I had the same problem. I found that two of the small pin connectors on the ends of the wire from the ignitor had come out of the ignitor button thingy. If you push back on the stove top then lift up you can raise the burner top to expose the burners and the ignitor. Likely the connector has come out of the ignitor or has shorted out as previously mentioned.
