Repairing the oven heating element required finding the proper model number. That is on the edge of the oven cavity (not inside). Open the door and it is on the top right. Once that information was entered into the "Pros" system – bingo! The part arrived quickly, as promised. I watched the video and a couple of others on the web. They work in what appears to be a new clean oven. I think some of them cheat.
To take the non-functioning element out requires the removal of two metal screws. The operative word needed is "torque". Fitting a small screw driver into the screw head at the bottom/back is a stretch. [I didn't attempt to take the door off.] Getting the small screw driver to turn was impossible. I tried a couple of improvisations. I'm no longer young, so getting up and down and inserting myself into the oven several times required a nap.
I reverted to an impact driver with a #2 Phillips-head (+). That worked. The next step – removing the slip-on electrical connectors – did not fit the idea of easy and fast. I wiggled one off and the other bent and broke. The connectors on the heating element have an angle approaching 90%. Laying across the oven door and reaching to the back is not conducive to pulling in the right direction. Enough of the connector stuck out of the slip-on connector so that I could grab it with blunt nose pliers. With careful wiggling I pulled it out. Did I mention I was half on the floor and half in the oven. Oh – I should mention that with the power off there is need of a light. I got the wires connected and struggled a bit with the screws. Finally, I managed that, closed the door, turned the power on and gave it a quick check. It appears to be fine. Tomorrow – brownies!
