Hello and thanks for using this service, if you have been waiting do not worry or get upset. I am APPLIANCE-HVAC GURU a very experienced tech on here and I try to get to as many customers as I can. I just picked up your question now.

Please allow time for me to respond, sometimes I get the questions or responses late so please be patient as I have no control over the site issues. NOTE, I have nothing to do with your payment to the site and did not receive that money.

Lastly the only way to credit me "APPLIANCE-HVAC GURU" is to STAR RATE my post......NOT another TECHS when we are finished otherwise I will receive no credit.....Thank you!

Do the electrodes spark?

no they do not, I checked what I believe is the main box, no codes seem to be present

I can see fuel mist through the sight hole
Expert:  HVAC Guru replied 9 months ago.

I would say you have a bad ignition control then or a wire broken from the electrodes to the ignition control box. Can you check the wiring?
