      All Appliantology tech members are invited to join in this workshop on all things Appliantological: bidness, customers, tools, troubleshooting, flavorite brewski, whatever. Webcams and microphones are open and live!
      This workshop is also a great time for any students at Master Samurai Tech to bring any and all questions about the coursework. We're happy to walk through any concepts you're having trouble with. Think of it like office hours with your teachers. 
      If you have a specific appliance problem you'd like us to talk about, post it here! We need a problem statement and a PDF of the tech sheet or schematic so we can all see it on screen share. If you have a PDF that isn't already in the File library here at Appliantology, send it to us by attaching it to the contact form. 
      Also, follow this Calendar Event so you'll get notified of new posts here. Look for the "Follow" button either at the top of the topic on desktop or below the topic on mobile.

Well if there is no flame the gas valve would be stuck closed.

On a call for heat use your volt meter to verify low voltage at the gas valve.

If you have voltage tap on the gas valve with the handle of a screwdriver.

This sometimes will open the valve.

If this works,replace the gas valve.

If it does not work,replace the gas valve not the control board.

If you do not have voltage at the gas valve,verify all circuits(roll out switches,pressure switches) etc. from the board to the valve.

Re-set,repair or replace the defective part.

I am sorry. When you stated the high limit circuit is closed I mistook that as power to the ignitor.
