I have an old Viking with a recently replaced Invensys

Customer Question

I have an old Viking with a recently replaced Invensys ignition module.
The ignition module has a separate 120 volt input for each burner.
Everything works normally EXCEPT:
When one of the burners is lit, the other burner on the same side of the stove will not spark unless the originally lit burner is turned off, then it will spark immediately. Same on both sides of the stove.
It seems like the “burner lit” signal through ground from the first burner lit also is signaling that the other burner is lit, so the other burner won’t spark.

Thanks for counting on us to help with your appliance problem. My name is ***** ***** I look forward to helping you! The most common cause of spark issues is with the ceramic electrodes being cracker, poor ground to the range and a poor path from the igniter electrode to the burner base. Also, if the wiring is in rough shape or pinced, you may see that issue. Use sand paper to clean the igniter electrodes and the areas that they spark to. Any change at all?

did you get my reply to your email yesterday?

The module you have installed has one line voltage input, one neutral input, one ground and four burner outputs. Did you sand the igniters and burners as suggested?
