We’re happy to hear your new microwave is working well. Microwaves make a wide range of noises during operation, and we suggest checking out the article below for more information. https://products.geappliances.com/appliance/gea-support-search-content?contentId=15900 If none of that helps, or if you believe the noise you’re hearing is beyond normal operation, we recommend taking a look at page 15 of your use and care manual, linked below, to learn how to take advantage of your warranty. https://products-salsify.geappliances.com/image/upload/s--uukLF7Nu--/c35e23730934736d1049ac39da6daf25ac49e81c.pdf
