the fancy tests on flame sensors but by and large have found I am better off just to change the flame rod and be gone. If I do not have that flame rod on the truck I clean the old one (I know you can't clean a mushroom nor do you need to test it) and put it back in most of the time it will work til I can get one. I also make sure the ground is bright and tight. J. Lockard
