My flat top stove of about 5 years old ( Kenmore) still properly heated correctly but the "element On" light on the back panel which is shared by all 4 burners would stay on even if all burners were turned off. This new front left surface element switch solved the problem. Inside the switch it was charred which was causing leakage current to flow to keep the light on. I could tell it was the front left because the light was slightly dimmer when this burner was turned on vs. the other three burners which turned the light on a little brighter. The repair was easy, removing the 5 rear panel screws allowed me to access the switch wiring which just unplugged with a little force, re-wired the new switch the exact same way by removing one wire then putting it back on the new switch in the same spot. Removed the knob and two mounting screws, freed the old switch and the new switch was easily re mounted. Even cleaned the stove and behind it, found about 35 cents too!
