Humming and buzzing on micro SMH9187B when door is closed.

Samsung support did not address this question.  I have unplugged power overnight to see if it re-sets but humming/buzz still there. Anyone have experienced this issue?

Hey there! I can certainly understand your concerns and am delighted to assist you! Do you know if the microwave is heating up when it's doing this? You can check by placing a bowl or cup of water in the microwave and letting it sit in there for about a minute.  If it is, I recommend following the steps in this link: 


However, if these steps do not resolve the issue, we would recommend service as the next step. There are a few options here we can take based on your warranty status.
If you’re in the one-year manufacturer’s warranty, please gather together the full model and serial number of your unit, and have ready your name, street address, 2 phone numbers (Best contact, alternative number), email, and place of purchase. Provide this information to an agent, in one of the following options below:
1.) Reach out to a Moderator directly, by selecting our name and the message option. When messaging please use a link to this thread in addition to the info above.
2.) Reach out to us on Facebook or Twitter. Please provide the same info as above, as well as the link to your thread.
3.) You can also contact 1-800-726-7864, if you’d like to speak with a live agent about this situation.
4.) Last, if you wish to speak with a live agent and don’t want to call in, you can reach out to our Live Chat team.
If you’re out of the one-year manufacturer’s warranty:
1. You can utilize this link to locate an authorized service center in your area to obtain estimates for repairs: http://www.Samsung.com/us/support/service/location or reach out to any local repair shop.
2. The other option, would be a replacement of the unit. Samsung.com offers amazing deals on different models that may be to your liking, check out those deals here: https://www.samsung.com/us/microwaves/
