Jenn-Air JED8345ADB Knob Fix?

[TMeitner]

So we have a Jenn-Air downdraft cooktop and one of the range knobs doesn't work anymore. The two small screws on the inside came loose and fell out.

As best as I can tell, the screws go into the first hole and through the second hole, pushing against the metal in the back which then puts tension on the pin. My problem is, I can't get a screw in there because I have to lift up on the pin to lift that middle piece (the "second hole), and the metal in the back keeps the screw from advancing and catching on that middle piece.

Boy, I hope I'm explaining that clearly enough.

In short: how do I get a couple screws into this pin assembly so that I can use the knob again? The whole cooktop is one piece so I can't just pull out the switch and replace it.

Do you still have the screw?

Be careful leaving this unit plugged into the power - if that surface control switch drops down into the unit the terminals can short out on the metal casing.

If you still have the screws that fell out - unplug the unit before you start.

Carefully pull the knob with the switch assembly still attached up as high as you can and get needle nose pliers or better if you have think wire stripping pliers get them under the know so you can get a hold of the switch/knob shaft and hold the assembly up and pull the knob off and put the screws back in.

If you have already pulled the knob off and the switch and shaft has already fell down into the cooktop and you can't get a hold of the knob shaft to pull it back up then you got some major work, (would have to pull the cooktop and separate the top from the lower pan so you can get the control switch backup into place then screw the screws back in to hold the swtich assembly to the surface of the cooktop.

The knob itself slides right off. The shaft hasn't fallen down into it, it just dropped a little. The problem is I can't get the screw to go in at all because when you pull up on the shaft, the metal underneath also moves up and pushes against the screw through the hole, so the screw can't catch.

NEVER MIND EVERYBODY! I figured out that the holes just weren't lined up. I had to really push that middle washer with a toothpick until I revealed the hole through that last bit of metal attached to the shaft. Popped a screw in there and we're good to go!

Glad you figured it out - the rubber gasket is separate and moved out of position after the screws cam out.

You did exactly what was required.
