Can a faulty infinite switch burn out the rocker switch. I tested the resistivity of the rocker switch and it was fine for the large element but was reading infinite resistance for the inner element. I don't want to buy a new rocker switch then have it burn out immediately due to another issue. Thanks

Barry for Model Number MER5775RCS

ANSWER Barry, The Rocker switch 7403P985-60 only comes into play, when you select it to activate the third element. When you press the switch, the circuit "closes" and allows 120 VAC (L1) to one side of the element. When the button is deselected, the circuit "opens" (infinite resistance) and the 120 VAC L1 power stops at the rocker switch(only the single or double elements work, depending on the infinite switch selection / position). Yes a faulty infinite switch could damage a rocker switch, as could a shorted wire or element, but at this point, the rocker switch is working properly based on your post information.
