Here's my problem. I pulled out the burner and cleaned it as you recommended as well as the orifice and it now will light with a bright blue flame.....was getting nothing before. It stays on for about 10 seconds.....maybe slightly more, but not long......then goes out. So, according to the manual it is either the electrode flame sensor, or it is the board. I'm inclined to buy the replacement electrode first....can't hurt....hoping it is that simple. How do I test the sensor to see if it is sending a signal to the module board?
