It might be fine. I would run it all the time im home and see if it goes away. Maybe after a while whatever is causing the smell with "burn" off or evaporate or whateverI'm going to run it again for a few hours tonight before I decide what to do. I found myself chatting with the woman that sold it to me because she accidentally forgot to send the power cord initially, no biggy. She was so grateful that I was understanding and eventually told me that she is going through breast cancer treatment...so now I don't have the heart to ask her about the smell because she's going through enough. I may just count my losses on this one. Oh well! We live and we learn...to buy new incubators.![]()
