Look on control board and tell me if you have a green light blinking and if so how many flashes between pausing?
OK here is what the lights mean.
First green-power to unit
Second green -Error (flashes a certain number depending on error)
Yellow-FLAME. This would should only be on when burners are on.If it flickers or blinks that implies marginal flame is being sensed.
Since the yellow is blinking, lets start by cleaning the flame sensor with a dollar bill or fine sand cloth,
I will attach a pic and a link to a sample video of how to do this.The flame sensor will b in front of farthest burner from igniter and have a single orange wire attached.
Now video will not be exactly like your furnace but will give you the idea
First of all, if you have got an error code, the blower is going to stay on and igniter will not light until you correct the problem or turn power off and back on to unit.In original question you stated igniter came on , burners and burners lit.That implies ignitor is ok. Lets do this.Clean that flame sensor, Turn power off to furnace then back on.That will reset board.Then lets see if furnace will operate correctly.
