3 Secs before igniter spark on Range Top

[marknohr]

We have a Viking gas range top with spark igniters. For years it would continue sparking after the burner lit Typically a longer post sparking cycle after the stovetop was cleaned. Recently the behavior have inverted. Now it will wait 3 seconds after the gas is turned on to spark once. It ignites the first time but the delay is troubling. THe behavior is not burner specific.

I've cleaned and de-greased all the igniters and everything above the stove surface.

Could this be one bad igniter? The igniter controller? loose ground/return and if so where to look?

I'd like to pre-order the parts so I'm not pulling it apart twice.

If it's common to all burners it's probably a spark module issue.  What's the model and serial numbers of your range?

Model # VGSU101-4BSS

Serial # C02139800813

This model is fairly basic.  Looks like it uses microswitches to activate spark module, so the culprit is likely to be the module given the fact that this problem is common to all the burners.  Also check all the ground connections and the polarity and proper ground and neutral on the electrical outlet.

Part number: AP5315188

Make sure the flame from the lit burner contacts the spark electrode at the burner, these re-ignition modules use the lit flame as part of the circuit
