Quiet a Dr Browns bottle dryer

Our Dr.Browns bottle dryer works great, unfortunately it has an obnoxious "I'm done" beep that can be heard throughout the house. A simple fix will be demonstrated in this video. Masking tape and a T10 Torx L-Key are required.

Thanks for the video. I had just opened mine up mainly to oil the blower fan cause it was getting loud. I did your mod also with some tape on the speaker. So much more quiet now, not sure why they come from factory like that.

Mine stopped drying well do you think is the driver board or the thermostat???
