spark for gas range burner continues non-stop
The electric spark for my gas range burner continues sparking non-stop, regardless of the state of the burners or burner controls. The problem started by itself suddenly, with no apparent cause or provocation. Problems occurs when all burners are turned off, and when any burner is lit. Burners light properly when the knob is turned to enable flow of gas, yet sparking continues non-stop. I have to disconnect the power to get it to stop.
Model number of the stove is Viking VGSC3064BSS.
