I pulled down the wire around the glass cover. . . Released on end of the wire from its holder being careful to not let the glass cover drop. Unscrewed the bulb and replaced with replacement. Easy, easy.
I went to the source of power on the stove and noticed one of the terminals had come loose from the terminal block and had shorted out against the cover of the terminal junction. After prying the loose terminal off cover I ordered new terminal block and received it the 2nd day. I removed the old terminal block and replaced the part in about 10 minutes..Thank you Parts Select for your easy to find diagrams and quick delivery.
This is a built-in oven, so the biggest problem was figuring out how to remove it from the cabinet. The solution turned out to be removing the cooktop above it and unscrewing two screws that connected the oven to the inside of the cabinet. The other problem was removing BOTH metal backs from the oven. The first one was easy. The second one wasn't. The old socket was recessed behind the second back, making it virtually impossible to access the metal "wings" that hold it in place, so I ended up pulling out the socket assembly from inside the oven with pliers.
27 year old Chambers Oven, Chambers out of business, Whirlpool helped
The oven light gasket had deteriorated with time and bulb changes. It is a self cleaning oven, which gets very hot during the cleaning cycle. The oven is old (27years) and off the "books" I selected a similar, but slightly smaller gasket (3" OD), and "fit" it to the 3.5" light fixture of the older oven. The gasket material was similar to the original, and I used a usable portion of the original,along with the new gasket to build a gasket for the light lense. Several years prior to this repair, I replaced the oven door springs. Whirlpool, who had taken over what was left of Chambers, had the springs. I did replace one heating element about 15 years ago. The Chamber's salesman told me that the Chambers was the "Cadillac" of all ovens, and it seems to keep running.
