The plastic piece that connected the oven to the knob broke. and it required taking apart the whole top of the oven to fix. the replacement part was not expensive, but i didn't want this to happen again or if it did to have to take apart the whole oven. this was modeled off of the original part but the connector was extended and the hole was shrunk to give a snug fit. i also made a spacer to put on so that it doesn't leave a hole for water and grease to get into.
