Abstract
A sound sensing module for monitoring the operation of an appliance includes a microphone for monitoring sound generated during operation of the appliance and a controller operably coupled to the microphone. The controller can obtain a sound signal generated during operation of the appliance, analyze the sound signal to identify a sound signature corresponding to an operating event, and implement a responsive action, such as providing a user notification, providing troubleshooting instructions, ordering a replacement part, scheduling a maintenance visit.
