Sounds like the ignitor has cracked. Pull it out and check it.
don't know yet, will check when I get home from work. I am working thru this with my son and I have the VOM with me. I'll see if he can use his current detector to see if he is getting any AC at all off the board/igniter connection
More than likely. You can determine that by taking the leads off and checking for continuity between the terminals when the vent motor is running. But I think the problem is with the ignitor.
