      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.

this is a basic Viking Range, 6 burners with a griddle and glow coil ignition in the oven.  Whats going on with it?  There is nothing in regard to a service manual for this unit.

Initially the large oven burners were lighting but not maintaining enough flame. The ignitors had low current, I can't remember the values but they were close to 3.2 ohms. Both were doing it so I replaced the gas valve. At that point there is no change in performance so I replaced the ignitors. Resistance on old ignitors was too high. Now the igniters won't even glow. Not getting voltage at igniters.

Sounds like the ignition circuit is miswired.  Lets do this, there are 2 red wires coming out of the lower right corner of the side panel.  Those wires go direct to the igniters, one to each igniter, the other igniter wire goes to for the right ignition wire goes to the white wire coming off the back of the safety valve and the left side igniter plugs right into the safety valve.  If the safety valve is open, the igniters won't glow.  If there is no power present at all there is a wiring diagram on the rear of the unit.  The only other thing that would cause an issue is the thermostat, there is nothing else in the circuit.  Please let me know if you have any questions.

I had wondered if the valve could be reversed in polarity. Since it is AC I didn't think it would matter in this case.
