Remove the exhaust hood, make sure the exhaust system isnt restricted. While mine was running it was producing almost 80dB! removing my exhaust reduced it almost to a whisper (Something in the exhaust hood was pinning the flap if using external venting). When the exhaust is restricted it runs very loud, fan speed increases. Wish GE manuals/responses was more descriptive than saying noise while running is normal, they dont account for this simple issue.
Sorry, there was a problem. Please try again later.That's not my experience. Mine is very quiet, especially compared to the 10 year old model it replaced.

Over-the-range microwaves have an automatic fan feature to help protect the electronic components, and also helps the cooking area get rid of excess heat. The built-in thermostat automatically turns the vent fan on if the unit is too hot, and will not turn off until the microwave is cool again. You will not be able to turn the vent fan off manually during this time. We hope this helps! Emily@GEA
