This is the second one on our 4-burner GE cooktop. I'm glad APP had the parts and got them to me quickly.
To any new DIYers, this is not a difficult fix.
I do it without disconnecting the cooktop from the junction box, just turn off the breaker and lift it out, unscrew two levels of screws until you get to the elements themselves. Use needle-nose pliers to unclip the hooks, unplug it and it's out.
I squirt the leads with a little WD-40, which is flammable so not that much, ease the wiring harness back together, wipe it down and put it back together in the hole on our countertops.
I did this fix during the halftime of the Mavericks-Knicks game and got back to watching about halfway through the 3rd quarter ... bada bing, bada boom, and the Mavs won, not a bad night.
