I bought a heating element online from China for a few bucks and had the rest of the old incubator. The heating element stinks. I mean really stinks like burnt oil. I hope that will go away after awhile. I had to hook up a fan from another incubator, a thermostat from another one and finally they all made it to my first incubator. Oh it's confusing. So far she reads 37.5 so I must be doing something right. I had to strip wires and hot glue the bare wires. I know what bare wires do when they touch. Been there done that once. It would not be so bad but my eggs will be here in the next day or so. You can see the heating element in front of the fan. It works very good. I laugh at my antics. Whatever works. I might put the incubator on some bricks....just in case.
