Thought of something else. Did you disinfect or clean that bator really good? Wood can carry a lot of bacteria in it & when you have heat & humidity added it can explode inside an incubator. An easy way would be to add 2 tablespoons of Clorox to a gallon of water & use a spray bottle to spray the inside, wetting everything to the point of run off. Let it set for 20 minutes of so, then dry it as best you can, turn it back on & let the incubator dry itself. When you start it up, you will be able to smell the Clorox, but it doesn't hurt anything. Try not to spray to much on any metal parts. Clorox will eat the galvanize & metal objects over time
