Not sure on the newells but on my Peterbilt's that have this type fan that is how they work when you unplug the relay it is in manual mode and will run on high ..... when plugin it runs off the temp sensor ..... that being said I would call and check with newell, if it gets too hot that is very expensive if you crack a head
