How to Check Magic Chef Ignition Switches

Magic Chef ranges and cooktops use ignition switches along the top of the console to control the various burners on the appliance surface. The ignition switch connects to the gas igniter, which heats quickly when the switch is activated. At a certain temperature, the igniter signals the gas valve, which opens to light the burner. If the switch stops working, the burner connected to it will not light. Testing an ignition switch involves a simple check with an ohmmeter.
