GE XL1800 Microwave Buzz

All of a sudden this starts happening. Opening the door I hear a pretty loud buzzing sound. It will still heat food. The turntable stopped working and the vent has trouble opening and closing. Sometimes it just doesn’t open. The buzz occurs until you clear the microwave time. Just pausing doesn’t do it.

Is this salvageable? Maybe a DIY job?

Here’s how it sounds up on youtube. I suspect links will blocked here so I split it out. Put a slash in the link below

Thanks for the help
