Above, something apparently crushed the top. No damage to box or top of bator.
Above Wafer thermostat you can see the meat probe It's below the wood piece that the heat blows from.
Above, in this picture you can even see the crack at the top of the door. It now has nice wad of paper towels to hold in the heat or try too.
I think after hubby caulks the seams again and adds thicker weather stripping to the door, fingers crossed it will work better. Any other suggestions I should look into? Had one egg hatch and later die but I know it was due to too high temps. They were bantam eggs at that. Pictures don't show but has a hatching tray at the bottom.
