I purchased a WB24X29364; the newer, compatible control. This control has the spade connectors on the side - the original part has the connectors on the bottom. I could not get the wires to relocate to the side connectors, so I had to rotate the control 90 deg to makes things fit. Fortunately my wife is prepared to live with that till I get an exact replacement WB23K5052.
I deduced the original problem was the Black connector - it looked different from the others and I think it had been heating up, so I squeezed the female spade connector with pliers to get a snug fit.
I found the YouTube video very useful. My concern had been removing the unit for repair, but it turnout the installer had made an accurate hole in the counter-top and secured it with silicon bathtub caulk
