All 5 burners spark when only one burner is turned to light

Question

I’ve had my LG gas/propane stove for 15 only months. It has worked perfectly until this past week…the night prior to the following issue. I turned on the right front burner and the 4 remaining burners igniters sparked as if they were going to light…the knobs were in the ‘Off‘ position. The right front burner lit…none of the other 4 burners lit…but they sparked. I went through the same sequence with the rest of the 4 burners…results were the same. The burner being lit continued to spark even after it was lit…the knob was turned from the ‘Light’ position to the ‘Low’ position. I turned all 5 burners off & let them sit for a bit & tried to use the right front burner again…same results. Now a week later, the problem has not resolved…all burners spark when I try to use only 1 burner.

Answer 1

This is normal. It is standard in gas stoves with electronic ignition that all burners spark when any one is turned to “light”. Having four or five separate spark modules (or high-voltage switches/relays) and dedicated wiring from each burner switch would add a bunch of cost for no benefit.
