LED lights faded and eventually disappeared

First, I turned off the circuit breaker to the double over.
Second, I opened the oven door. At the top of the frame, underneath the panel are four screws (not evenly spaced) that I removed. I held onto the glass control panel, not wanting it to come down when I removed the screws, but this was unnecessary as there is a ridge in the back to keep it in place.
Third, I lifted out the glass control panel. There are two sets of wires going from the oven to the control panel. One set of wire connects in two places (three connections in total).
Fourth, I simply disconnected these wires from the chips (lifting them off), trivial. They all have different connectors, so there is no chance of getting them mixed up. If you have never touched any new electronics and are completely unfamiliar with plugging wires on a chip, you may take note of the orientations of the connectors), but it is fairly dummy-proof.
Fifth, there are four screws holding the display in place. Used the socket wrench for these (they go through the holes you see on the side of the unit in the picture).
Sixth, reversed the last operation, screwing the new display in place on the removed panel.
Seventh, Some of the teeth on the connector of my new display were bent over. I bent these straight so the connector would go over them, and reconnected the wires, carefully(!)
Eighth, slipped the glass panel in place. When seated properly, it does not shift.
Ninth, secured panel with the four initial screws.
Tenth, turned on the circuit breaker.
Eleventh, was shocked by how bright the new LED was!
