This rivet is an inch and a half long. It is used for many washing machines, microwaves, refrigerators, dryers, and ranges. Use of this rivet requires a rivet tool.
Using a flat-head screw driver, I removed the 1 screw from the small "door" on the back, upper right corner. Once the screw was removed, it allowed the door plate to "pop" open; exposing the old bulb. I removed the old bulb; replaced it with the new one. DONE!
There was nothing to actually, I just put in the bottom of the oven and cooked my sausage about 40 seconds later there is a loud POP and that's it. End of repair, end of breakfast, end of oven. I am returning the glass tray to you and asking for a refund. It was less expensive to go buy a new oven then to have that 30 year old repaired!
I do thank you for you prompt service and shipping. We can't say we didn't try.
