Hi all,Passive solar house. We have a fan that's in the wall upstairs that is controlled by a thermostat. Lately, it's been really squeaky, and today I got home and I could hear that electricity was running to it, but the fan wasn't turning. We just moved in a few weeks ago, so no clue on make, model, anything like that. Not even really sure how it works apart from controlled by the thermostat that goes thru the wall onto our balcony.Any thoughts? It's in the mid 90's here and we don't have AC so hoping I can do something to get it turning before having someone come look at it.Link to images: https://ift.tt/2XitL5N is the thermostat. No idea what the white box is. The vent is way high up the wall. Last pic is the thermometer (I think) that's outside. via /r/DIY https://ift.tt/2XhpVcY
