Have you boiled over or spilled anything on your range, recently?

Newly reinstalled yesterday evening and as usual, cleaned in the process.

Most likely you have somehow gotten water down into the area under one of the burner knobs. Under each knob is a little electric switch that activates the igniter board. Water will conduct electricity. You best hope is that you can get the switch dried out and hopefully it didn't damage it. You could also, try to shoot some WD40 down the shaft under the knobs. It will repel water out of the area that it contacts and also lubricate the switch. You could also try blowing warm air from a hair dryer down into the shaft hole and maybe get it dried out. Be careful to just use the lightest heat setting, so you don"t end up melting something.

If non of this works, you will need to take the cooktop apart to find the offending part and replace it.
