Have no fear, it’s normal for the SUB to make a noise while it’s cooling the mini-keg. It means the cooling fans are busy at work chilling your beer! It will quiet down once the beer is down to the correct temperature.
If you feel that the noise is excessive try the trouble-shooting tactics below.
- Try a different outlet
- Wait at least 1 hour after inserting a mini-keg
- Unplug the SUB for 1 hour and then plug in again
Also keep in mind that if your issue relates to cooling time, the cooling process for unrefrigerated mini-kegs may take up to 3-4 hours, as the SUB needs to work harder to bring the beer down to temperature. For faster serving, we recommend storing all mini-kegs in the fridge.
If none of these steps work, please contact us using our support form and, if possible, include a video of your SUB malfunctioning.
