Control mod LED is on constantly when burner is lit but goes out when burner goes out. I expected to find a small millivolt at the flame sensor, instead I found approx. 143 VAC and bouncing up and down the scale. Again the burner just cycles on and off. I suspect the controller to be faulty. Am I correct? How do I check the White Rogers 50D50-842?
