My house was built 2 years ago and I have bathroom vent fans that run on low all the time, to my understanding this is a process for venting to meet code in a high efficiency home. When you flip the switch the fan goes on high speed and then back down when turned off.However, one of the fans has been stuck on high for a couple months and time to fix it. Any idea what the culprit might be? Fans say Select on them but not sure if brand or model. via /r/DIY https://ift.tt/2HBvWIn
