Many customers call me about a gas stove top that keeps clicking. This almost always happens after something has either boiled over or spilled onto the burner control knobs. The liquid from the boilover enters the switches and shorts them out. If its just water, or a thin liquid, you may be able to let it dry out.
I recommend unplugging it or turning off the breaker for at least 48 hours. If it still clicks or doesn’t work to light the stove top after that, you will probably need to have the switch replaced on the stove top burners.
Some of the switch replacements are a relatively straightforward job, while others can be a little tedious. If you are in the Katy area and have this problem, let us know if you need our help.
