All 4 gas burners will not ignite. No clicking sound is heard, but can light with a match. Seemed to have this problem after my wife cooked rice that boiled over. I've done that in past, but never caused a problem. Initially, after the rice boiled over, 1 burner lit and the others still clicked but didn't ignite. Now none click or igniite. How do you figure out if it's the ignition module or ignitor, etc. Thanks for your help. Can unplugging this duel fuel range help and waiting hrs. to plug it in?
