How do I turn on an auto ignition stove?
A couple of things. First, you just bought it, it surely came with a manual, you should check there to make sure you're doing it right.

In general there are a couple of things that come to mind:


You may need to turn the burner to high to get it to ignite.
You may not be waiting long enough. It takes a few seconds (at least on mine).
There may be something wrong with your stove. For example, maybe the burners aren't installed properly. You're seeing the spark, so that part is obviously working. If giving it a few seconds on high doesn't get it to ignite, and the manual provides no help, I'd suggest calling the manufacturer or the dealer, they'd be in the best position to diagnose a defective unit.
