Viking stove burner not sparking reliably
I have a 20yo Viking dual fuel range, Model: DSC365-4GBK . 36” wide with electric oven , 4 gas stove burners with a gas griddle in the center.
I have made some repairs over the years:
- Replaced oven door hinges
- Replaced oven element
- Replaced oven thermostat
- Replaced one cracked stove burner igniter
- Replaced one stove knob
Our current problem is that two stove burner igniters have stopped working reliably. The burners work perfectly as long as they are ignited, and the rear two are working just fine. However, the front two now don’t usually spark when you use the dial controller for that specific burner. The gas comes on, but you can’t get it to spark most of the time. However, if you turn one of the rear dials to spark, that will generally fire all the igniters, and if you have the gas on for one of those two problematic front burners at that time, they’ll spark and work just fine.
We tried replacing the igniter at first, but that didn’t help. Then we swapped the wire from the dial to the igniter and the igniter itself from the rear right to the front right, and visa versa. In that case the same issue happened - the front right continued not to spark, but the rear continued to work fine.
So it seems like the problem isn’t the electrical current or the igniter or the gas by themselves, but something specific to that burner. Maybe there is some corrosion in the burner that is preventing a spark from leaping to it from the igniter? It is well-used, after all. Because of their configuration you can’t move that part from one burner to another, so I don’t know what else to test/try. We’ve scrubbed away some of the rustiness in the areas around the igniter, but no improvement there. And, this is inconsistent. Sometimes we will get the igniter to work on the problematic burners, but usually not.
What could be the issue?
Good burner (installed)
Non-sparking burner
Is dit een goede vraag?
