This unit should be electronic ignition. Multiple issues could be the cause. First check the flame sensor. If those is not the problem then probably a bad control board. Don't know specs on the resistance of the flame sensor. You could try cleaning it with an emery cloth or sandpaper. Do not touch flame sensor with fingers it will ruin it
