The reason I got this part, is that all of the lights on the display we’re getting dimmer, dimmer, and so I knew something had to be done. I decided, to just take it apart and see what was going on. I unscrew the four screws that release the panel at the top of the oven. Then I realized all I had to do was order the part on the inside unscrew the old one and put the new one in connecting it up the same way it was originally. So the part arrived, and I replaced. Case closed it works just great and I save myself a huge labor bill.
