91147962100 Kenmore Microwave Oven Combo - Overview

After turning off the breaker to cut power to the oven, I opened the oven door and, using the PartSelect exploded diagram as a guide, I removed 3 screws from the underside of the control panel - I was then able to slide the panel up and out to remove it. Leaving all of the control wires (especially the ribbon) connected to control panel, I saw the fan assembly mounted to the rear of the control box.

I noted the position of the two attached wires - black on top (or left), white on bottom (or right). Using a nutdriver with an extension bar, I unscrewed 4 screws holding the assembly in place. I removed the old fan and installed the new fan in its place. It was necessary to bend the new fan's legs out a bit to get them to line up with the holes. I reconnected the wires as mentioned above, then reinstalled the control panel.

I tested the oven by turning the breaker back on and letting the oven heat up to 450 degrees. The fan turned on as expected. After the oven cooled off, I reinstalled the 3 screws to secure the control panel.

removed two phillips screws. Unplugged electrical connections replaced unit from PartSelect. They sent holder cover and new bulb (surprise). Great store with great directions.

Most important: Unplug or turn off the breaker before beginning! (I briefly saw sparks as I removed the old switch.) Look at the replacement switch. The springs on the sides hold the switch in, which means you have to press in these springs to get the old switch out. I slipped a small screwdriver in on the side while I pulled with a small pair of pliers. It's tricky, but it will come out. Once you have the switch out, just unplug the wire in the back, making sure it doesn't fall back in the hole before you get the new switch on. Then, just push the new switch into the hole in the stove and you're done.
