Opened the microwave door, took a photo of the model and serial # and looked up the part on Google. Appliance Parts Pros came up showing the part and prices, gave them a call and confirmed the part would fit. Ordered and it arrived the next day (great price as well!). Looked again on Google "How to replace microwave control panel" (these panels are basically very similar on all microwaves. Found a youtube video and a few screws later the new panel was in. Checked and it's like new again. I'm in a rental house and just know the owner would have charged a replacement microwave from my deposit if I hadn't fixed it myself.
