I finally had a chance to come back around to this. I pulled the igniter today. It doesn't seem 'dirty' to me. The gap is over 1/8 inch though. I tried to squeeze it back together.
Weird thing is, it will start just fine every time we start it manually on 'Both' mode.
Should I pull the igniter again and clean the ends better?
Is there something else to check?
Here are some pics of the igniter.
