I'm sorry to hear the vent fan on your SMK9175 is not working properly. Samsung's over the range microwave vent fans are designed to be both quiet and powerful; if this is not the case with your unit then it is likely the result of not being installed properly, or the unit requires service.
I would suggest reviewing the installation instructions which can be downloaded through the link below, or contact your installer for assistance.

Please note that these instructions are the same for all Samsung over the range microwaves, and are not specific to any one model. If the problems persist after correcting any issues with installation, then please submit an online service request through the link below, or call 800-SAMSUNG to speak with an agent who will be happy to assist you.
