with a blue flame. Yesterday I turned it on and it stood lit for about 10 minutes.
