Hi there, valued customer! The sound cooling fan sounds such as:
Humming sound-This can be the normal behavior and can be heard throughout cooking cycle and after oven is shut off. This can take between 30 -60 mins.
Rattling sound- This type of noise can be heard when there is a loose connection. Please check connection. If you hear an unusual sound aside from the common sound of the fan, please reach out to us by live chat or by phone at 1-800-374-4432. Monday through Friday, 8:30 a.m. to 8:00 p.m. EST.
