Lifted range top, disconnected and labled wires from old switch, removed old switch, replaced wires on new switch, installed new switch. NOTE: Local appliance store informed me that the electric cooktop was too old and that a replacement switch was not available and wanted to sell me a new cooktop for $795! I found the switch on PartSelect and repaired the cooktop. Total cost... UNDER THIRTY DOLLARS!!
Turned power completely off. Removed knob from front panel. Opened range top cover. Removed 3 screws from aluminum panel protector behind the element switch. Once panel is removed you can see the switch element. Remove 2 screws from the front panel that connects to the element switch. Remove the old element and replace with new element making sure that each of the 5 wires on the old element is transferred one by one to the new element. Reverse the process in putting it all together. Turn on the power and walla you've have a new stove. You just save $600 plus.
I found the received switch (PS12070192) a poor replacement for the original, or even the earlier replaced part (PS11744446, in 2016) I was going to replace since the press/return feature seemed slow to return.
The male spade lugs on the received switch are so positioned that engagement is only possible if the lug is bent out at a large angle. The lug set-back from the body edge, and the raised ribs on the sides still prevent full engagement of the connections.
I did install the new switch but found that was the only switch that didn’t give a signal light when turned on.
