Jenn-air oven electronic display ceased working

Number one: trip the breaker on the oven. Next, I removed four screws from the bottom of the front display panel. Then, unhooked the panel and gently placed it on the counter next to it. Then I un-plugged each of the three inputs and plugged them into the new component. I then unscrewed the four hex screws from assembly and removed the old unit. I reversed the process and screwed it back in, and when I turned on the circuit breaker, everything worked as advertised. Total time: less than 15 minutes.
